An Op-Ed Piece; doc’s eclectic views November 1, 2011

As is my want, I periodically check the National Academies Press web pages for workshop notes/articles/reports that appeal to me, not as nuclear waste and energy expert. Rather I explore the various issues at times only ripples and at times tidal waves related to public policy in both American society and that of the world.

Hence this Op-Ed piece. Herein I COPY the prefaces or abstracts from three reports I found both distress and challenging. Unusual for me, I do not editorialize on them, that’s up to you, the reader. I do however highlight sections that made a deep impression on me by either underlining the (if short) or by enclosing them in a text box. I also could not resist my genetic editors syndrome so I split a few sentences in two, or added in italics, a linking word or two. Remember, my stuff is in italics.

Also the graphics are my idea, the NRC reports a captained extensive tables and figures, good technical stuff, but are not into Flesch–Kincaid readability test  levels for their narratives or illustrations. But my friends in the academies will not disinherit me because its all for an educational purpose. _        Doc.

Setting a Biofuels Renewable Fuel Standard

— Choosing an alternative, an all American Quandary [A NRC Study of the Potential Economic and Environmental Effects of U.S. Biofuel Policy]

“In the United States, we have come to depend upon plentiful and inexpensive energy to support our economy and lifestyles. In recent years, many questions have been raised regarding the sustainability of our current pattern of high consumption of nonrenewable energy and its environmental consequences. Further, because the United States imports about 55 percent of the nation’s consumption of crude oil, there are additional concerns about the security of supply. Hence, efforts are being made to find alternatives to our current pathway, including greater energy efficiency and use of energy sources that could lower greenhouse gas (GHG) emissions such as nuclear and renewable sources, including solar, and (also their) environmental consequences of increasing biofuels production. The statement of task asked this committee to provide “a qualitative and quantitative description of biofuels currently produced and projected to be produced by 2022 in the United States under different policy scenarios …

“The United States has a long history with biofuels. Recent interest began in the late 1970s with the passage of the National Energy Conservation Policy Act of 1978, which established the first biofuels subsidy, applied in one form or another to (mostly) corn-grain ethanol since then. The corn grain ethanol industry grew slowly from early 1980s to around 2003. From 2003 to 2007,ethanol production grew rapidly as methyl tertiary butyl ether was phased out as a gasoline oxygenate and replaced by ethanol. Interest in providing other incentives for biofuels increased also because of rising oil prices from 2004 and beyond. The Energy Independence and Security Act of 2007 established a new and much larger Renewable Fuels Standard and set in motion the drive towards 35 billion gallons of ethanol-equivalent biofuels plus 1 billion gallons of biodiesel by 2022. This National Research Council committee was asked to evaluate the consequences of such a policy; the nation is on a course charted to achieve a substantial increase in biofuels, and there are challenging and important questions about the economic and environmental consequences of continuing on this path.

The National Research Council committee brought together expertise on the many dimensions of the topic. In addition, we called upon numerous experts to provide their perspectives, research conclusions, and insight. Yet, with all the expertise available to us, our clearest conclusion is that there is very high uncertainty in the impacts we were trying to estimate. The uncertainties include essentially all of the drivers of biofuel production and consumption and the complex interactions among those drivers: future crude oil prices, feedstock costs and availability, technological advances in conversion efficiencies, land-use change, government policy, and more.

“The U.S. Department of Energy projects crude oil price in 2022 to range between $52 and $177 per barrel (in 2009 dollars), a huge range. There are no commercial cellulosic biofuels plants in the United States today. Consequently, we do not know much about growing, harvesting, and storing such feedstocks at scale. We do not know other than for ethanol how well the conversion technologies will work nor what they will cost. We do not have generally agreed upon estimates of the environmental or Green House Gases [GHG] impacts of most biofuels. We do not know how landowners will alter their production strategies. The bottom line is that it simply was not possible to come up with clear quantitative answers to many of the questions. What we tried to do instead is to delineate the sources of the uncertainty, describe what factors are important in understanding the nature of the uncertainty, and provide ranges or conditions under which impacts might play out.

“Under these conditions, scientists often use models to help understand what future conditions might be like. In this study, we examined many of the issues using the best models available. Our results by definition carry the assumptions and inherent uncertainties in these models, but we believe they represent the best science and scientific judgment available.

“We also examined the potential impacts of various policy alternatives as requested in the statement of work. Biofuels are at the intersection of energy, agricultural, and environmental policies, and policies in each of these areas can be complex. The magnitude of biofuel policy impacts depends on the economic conditions in which the policy plays out, and that economic environment (such as GDP growth and oil price) is highly uncertain. Of necessity, we made the best assumptions we could and evaluated impacts contingent upon those assumptions. Biofuels are complicated.

“Biofuels are controversial. There are very strong advocates for and political supporters of biofuels. There are equally strong sentiments against biofuels. Our deliberations as a committee focused on the scientific aspects of biofuel production—social, natural, and technological. Our hope is that the scientific evaluation sheds some light on the heat of the debate, as we have delineated the issues and consequences as we see them, together with all the inherent uncertainty.”

