Steam engine powered by a candle
The engine is a coil of copper tubes filled with water. The ends of the tube are bent and directed to rotate counterclockwise. The steam accumulates by pushing out the water with an explosive jet, which then leads to a partial vacuum in the coil, which draws in more water to repeat the process. The displacement of water occurs in the form of a jet directed from the end of the tube, while the refueling returns to the tube at a large range of angles, so as a result, the engine moves in the opposite direction of the jets.
