NASA Zawodny clarifies his views on Rossi and Low Energy Nuclear reactions on his own website

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.

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 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.

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.