Why No Conclusions or Recommendations? — “The statement of task calls on the committee to refrain from recommending policies but to provide an objective review of the policy instruments available, including an assessment of the strengths and weaknesses of each in affecting long-term trends in transportation energy use and emissions. Because of the multitude of ways in which individual policy instruments can be designed, targeted, and applied, it was not possible to examine all of their possible variations and outcomes for a sector as large and diverse as U.S. transportation. For example, how fast and by how much fuel taxes or vehicle efficiency standards are raised will profoundly influence the relative prospects of such options for implementation and their effects on energy use and emissions and on other areas of interest to policy makers such as transportation safety, the environment, and the economy. This study is not a modeling exercise aimed at projecting and quantifying the effects of many policy instruments, each designed and structured in alternative ways and applied across one or more modes. The more realistic study goal is to compare the main types of policy options with respect to the main energy- and emissions-saving responses they induce and the challenges and opportunities they present for implementation.”

There is much in this report to stretch you mental muscles. Too, often what we read is distorted by either the silver bullet or golden goose syndrome or by WIIFT. As is usual with NAS reports, there are occasional places where I differ from the conclusions of this consensus report; but consensus is just that — not perfect, just hopefully workable. Indeed where panel members are friends or colleagues, I’ve often argued particular points with them. However, over-all the reports are a very good source of information.

Scientific Legal Evidence Revisited – Reference Manual on Scientific Evidence: Third Edition

On many occasions I have gripped about courts treatment of scientific evidence and at times written in praise of revising the tort system with the wider scale implementation science courts using well-trained certified peer accredited combinations legal experts and scientists, to assist the judge. Cases would not go to juries until the underlying scientific evidence had been evaluated. Why — just on example,  chrysotile based asbestos fibers are relatively low in toxicity so should not be painted with the same brush as Amphibole asbestos.

 This NAP document sings the songs I love to hear; belief and science have their own place.

Only then could a case enter the fault finding juried phase. I would much rather give jury applicants tests in scientific methodology and broad knowledge, but I suspect very few potential jurors would pass such a test. Yes, I hear the screams from lawyers deprived of their cut, civil libertarians and educators.

The NRC Report Summary

“Supreme Court decisions during the last decade of the twentieth century mandated that federal courts examine the scientific basis of expert testimony to ensure that it meets the same rigorous standard employed by scientific researchers and practitioners outside the courtroom. Needless to say, this requirement places a demand on judges not only to comprehend the complexities of modern science but also to adjudicate between parties’ differing interpretations of scientific evidence.

“Science, meanwhile, advances. Methods change, new fields are born, new tests are introduced, the lexicon expands, and fresh approaches to the interpretation of causal relations evolve. Familiar terms such as enzymes and molecules are replaced by microarray expression and nanotubes; single-author research studies have now become multi-institutional, multi-author, international collaborative efforts. No field illustrates the evolution of science better than forensics.

“The evidence provided by DNA technology was so far superior to other widely accepted methods and called into question so many earlier convictions that the scientific community had to reexamine many of its time-worn forensic science practices. Although flaws of some types of forensic science evidence, such as bite and footprint analysis, lineup identification, and bullet matching were recognized, even the most revered form of forensic science—fingerprint identification—was found to be fallible. Notably, even the “gold standard” of forensic evidence, namely DNA analysis, can lead to an erroneous conviction if the sample is contaminated, if specimens are improperly identified, or if appropriate laboratory protocols and practices are not followed.

“Yet despite its advances, science has remained fundamentally the same. In its ideal expression, it examines the nature of nature in a rigorous, disciplined manner in, whenever possible, (in) controlled environments. It still is based on principles of hypothesis generation, scrupulous study design, meticulous data collection, and objective interpretation of experimental results. As in other human endeavors, however, this ideal is not always met. “Feverish competition between researchers and their parent institutions, fervent publicity seeking, and the potential for dazzling financial rewards can impair scientific objectivity. In recent years we have experienced serious problems that range from the introduction of subtle bias in the design and interpretation of experiments to overt fraudulent studies. In this welter of modern science, ambitious scientists, self-designated experts, billion dollar corporate entities, and aggressive claimants, judges must weigh evidence, judge, and decide.

“As with previous editions of the Reference Manual, this edition is organized according to many of the important scientific and technological disciplines likely to be encountered by federal (or state) judges. We wish to highlight here two critical issues germane to the interpretation of all scientific evidence, namely issues of causation and conflict of interest. Causation is the task of attributing cause and effect, a normal everyday cognitive function that ordinarily takes little or no effort. Fundamentally, the task is an inferential process of weighing evidence and using judgment to conclude whether or not an effect is the result of some stimulus. Judgment is required even when using sophisticated statistical methods.

“Such methods can provide powerful evidence of associations between variables, but they cannot prove that a causal relationship exists. Theories of causation (evolution, for example) lose their designation as theories only if the scientific community has rejected alternative theories and accepted the causal relationship as fact. Elements that are often considered in helping to establish a causal relationship include predisposing factors, proximity of a stimulus to its putative outcome, the strength of the stimulus, and the strength of the events in a causal chain.

“Unfortunately, judges may be in a less favorable position than scientists to make causal assessments. Scientists may delay their decision while they or others gather more data. Judges, on the other hand, must rule on causation based on existing information. Concepts of causation familiar to scientists (no matter what stripe) may not resonate with judges who are asked to rule on general causation (i.e., is a particular stimulus known to produce a particular reaction) or specific causation (i.e., did a particular stimulus cause a particular consequence in a specific instance). In the final analysis, a judge does not have the option of suspending judgment until more information is available, but must decide after considering the best available science. Finally, given the enormous amount of evidence to be interpreted, expert scientists from different (or even the same) disciplines may not agree on which data are the most relevant, which are the most reliable, and what conclusions about causation are appropriate to be derived.

