I write as one with a background in molecular biology and nothing in engineering. Looking to advance an idea of using a former rocket fuel for a terrestrial purpose. A mixture of liquid oxygen and ethanol was used in past decades.. What engine elements would be required to convert this fuel energy into some type of mechanical energy... say to turn rotors. What equations would be involved in such a case. Much thanks in advance for an informed reply.

Ethanol is used now as a gasoline replacement for many engines.

Liquid oxygen, LOX, is too expensive to produce for use on the Earth's surface. Instead, use the atmosphere which is about 20% oxygen. That will also save significantly on transportation costs.

Hmm... the current price per liter of LOX is cheaper than gasoline or diesel in the UK. But of course air is free.
