Unfortunately, you don't know the difference between working and prissing around on the Usenet.

They do a press release a week after they get a grant, about the thing they hope they can invent. John

Were it not for massive government funding combustion gas turbines would never have been developed, certainly not in a timely fashion. Eventually they'll develop a cost effective battery or they'll prove that it's impossible. The funding speeds things up. Bret Cahill

No commercial development whatsoever for 90 years. After massive governmental spending in the 1940s GTs were developed enough to become a commercial success. We see the same thing with Stirling except the time lag is 200 years. The Swedes spent a lot of taxpayer money and developed a 200 bar engine for their submarines which was further developed by Sandia [more gummint funding] and a utility, San Diego Gas and Electric [quasi gummint]. Some transportation breakthroughs might be done privately, i. e.,the wheel motor, but it's crazy to think that all energy solutions can be developed in the garage following the software model.