“Like causation, conflict of interest is an issue that cuts across most, if not all, scientific disciplines and could have been included in each chapter of the Reference Manual. Conflict of interest manifests as bias, and given the high stakes and adversarial nature of many courtroom proceedings, bias can have a major influence on evidence, testimony, and decision making. Conflicts of interest take many forms and can be based on religious, social, political, or other personal convictions. The biases that these convictions can induce may range from serious to extreme, but these intrinsic influences and the biases they can induce are difficult to identify. Even individuals with such prejudices may not appreciate that they have them, nor may they realize that their interpretations of scientific issues may be biased by them.

“Because of these limitations, we consider here only financial conflicts of interest; such conflicts are discoverable. Nonetheless, even though financial conflicts can be identified, having such a conflict, even one involving huge sums of money, does not necessarily mean that a given individual will be biased. Having a financial relationship with a commercial entity produces a conflict of interest, but it does not inevitably evoke bias. In science, financial conflict of interest is often accompanied by disclosure of the relationship, leaving to the public the decision whether the interpretation might be tainted. Needless to say, such an assessment may be difficult. The problem is compounded in scientific publications by obscure ways in which the conflicts are reported and by a lack of disclosure of dollar amounts.

“Judges and juries, however, must consider financial conflicts of interest when assessing scientific testimony. The threshold for pursuing the possibility of bias must be low. In some instances, judges have been frustrated in identifying expert witnesses who are free of conflict of interest because entire fields of science seem to be co-opted by payments from industry. Judges must also be aware that the research methods of studies funded specifically for purposes of litigation could favor one of the parties. Though awareness of such financial conflicts in itself is not necessarily predictive of bias, such information should be sought and evaluated as part of the deliberations.

“The Reference Manual on Scientific Evidence, here in its third edition, is formulated to provide the tools for judges to manage cases involving complex scientific and technical evidence. It describes basic principles of major scientific fields from which legal evidence is typically derived and provides examples of cases in which such evidence was used. Authors of the chapters were asked to provide an overview of principles and methods of the science and provide relevant citations.

“We expect that few judges will read the entire manual; most will use the volume in response to a need when a particular case arises involving a technical or scientific issue. To help in this endeavor, the Reference Manual contains completely updated chapters as well as new ones on neuroscience, exposure science, mental health, and forensic science. This edition of the manual has also gone through the thorough review process of the National Academy of Sciences.

“As in previous editions, we continue to caution judges regarding the proper use of the reference guides. They are not intended to instruct judges concerning what evidence should be admissible or to establish minimum standards for acceptable scientific testimony. Rather, the guides can assist judges in identifying the issues most commonly in dispute in these selected areas and in reaching an informed and reasoned assessment concerning the basis of expert evidence. They are designed to facilitate the process of identifying and narrowing issues concerning scientific evidence by outlining for judges the pivotal issues in the areas of science that are often subject to dispute.

“Citations in the reference guides identify cases in which specific issues were raised; they are examples of other instances in which judges were faced with similar problems. By identifying scientific areas commonly in dispute, the guides should improve the quality of the dialogue between the judges and the parties concerning the basis of expert evidence. In our committee discussions, we benefited from the judgment and wisdom of the many distinguished members of our committee, who gave time without compensation.”

Essential Health Benefits — Balancing Coverage & Costs <2011>

The academy committee, all volunteers, albeit knowledgeable, managed to stay clear of politicizing, an accomplishment I’m not sure I could equal.

“A critical element of the Patient Protection and Affordable Care Act (ACA) is the set of health benefits—termed “essential health benefits” (EHB)—that must be offered to individuals and small groups in state-based purchasing exchanges and the existing market. If the package of benefits is too narrow, health insurance might be meaningless; if it is too broad, insurance might become too expensive. The Institute of Medicine (IOM) Committee on Defining and Revising an Essential Health Benefits Package for Qualified Health Plans concluded that the major task of the Secretary of Health and Human Services (HHS) in defining the EHB will be balancing the comprehensiveness of benefits with their cost.

“Not surprisingly, the work of this committee drew intense public interest. Opportunity for public input was offered through testimony at two open hearings and through the web. The presentations at the hearings reinforced for the committee the difficulty of the task of balancing comprehensiveness and affordability. On the one hand, groups representing providers and consumers urged the broadest possible coverage of services. On the other, groups representing both small and large businesses argued for affordability and flexibility. The committee thus viewed its principal task as helping the Secretary navigate these competing goals and preferences in a fair and implementable way.

“The ACA sets forth only broad guidance in defining essential health benefits, and that guidance is ambiguous—some would say contradictory.

First, EHB “shall include at least” ten named categories of health services per Section 1302 Second, the scope of the EHB shall be “equal to the scope of benefits provided under a typical employer plan.”
Third, there are a set of “required elements for consideration” in establishing the EHB, such as balance and nondiscrimination.
Fourth, there are several specific requirements regarding cost sharing, preventive services, proscriptions on limitations on coverage, and the like.

Taken together, these provisions complicate the task of designing an EHB package that will be affordable for its principal intended purchasers—individuals and small businesses.

