Thanks for posting your rather long dissertation TWICE on this thread.

If you read my post, I did not use the term "new Technology," not that I have any objection to the term. You are not the only one on this thread with a science major. I don't want to get into a long technical discussion
on energy sources for obvious reasons, it would bore the crap out of most readers.

Well aware of the limitations of hydrogen fuel cells or electricity as an alternative fuel source. I was pointing out the fact that no one on this forum is addressing the urgent need for alternative source of fuel and powerplant for aircraft. Since I don't have a PHD in physics I can't offer more concrete examples, but unless alternate source of fuel is found soon, we will all be up the creek without a paddle.
