Whoopee.
Let me know when they can fly 4 hours at at least 120 knots.
Hello Jim,
I recall researching this with you some years back in this newsgroup.
Technology is advancing, and hydrogen powered fuel cell based electric power is
on the horizon.
At the 2014 Consumer Electronics Show I spoke with Toyota engineer Ms. Jackie
Birdsall about Toyota's FCV concept car on display there. Here's link to a
video: https://www.youtube.com/watch?v=2bluUNxVLhE. She told me that their
fuel cell was 60% efficient in producing electricity from oxygen in the air and
compressed hydrogen; this is in contrast to ~30% efficiency of internal
combustion engines. If true, that will enable this technology to surpass
current propulsion technology. She also said the hydrogen would be compressed
to ten bar, which would raise its energy density comparable to that of
gasoline. So, it would appear that your dream specifications could be
achievable soon.
Best regards,
Larry