“The committee’s solution is this: build on what currently exists, learn over time, and make it better. That is, the initial EHB package should be a modification of what small employers are currently offering. All stakeholders should then learn enough over time—during implementation and through experimentation and research—to improve the package. The EHB package should be continuously improved and increasingly specific, with the goal that it is based on evidence of what improves health and that it promotes the appropriate use of limited resources. The committee’s recommended modifications to the current small employer benefit package are:

(1) To take into account the ten general categories of the ACA;
(2) to apply committee-developed criteria to guide aggregate and specific EHB content and on the methods to determine the EHB; and
(3) to develop an initial package within a premium target.

“Defining a premium target, which is a way to address the affordability issue, became a central tenet of the committee. Why the Secretary should take cost into account, both in defining the initial EHB package and in updating it, is straightforward: if cost is not taken into account, the EHB package becomes increasingly expensive, and individuals and small businesses will find it increasingly unaffordable. If this occurs, the principal reason for the ACA—enabling people to purchase health insurance, and covering more of the population—will not be met. At an even more fundamental level, health benefits are a resource and no resource is unlimited. Defining a premium target in conjunction with developing the EHB package simply acknowledges this fundamental reality. How to take cost into account became a major task.

“The committee’s solution in the determination of the initial EHB package is to tie the package to what small employers would have paid, on average, for their current packages of benefits in 2014, the first year the ACA will apply to insurance purchases in and out of the exchanges. This “premium target” should be updated annually, based on medical inflation. Since, however, this does little to stem health care cost increases, and since the committee did not believe the DHHS Secretary had the authority to mandate premium (or other cost) targets, the committee recommends a concerted and expeditious attempt by all stakeholders to address the problem of health care cost inflation.

“An additional task related to that part of the committee’s charge directing it to address “medical necessity.” Medical necessity is a means by which insurers and health plans determine whether it is appropriate to reimburse a specific patient for an eligible benefit. For example, the insurance contract may specify that diabetes care is a covered benefit; whether it is paid for depends on whether that care is medically necessary for the particular patient—whether, for example, the patient has diabetes.

‘The committee believes that medical necessity determinations are both appropriate and necessary and serve as a context within which the EHB package is developed by a health insurer into a specific benefit design and that benefit design is subsequently administered. The committee favored transparency both in the establishment of the rules used in making those determinations and in their application and appeals processes. Indeed, since the design and administration of health benefits rather than the scope of benefits themselves are what appear to differentiate small employer plans from each other and from large employer plans, monitoring benefit administration is an important step in the learning process and updating of the EHB.

“Further, the committee stated that a goal of the updated EHB package is that its content becomes more evidence-based. The committee wishes to emphasize the importance of research about the effectiveness of health services and to emphasize that the results of this research, including costs, should be taken into account in designing the EHB package. New and alternative treatments, in the view of the committee, should meet the standard of providing increased health gains at the same or lower cost.

“Since the committee saw balancing comprehensiveness and affordability as the Secretary’s major task, it also recognized that any such balancing affected, and was affected by, individual and societal values and preferences. Thus, the committee recommends that both in the determination of the initial EHB package and in its updates, structured public deliberative processes be established to identify the values and priorities of those citizens eligible to purchase insurance through the exchanges, as well as members of the general public. Such processes will enhance both public understanding of the tradeoffs inherent in establishing an EHB package and public acceptance of what emerges.

“The committee recommended that the Secretary develop a process that facilitates discovery and implementation of innovative practices over time. A key source for this information will come from what states are observing or enabling them in their own exchanges. Moreover, the committee recommends that for states that operate insurance exchanges, requests to adopt alternatives to the federal essential health benefits package be granted only if these are consistent with ACA requirements and the criteria specified in the report and they are not significantly more or less generous than the federal package. State packages also should be supported by meaningful public input. The committee hopes that its work will be useful in assisting the Secretary of HHS to determine and update the essential health benefits and that its deliberations will be informative to the public. As with most issues of importance, the committee’s work involved balancing tradeoffs among competing interests and ideas. We hope this work is a positive step toward effective implementation of a key provision of the ACA.”

Since, in America the Litigative, the recommendations and implementation practices recommended by the EHB will be challenged in court, I recommend you read, if you skipped it, the previous topic on ‘Scientific Legal Evidence”.

Congressional Research Service [CRS]

The CRS is known as “Congress’s think tank” is the public policy research arm of the United States Congress. As a legislative branch agency within the Library of Congress, CRS works exclusively and directly for Members of Congress, their Committees and staff on a confidential, nonpartisan basis. CRS reports are highly regarded as in-depth, accurate, objective, and timely, but as a matter of policy they are not made directly available to members of the public. There have been several attempts to pass legislation requiring all reports to be made available online, most recently in 2003, but none have passed. Instead, the public must request individual reports from their Senators and Representatives in Congress, purchase them from private vendors, or search for them in various web archives of previously released documents.

The CRS is joined by two other congressional support agencies. The Congressional Budget Office provides Congress with budget-related information, reports on fiscal, budgetary, and programmatic issues, and analyses of budget policy options, costs, and effects. The Government Accountability Office assists Congress in reviewing and monitoring the activities of government by conducting independent audits, investigations, and evaluations of federal programs.

You may wonder why there are a number, larger then usual in a non-nuclear specific article, of nuclear related items below?

