I still think that radioactive diamonds made from spent nuclear reactor control rods is the answer for electric power. I say that half in jest and half in all seriousness... about the same power to weight as lithium ion, but a half-life measured in centuries rather than minutes.Fuel cells might be the game-changer for electric cars
Of all things apparently there's a socata tbm-700 that ran lpg in the 80s down under of course. I think theres still a few LPG projects in the uk / australia.Dumb question here :
Any airplanes ever used propane , as a fuel source ?
lol i wonder when a certain peter will decide to add propane to resolve his cooling issues... I mean the diesel guys inject it for better / cleaner burn + its a vaporizing liquid so it has a habit of massively cooling intake air temps behind the turbo's.Propane has more energy per pound than gasoline. There was a large biplane (Skybolt?) powered by propane (archives EAA). Can get more power with high compression. Roush claims equal power with liquid injection.
Aviat had a CH4 powered Husky at Oshkosh recently.
