First the disclaimers: While I do work for NASA, I do not speak for them. They employ me for my professional capabilities and on occasion my professional opinion. Nothing I say should ever be construed as anything other than my personal opinion. As a NASA employee I am allowed and often times encouraged to say what I think. This and the exceptional people I get to work with every day are what make NASA great and a great place to work.
I wish to respond to a number of things that have popped up on the web in the past few days and weeks. I do this here because I can control the message. Every issue has at least two sides but, only the writer gets to decide how to present them. I do not plan to make discussion of my work on this site a habit and I do not plan to allow any comments to this post. It is unlikely that any email on this topic sent to me will generate a reply. Undoubtedly, bits and pieces of this will be taken out of context and used to support claims and opinions which I myself do not hold. Such is the nature of the Wild West Web (WWW). All I can ever hope to do is to maintain the original content and context. In my opinion, reputable sites will link back to this original content and others will not.
As you have likely already noted, a non-technical video on a patent application for a new technology was made public on a NASA website this past week. It is part of the overall innovation disclosure process. It is just one of the ways NASA communicates with the public about what we do. As mandated by Executive Order, every civil servant is required to disclose an innovation or invention which may be a of value/benefit. Google “NASA technology reporting” if you wish to read the executive order and how NASA has implemented it. If a patent application is filed, a video may be produced to inform the general public of the nature of the invention or innovation. It may be a non-technical piece that communicates what this invention is about and why people might care. Such is the case of the recent video on Surface Plasmon Polaritons.
As for what people are trying to read into this video, specifically my use of the word “demonstrated”, it is my professional opinion that the production of excess energy has been demonstrated when the results of the last 20+ years of experimentation are evaluated. There has been a lot of work done in the past 20+ years. When considered in aggregate I believe excess power has been demonstrated. I did not say, reliable, useful, commercially viable, or controllable. If any of those other terms were applicable I would have used them instead. If anything, it is the lack of a single clear demonstration of reliable, useful, and controllable production of excess power that has held LENR research back. As a non-technical piece aimed at the general public, my limited media training has taught me that less information/detail is generally better than more. I did not produce or direct the video. While I saw the video before it was released, I did not learn of it’s release until the email started pouring in Thursday morning.
There have been many attempts to twist the release of this video into NASA’s support for LENR or as proof that Rossi’s e-cat really works. Many extraordinary claims have been made in 2010. In my scientific opinion, extraordinary claims require extraordinary evidence. I find a distinct absence of the latter. So let me be very clear here. While I personally find sufficient demonstration that LENR effects warrant further investigation, I remain skeptical. Furthermore, I am unaware of any clear and convincing demonstrations of any viable commercial device producing useful amounts of net energy.
So what does extraordinary evidence look like? As a trained scientist, I have been taught the historical standards for acceptance of experimental results or theories. Experiments and theories go hand-in-hand in what is known as the scientific method. Both must be independently tested, replicated, or verified. As a minimum, experimental results must be replicated by an objective and independent party. The nature of the test or replication needs to adhere to the spirit of the original experiment but, should be under the full design, implementation, and control of the independent tester. So, if a device is claimed to be capable of producing excess heat by nature of its operation (i.e., the consumption of fuel via a nuclear process), it must be operated properly. The way power input and power output are measured should be left up to the independent tester. This is standard scientific practice. What would take this to the next level (extraordinary evidence) would be to have the test be an open public test. The nature of the test and specific approach to executing the test should be made public. The conduct of the test should be open to additional 3rd party experts. And finally, the data should be publicly released. Further peer review of all aspects of the independent test is a must. Community consensus is the ultimate goal. Every attempted demonstration of a LENR device that I am aware of has failed to meet one or more of these criteria.
There is one last point I wish to cover. It has been claimed that I no longer give proper credit to Widom and Larsen for their theory. I disagree with that opinion. When I talk to my family, friends, or neighbors about some of my work. I do not cite Widom-Larsen Theory or any of their papers. There would be little point in doing so. Who the intended audience is must determine what you say and how you present the information. If a technically competent person comes across a non-technical presentation they should recognize it as such. To expect that every form of communication is exactly what you need or want it to be is unrealistic. The fact that Widom-Larsen Theory (WLT) was not explicitly mentioned in the video fit the intended audience. It is not an indication that I no longer believe WLT is likely the correct explanation behind LENR. I have been consistent in my professional briefings to indicate that I find WLT is likely correct. It appears in every briefing where I have had the time to include it and where the briefing was intended to be technical. I’ll point to my last public technical briefing at NASA GRC as evidence of this. I will continue to do so until such time that WLT has been demonstrated to be flawed. Quite frankly I am baffled that WLT is not receiving more wide spread attention. Applications of the theory appear to go far beyond LENR. The fact that I did not mention WLT in the Aviation Week article was a mistake on my part. It was a technical article to a technical audience. I communicated my regrets on that omission directly to Lewis Larsen and am quite willing to admit that error publicly – mea culpa.