Biofuels Aren’t Really Green

Cultivate inorganic energy sources instead of biofuels

Interesting, although several a older studies have been published in peer reviewed sources, they appear to have been ignored by politico’s and silver bullet seeking subsidy hunters. Un-green biofuels also  goes against the current governmental biofuel creation goals and subsidy trends.

Has any done a recent updated system study on the effect of all variables on the issue of biofuel potential? The best of what I’ve googled focuses primarily on the transportation sector. Not often, and only weakly is there consideration given to its use for generating electrical power generation in which biofuel would replace, coal, natural gas and perhaps grid linked efficient solar or wind power.

Sustainable, green, renewable, organic—the words come up so often in energy and climate debates that they tend to sound as if they mean the same thing. But of course they don’t. Nuclear reactors emit no carbon and are therefore in a sense green, but uranium is nonrenewable; hydropower is green and renewable but may not always be sustainable, because the ecological consequences can be bad and reservoirs are not limitless; coal is organic, but its carbon emissions make it the very opposite of green. All that is obvious enough. But even so, it may be jarring to hear—as the authors have found and will describe — organic biofuels can’t possibly fuel a growing world economy in a sustainable manner, whereas, in principle, inorganic fuels could.

That inorganic might beat organic contradicts fashionable prejudice, which like all fashion changes with the season. Take the case of the United States: First came the enthusiasm for corn ethanol, its extravagant subsidization, and a farm-industrial miniboom. Then, when corn’s limits started to become better known and its costs more glaringly obvious, we started to hear about the promise of switch grass, a native species of the North American prairie that promises high energy-conversion efficiencies.

All of this knowledge ignored, in parallel to our scientifically trained American legislators allowing and by implication promoting the increased of corn based ethanol. To 15% in gasoline, despite marginal or perhaps negative fuel efficiencies, known engine corrosion problems and the shortage of corn for food world-wide. To mix metaphor, these folks really know which side of their bread is buttered. It’s a shame that there is no legal way to shame them and their staff, as well as the industry lobbyist into using the 15% adulterated fuel for six months to a year.

President George W. Bush first mentioned it in a 2006 speech to the nation. Before long, Al Gore was chiming in too, promising that with adequate government support for research, grass-based fuels could free us from the dual specters of energy shortage and runaway climate change.

In Germany rapeseed has been all the rage; in India, jatropha; and in Brazil, sugarcane ethanol. Yet the plain fact is that nobody really knows when or whether organic fuels will be competitive with hydrocarbon based fuels (gasoline and or natural gas, except under unique circumstance such as hold in Brazil.  Engineering breakthroughs, by their nature, are unpredictable—that’s what makes them exciting. So to evaluate whether organic fuels could ever be in a position to power the world, we looked at them purely in terms of physical resource availability, assuming that the costs would eventually become competitive. We asked how much land and water would be needed to make the quantities of biofuel that a prosperous world would need. We also asked whether there were other sources of fuel and energy that might put less strain on resources while adding less greenhouse gas to the atmosphere.

To our own surprise, the authors note, the model we constructed showed that there is simply not enough land and water to support a prosperous biofueled world. At the same time, it suggested that inorganic sources, such as photovoltaic cells, could in principle do the job. There’s the rub… the words in principle.

There’s much more so read on — make up your own mind, but remember that the 2009 premises input to the authors’ model was already outdated when published. There is, as you all know no thing as constant as change itself. Also check out the last topic in this blog called “statistics and stories. (Doc.)

Nuclear Energy Is A Disruptively Cheap And Simple Way To Boil Water

I’ve combined inputs from two of Rod Adam’s articles to give you a taste of his ideas on nuclear energy related issues. They include his views on nuclear related costs issues and other red flags. I am in total agreement with Rod’s thesis and logic, based on independent reading. No I’m not an economist, venture capitalist, or investment broker, but I am a pretty good systems engineer. Since I’m on a Shakespeare kick, Rod’s articles are as much about “much ado about nothing: but neither does it credit the impossible dream as American nuclear  naysayer preach.

Guys-Gals, France, China, Russia and India are not going either broke by supporting nuclear. Neither will Japan, after they slowly recover from the earthquake-tsunami. Owing ones soul to either the company store or to the international oil magnates is not my version of the American dream. Is it yours?

Why Select Rod’s Articles! — First, he writes for what Steve Jobs would call the rest of us. Experience wise, he is a pro-nuclear advocate with extensive small nuclear plant operating experience and a former engineer officer, USS Von Steuben. He is also the host and producer of The Atomic Show Podcast. Adams and is a frequent contributor to the ANS Nuclear Cafe.  …Mostly, although I’ve looked, I’ve not found any errors in the logic behind his analysis or the validity of his sources.

For the majority of human history, people used their own muscles to provide almost all of the work required for survival and development. A thin slice of humanity achieved a moderate amount of personal comfort and leisure because they were able, often through an accident of birth, to control a portion of the daily work output of hundreds to thousands of their fellow humans. The only sources of work—in the engineering sense—that were not either human or animal muscle came from capturing falling water or intermittently by capturing the breezes through devices like cloth sails or wind mills.

Humans understood fire. They used it to keep warm, to process their food, to produce some implements from metal, and as a weapon of destruction. It was not, however, until inventive people with names like Savery, Newcomen, and Watt started to work out ways of using the hot gas produced when fire boiled water that humans learned how to become masters of the earth’s vast store of combustible materials.

