    How to incorporate a Hydrogen fuel cell into an electric aircraft for Homebuilders?

    I agree with that. We'd just have to get off corn ethanol here in the states, which uses as much energy (if not more) to produce than we get out of it. On the topic of electric propulsion as a desired trait, the option of a range extender engine like in the greased lightning seems like a less...

    How to incorporate a Hydrogen fuel cell into an electric aircraft for Homebuilders?

    Well it could mean something different for everyone, but every time someone mumbles hydrogen it is usually synonymous with unicorn farts, sustainability, and the color green.

    How to incorporate a Hydrogen fuel cell into an electric aircraft for Homebuilders?

    Isn't the entire purpose of hydrogen to get off fossil fuels? If you're reforming liquid hydrocarbon fuels into hydrogen, why not just burn the liquid hydrocarbon fuels? Hydrogen component weights in a Toyota Mirai: Fuel cell stack: 123 lbs Hydrogen tank (1" thick carbon fiber): 193 lbs...

    Why battery-powered aircraft will never have significant range

    I'll have to be on the lookout for a crashed Cybertruck at the insurance auctions once they start making deliveries. I think Tesla is also achieving better pack-level weight by double-stacking. Kinda like how a big mac only needs 3 buns to support 2 patties.

    Why battery-powered aircraft will never have significant range

    Keep in mind their 144 wh/kg is at the pack level. The best cells right now are around 270 wh/kg, but that's at the cell level. Add on the structure, BMS system, and cooling system and 144 wh/kg is not great but not th at terrible. Even though Tesla's cells are at around 260-265 wh/kg, their...
