Eplus3D has worked with UCL Rocket on liquid rocket engines. Right now, they’re working on a regenerative liquid oxygen (LOX) and isopropyl alcohol (IPA) liquid-cooled architecture. These rockets use IPA as a coolant before igniting it along with the liquid oxygen in the combustion chamber. The cryogenic engine (because the LOX is cooled to under minus 183 degrees to stay liquid) uses the temperature difference between the LOX and the heat created by combustion to insulate the rocket and keep it from, in effect, melting itself during combustion. Through the use of the very dense LOX, it can take lots of fuel, which is also very efficient and could burn for very long periods. If you get the additive portion of this engine architecture right, then it could be a comparatively very inexpensive