The seemingly simple act of boiling water provided humans the means necessary to gradually invent and manufacture their way out of a life of drudgery. Steam power was the key; H2O had always been important for people, but when they learned to pump it as a liquid, heat it into a pressurized gas, and condense it back down into a liquid, H2O became he vital working fluid that could turn heat into work and force machines to become the drudges in service of human beings. It is not an exaggeration to note that without the act of boiling water to create and use steam, getting rid of serfdom and slavery would have been virtually impossible.

I would bet that most of the people who nod their heads at that phrase have never had to cut and carry enough wood to boil a large pot of water, say for doing a week’s laundry. I am sure that few have ever spent much time watching a coal conveyor steadily feed a large boiler that is producing some of the electricity that feeds the electrical sockets and stoves in their homes. Boiling water is not only important, but it is not as simple as it may seem. It generally requires the consumption of a vast quantity of increasingly expensive materials and it requires a tacit {implied} agreement on the part of everyone in the area of the fire to accept their share of the waste products that are spread far and wide from every fire.

The exception to that general rule is the water that gets boiled by the heat released from atomic fission. Once the work of the talented engineers and builders is complete, operating a fission-heated boiler is a rather simple task. The task is not made simple by sets of complex automation or hard working pumps and conveyors; it is enabled by physics. Once a moderate amount of fuel is loaded into a nuclear reactor, it will reliably and simply produce heat for somewhere between 18 months and 33 years (the later for a Virginia class nuclear submarine) with relatively little additional effort.

There’s a tad more to this historic tale — click the first reference…

Rod concludes the fact is that nuclear energy is a cheap, clean, and even simple way to perform the vital act of boiling water

To get a taste of the economic issues, that red flag nuclear, check out the second link. Rod makes a lie out of many of ways the most virulent anti-nuclear activists have begun focusing almost exclusively on spreading the assumption that nuclear energy means expensive energy. They have been helped in this effort by statements from the established nuclear industry that claim that new plants are so expensive that they require government assistance and incentives in order to get them financed and built.

The fundamental aspect of nuclear energy that the rest of us need to understand is that fission heat is actually quite cheap. The average total production cost from a US nuclear power plant today is just 1.86 cents per kilowatt-hour. That total is normally broken into two pieces – fuel costs and non-fuel Operations and Maintenance costs. For 2008, nuclear plant owners in the US spent an average of just 0.49 cents per kilowatt-hour for fuel and 1.37 cents per kilowatt-hour for non-fuel operations & maintenance. Data from the Nuclear Energy Institute is provided in Rod’s article that describes what is included in those numbers.

Also enjoy the outdated, but still qualitatively appropriate data on US Government and State energy subsidies — =talk about picking favorite or free market distortions.

Okay enough said so just click through. Also relevant, but not part of this articles are the lowered costs when consider either small nuclear power plant (batteries) and modular reactors such as those being designed by Babcock & Wilcox Company for near future licensing.

Can the U.S. Compete With China on Green Tech?

— A New York Times Debate Feature

When reading this article or the ones I referenced, I wonder whether this competition stuff is a smokescreen. Does it really matter who the ever changing statistics is number one. By all estimates the projected markets are so huge that they can’t likely be monopolized. (Green tech, please note is different from controlling a narrow commodity such as rare earth elements (of recent headline fame) or OPEC and petroleum supplies. America is known for its inventiveness, creativity and ‘venturous’ spirit. However that does not mean that we don’t  need to re-assert, despite the risks, our ability to get our competitive manufacturing up to snuff; or we’re back to hind teat.

After all the jobs and profits go to those who manufacture, not the inventors. That why jobs are exported to the lowest cost technically savvy  ‘competent’ producer – iPad’s from China and flat screen TV’s from Japan and South Korea, with some of manufacturing in part outsourced to China. In addition everything I read, that is based on peer reviewed hard science is that small business do not have the ability to create more than a few jobs, it’s all about mega manufacturing, in America, that creates jobs and raises living standards — more of that in a future article.

The Obama administration has sought to promote green technology as a growth engine in the U.S. But even with some government support, new firms have a hard time competing with foreign producers. The U.S. currently accounts for just $1.6 billion of the world’s $29 billion market for solar panels, with China, using aggressive policies, to become the dominant maker of equipment like solar panels and wind turbines. Congress was so concerned about unfair trade practices harming American manufacturers that it recently approved a provision to require the Pentagon to buy only American-made solar panels. Anyone for a trade war?

What are the obstacles for American companies trying to win global markets in clean energy industries? Read the NYT discussion. Can green industries take off in the U.S. and compete globally? What might stand in the way? The topics discussed in the NT sponsored debate and Op-Ed include:

Small and Medium Reactors  — The cases for and against

Challenges in getting large nuclear projects off the ground seems to have renewed interest in small modular reactors. But not everyone is convinced there is a market for smaller plants. Can the SMR developers play ball with the big boys of nuclear?

This year the nuclear energy industry is thinking small, or at least a segment of it is. Everyone from the International Atomic Energy Agency (IAEA) to Nuclear Energy Insider is staging an event or carrying out a study into small modular reactors (SMRs), while manufacturers are gearing up new product designs.

Is the hype justified? It depends who you ask.

