While steam technology is rarely used today, it has served as inspiration for other modern technologies that rely on external combustion to power a device. During external combustion, some type of fuel is burned within an independent combustion chamber. Lines filled with fluid transfer this heat energy into the motor, where the sudden increase in heat is used to drive one or more pistons.
