If your car is a diesel, it will run. Liquid hydrogen, the fuel that powered the space shuttle’s main engines, could work, says Manuel Martinez-Sanchez, an aeronautics and astronautics professor at the Massachusetts Institute of Technology. But keeping hydrogen liquid requires maintaining it at a temperature below about -432°F. Storing it in a garage would be tricky, as would keeping it from freezing the engine.
RP-1 would work even better. A kerosene fuel developed in the 1950s as a more efficient alternative to alcohol-based rocket fuels, RP-1 powered the Soyuz and Falcon 9 spacecrafts. “It’s a close relative of diesel fuel, so there is no real problem using it in diesel engines,” Martinez-Sanchez says. “The only special thing about RP-1 is a lower volatility and a higher viscosity, so the engine might not run well on cold days,” he says.
RP-1 probably isn’t worth the trouble, though. Rocket fuel is less efficient than gas, and it wouldn’t even make a car go any faster.

World's best pie apple. Essential for Tarte Tatin. Has five prominent ribs.
So pretty. So early. So ephemeral. Tastes like strawberry candy (slightly).
My personal fave. Ultra-crisp. Graham cracker flavor. Should be famous. Isn't.