SMRs (the acronym also stands for small and medium reactors, defined by the IAEA as having ratings of under 300MW and up to 700MW, respectively) have been around for a long time and have not exactly shown great commercial promise throughout their existence.

The article discusses a variety of efforts ranging from the failed pebble bed SMR to the ongoing active international approaches in a race that appears to be running almost neck-to-neck relative to technology alternatives. The one thing these designs have in common is the concept of using a small sized 50-100 MW nuclear battery maintenance free unit that is installed underground, used for it’s lifetime, retrieved and recycled by it’s manufacturer. No extra external cooling systems, earthquake proof to NRC or IAEA standards, no refueling, no active safety systems… it’s just a battery. The image is the Hyperon Reactor concept.

Take the Pebble Bed Modular Reactor originally planned in South Africa by the company of the same name, in association with African electrical giant Eskom. After six years of development the project was shelved last September, allegedly due to a lack of customers and investors. Poor management and planning, or the world economic downturn?

On the pro side, However, Steve Kidd (deputy director general of the World Nuclear Association) acknowledges that it is probably current energy generation economics that is driving current interest in SMRs: “You don’t need such a large dollop of front end capital to get a programme underway,” he accepts.

Adrian Heymer, executive director of strategic programs at the USA’s Nuclear Energy Institute, adds: “Interest is being driven in part by smaller utilities looking at different types of energy generation and which cannot afford a large nuclear plant. “If you add capacity in 50 MW to 300MW increments it’s easier on the planning. You can bring the units on in stages, so you are still getting 600MW to 700MW in a 10 to 15-year period but you can finance it as you go forward.”

Another advantage of an SMR design, Adrian says, is that because most of the components can be shipped ready-built from the manufacturer, “it doesn’t take as long to build. You can assemble most of the plant in a factory.”

According to Jay Harris, an independent consultant, a further reason why some utilities might be keen on SMRs is because they provide greater base load flexibility as intermittent renewable energy sources are increasingly integrated into the grid.

The danger for a utility that is bound by regulation to accept renewable energy is that if most of its base load comes from a single nuclear source then a peak in renewables could mean a portion of the base is no longer profitable, and there may be further costs if the plant has to shut.

There lot’s more here to tweak your interest, and while you’re reading check out the supplementary references. Of particular interest are the enhanced safety features, and life cycle, including low construction costs and minimal maintainability, advantages. These are in essence small On the negative side, a terrorists may chose to fly a large helicopter with a sky hook and lift it top drop it where it will ‘scare people’.

It’s Just a BIG Battery

ThreeMmodules in the  B&W Concept

Note that what I report in this topical is not the modular reactor concept, which will be the source of another future article. Modular reactor are large scale reactors which can be built and centrally operated using some installed prefabricated modules to fit power needs, but closely resemble the newer generation of standard nuclear power plants. These are being explored as a means of lowering up front capital costs without a need to significantly change the licensing requirements and regulatory approval process

Assumptions for Land Needed by Wind and Solar — An Analysis

Abstracted from Martin LaMonica‘s CNET article::

Imagine if your country had an unlimited budget but a limited amount of land: what renewable energy has the most potential? Rutgers University professor Clinton Andrews and colleagues ran the numbers on this thought experiment and came up with some surprises.

The authors identified clear limits on some technologies, notably biofuels, but concluded that the bigger challenges to renewable energy and land relate to siting energy facilities, particularly transmission lines. Andrews presented an early version of the paper at the Lincoln Institute of Land Policy conference. The goal of the analysis and others like it is to size up the land requirements for different renewable-energy sources which in many cases require more land than fossil fuels and nuclear power. As the U.S. and other countries seek to ramp up renewable-energy production, land use is becoming a more contentious issue. Already plans to build large-scale solar plants and wind farms in the U.S. have been opposed for aesthetic and environmental reasons.

Even for distributed energy sources, such as rooftop panels, permitting and siting issues stand to loom large because upgrades to the electricity grid are needed, the study found. “It’s not so much the land that we need for producing the energy. It’s how we move to where we want to use it,” according to the analysis that Andrews presented.

Professor Andrews goes on to discuss land use associated with

  • The small land needs for Geothermal and concentrating solar thermal production.
  • Alas, the largest energy associated land hog is biofuels, particularly biodiesel.

There’s more so click though and get the rest of the story. I wish that the reporter who shared Professor Andrew’s work had more directly included coal, natural gas and nuclear in the CNET analysis, but that seemed beyond the scope of the reporter interests. Never the less from the material provided in other references I checked in passing, the land use patterns are very clear. The image is from a 2011 C&EN article.

Remember that land use is only one of the trade-offs needing to be considered while planning our hopefully independent energy future and controlling climate change. The obvious cost of the energy produced, when off set by some sort of charge for pollution needs to be considered. Unfortunately the bureaucrats and industrialists of the world seem to be blind-siding this issue, creating a false balance sheet of costs for energy alternative. “Gaia doesn’t care, the laws of nature will take their coursed whether we believe them or not.

A perhaps more scholarly study, the second reference further highlights energy production  land use issues:

Concern over climate change has led the U.S. to consider a cap-and-trade system to regulate emissions. In the referenced articles we illustrate the land-use impact to U.S. habitat types of new energy development resulting from different U.S. energy policies. The authors estimated the total new land area needed by 2030 to produce energy, under current law and under various cap-and-trade policies, and then partitioned the area impacted among habitat types with geospatial data on the feasibility of production.

