Everybody but the oil companies wants electric aviation to take off as
quickly as possible, if you'll pardon the pun. The aviation industry
is a huge polluter, and electric aircraft will not only be cleaner,
but significantly cheaper in terms of energy and maintenance. The
problem is batteries, whose terrible energy density is simply not up
to any practical aeronautical purpose at this stage, and there's no
guarantee that the vast amounts of research going on in the battery
sector will change that any time soon.

If:

1. They create a hydrogen infrastructure that exists across the US at
most GA airports
2. They create high performance 300+ HP engines running on Hydrogen
3. 1 for 1 replacement of fuel tanks to IMPROVE the plane's performance
4. Conduct this upgrade at a cost similar to a replacement engine

Sign me up. At this point, hydrogen fuel cells in cars have failed
hard.


That's because current fuel-cell automobiles use dirty gaseous H2 fuel
derived from petroleum. Liquid H2 liberated from water by hydrolysis
has the potential to power aircraft efficiently and cleanly either
burned in your (300-hp) Continental IO-520-K or (300-hp) Lycoming
IO-540-K1E5.

But there are is new fuel-cell technology on the horizon:

Meanwhile, electric powerplants on planes are in the infancy. My
bellanca super viking can take me comfortably 1000nm on full tanks.

Daniel,


Thank you for your comment. But, it would appear that you are doing
the equivalent of comparing a ability of a newborn baby to that of a
full grown adult. Consider this:

I wasn't really comparing that tech to the engine on my plane or any
other plane. The tech is a far cry, distant cry, from replacing anything
equivalent on an airplane with a tried and true engine. It's my way of
saying "I'll keep what I have thank you." Just in the last few years
there's been a push to install diesel engines so that we could go to jet
fuel. Now hydrogen? I just don't see it happening anytime soon.

"Your analysis fails to consider liquid H2's ~3X better energy
density compared to gasoline. Further, cryo-coolers are able to
condense liquid H2 at atmospheric pressure with very modest power
requirements (~100W). Liquid H2 overcomes the high-pressure
storage requirement for H2 gas. So, a membrane hydrolyzer powered
from a photo-voltaic array employing a cryo-cooler
https://trc.nist.gov/cryogenics/cryocoolers.html could produce
"green" liquid H2 fuel for fuel-cell use rather inexpensively. To
wit, the US Navy flew a liquid H2 powered aircraft for three days:

I made no analysis. Just giving my opinion. I'm glad someone's
optimistic about all of this.

And then there is this possible option at improving hydrolysis
efficiency:

If you object to liquid H2 storage, here's a novel technology:
https://www.youtube.com/watch?v=Ytg23mDd1a4
Former Area 51 employee Bob Lazar is interviewed by Visual Effects
Supervisor Jon Farhat. In this video, they discuss what H1
(hydrogen) is, how it is created and it’s potential in the
automotive sector. In addition, Bob show us he has his own
particle accelerator which he uses to create 6Li (lithium-6) H
(hydride) for H1 storage.

6Li is used to store hydrogen safely and efficiently. It is also
one of the key components in making a thermal-nuclear weapon, but
by itself is not dangerous. Because of crony capitalism and
ignorant politicians, the US government has banned 6Li and the
buying and selling of it. However, the making of 6Li H yourself
with your own particle accelerator IS NOT!

Bob uses solar panels to power an H1 generator which produces H1
from H2O (water). For the safe and efficient storage of the
dangerous H1, 6Li H must be created with a particle accelerator
and used for H1 storage in high compression tanks. With the H1
generator, H1 is forced into the 6Li H tanks through the syringe
compression process. FYI, „hydrogen vehicles” are also known as
„fuel cell” vehicles.

Bob is the owner of United Nuclear Scientific and
Switch2Hydrogen. Jon is the owner of ODEMAX and director of this
video."

All that said, I envy you buzzing around in your luxuriant Viking even
if it is made of wood. Have fun, and inspect for dry-rot. :-)

Best regards,
Larry Dighera
