-Jed, You said ; ' It is implausible at this stage because jet engines require extremely high temperatures and power density ' I might have missed something but I thought LENR has high energy density. How to get high pressure is an engineering issue if I understand right. I take Rossi's statement as an indication that they can see openings to create a propulsion unit for airplanes.Your timeframe is not my experience (I went to school 300 feet from a jet propulsion lab - probably why I did not like school so much:).The safety aspect is there regardless of which application we talk about. I think the progression is directed by the market so either the easiest or the most profitable. My thinking was that there is resources in the aerospace industry and they know that ROI takes its time and the winner is the one that can command the new technology first and best. How and why and what can be developed I do not know. I am glad that you can see the positive possibility p let us hope that Rossi has everything under control for the sake of LENR and even more for the sake of having cheap energy helping us even things out between different part of the world without having to adopt islam. Exciting is what I think.