The land-use intensity of different energy production techniques varies over three orders of magnitude, from 1.9–2.8 km2/TW hr/yr for nuclear power to 788–1000 km2/TW hr/yr for biodiesel from soy. In all scenarios, temperate deciduous forests and temperate grasslands will be most impacted by future energy development, although the magnitude of impact by wind, biomass, and coal to different habitat types is policy-specific.

Regardless of the existence or structure of a cap-and-trade bill, at least 206,000 km2 will be impacted without substantial increases in energy efficiency, which saves at least 7.6 km2 per TW hr of electricity conserved annually and 27.5 km2 per TW/hr of liquid fuels conserved annually.

Climate policy that reduces carbon dioxide emissions may increase the areal impact of energy, although the magnitude of this potential side effect may be substantially mitigated by increases in energy efficiency. The possibility of widespread energy sprawl increases the need for energy conservation, appropriate siting, sustainable production practices, and compensatory mitigation offsets.

Caveat Lector:  I could not Google a copy of the original Rutgers Study by Professor Clinton Andrews, so can not attest to the underlying technical detains in the original article. All posted information was a variation of the LaMonica CNET report

Stories vs. StatisticsA reality check

Years ago I took a graduate school course, at the University of Denver from my favorite faculty friend and colleague Dr. Albert Ritter. The course combined an introduction to the principals of symbolic logic, dipped into the basis of the scientific method and added what appeared to be a segment on ‘how to lie with statistics.” Although I would not have passed the course being simultaneously being overwhelmed with life’s realities. I was simultaneously teaching, developing an organic chemistry Ph. D. curriculum, chasing funding and then building myself a research laboratory, and enjoying a new marriage. Non-the less, the course changed my approach to what I read and how I approached scientific life!   

Many year later, a book “Damned Lies and Statistics: Untangling Numbers from the Media, Politicians, and Activists”, by Joel Best, University of California Press; 1 edition (May 8, 2001) added another nail to my sense of disbelief of ‘public’ infomercials’ on the numerics and cherry-pickled statistics provided by talking heads what ever their titles or positions.


Therefor the following NY Times article touched on a nerve, always, especially after elections or congressional debates, raw and bleeding.


Half a century ago the British scientist and novelist C. P. Snow bemoaned the estrangement of what he termed the “two cultures” in modern society — the literary and the scientific. These days, there is some reason to celebrate better communication between these domains, if only because of the increasingly visible salience of scientific ideas. Still a gap remains, and so I’d like here to take an oblique look at a few lesser known contrasts and divisions between subdomains of the two cultures, specifically, those between stories and statistics.

Dr. Paulos begins by noting that the notions of probability and statistics are not alien to storytelling. From the earliest of recorded histories there were glimmerings of these concepts, which were reflected in everyday words and stories. Consider the notions of central tendency — average, median, mode, to name a few.

They most certainly grew out of workaday activities and led to words such as (in English) “usual,” “typical.” “customary,” “most,” “standard,” “expected,” “normal,” “ordinary,” “medium,” “commonplace,” “so-so,” and so on.

The same is true about the notions of statistical variation — standard deviation, variance, and the like. Words such as “unusual,” “peculiar,” “strange,” “original,” “extreme,” “special,” “unlike,” “deviant,” “dissimilar” and “different” come to mind.

It is hard to imagine even prehistoric humans not possessing some sort of rudimentary idea of the typical or of the unusual. Any situation or entity — storms, animals, and rock patterns — that recurred again and again would, it seems, lead naturally to these notions. These and other fundamentally scientific concepts have in one way or another been embedded in the very idea of what a story is — an event distinctive enough to merit retelling — from cave paintings to “Gilgamesh” to “The Canterbury Tales,” onward.

The idea of probability itself is present in such words as “chance,” “likelihood,” “fate,” “odds,” “gods,” “fortune,” “luck,” “happenstance,” “random,” and many others. A mere acceptance of the idea of alternative possibilities almost entails some notion of probability, since some alternatives will be come to be judged more likely than others.

Likewise, the idea of sampling is implicit in words like “instance,” “case,” “example,” “cross-section,” “specimen” and “swatch,” and that of correlation is reflected in “connection,” “relation,” “linkage,” “conjunction,” “dependence” and the ever too ready “cause.”

Even (science based) hypothesis testing and Bayesian analysis possess linguistic echoes in common phrases and ideas that are an integral part of human cognition and storytelling. … Despite the naturalness of these notions, however, there is a tension between stories and statistics. One under-appreciated contrast between them is simply the mindset with which we approach them. In listening to stories we tend to suspend disbelief in order to be entertained. Whereas, in evaluating statistics we generally have an opposite inclination to suspend belief in order not to be beguiled.

A drily named distinction from formal statistics is relevant: we’re said to commit a Type I error when we observe something that is not really there and a Type II error when we fail to observe something that is there. There is no way to always avoid both types, and we have different error thresholds in different endeavors, but the type of error people feel more comfortable may be telling. It gives some indication of their intellectual personality type; on which side of the two cultures (or maybe two cultures) divide they’re most comfortable. Check Wikipedia,

Okay, that’s right; if the author’s thesis catches your fancy read on… after all there are both philosopher kings and philosophical scientists, although Plato did not distinguish between them.
