    The rocket was designed to be powered by combined liquid nitrogen, gasoline, and liquid oxygen. On learning that Blackmon wanted to launch his rocket from a nearby farm, the Civil Aeronautics Administration notified the U.S. Army. Blackmon's rocket was examined at Redstone Arsenal and eventually grounded on the basis that some of the material ...

    en.wikipedia.org/wiki/Steam_rocket

    The water is allowed to escape as steam through a rocket nozzle to produce thrust. [1] Steam rockets are usually pressure fed, but more complex designs using solar energy or nuclear energy have been proposed. They are probably best known for their use in rocket-powered cars and motorcycles, and they are the type used in aeolipile.

    en.wikipedia.org/wiki/Antimatter_rocket

    An antimatter rocket is a proposed class of rockets that use antimatter as their power source. There are several designs that attempt to accomplish this goal. The advantage to this class of rocket is that a large fraction of the rest mass of a matter/antimatter mixture may be converted to energy, allowing antimatter rockets to have a far higher energy density and specific impulse than any ...
