The principle of any engine is that you must have one side that is hot and the other side is cold You convert some of the heat that flows from the hot side to the cold side into useful work Usually the side that is hot is made hot by burning gas and the side that is cold is normal air temperature But using liquid nitrogen as a fuel means that the side that is hot is the normal air
