Steam Dynamo (Thermal Expansion 3)

The Steam Engine is an engine that produces energy from combustible solids and water. A steam engine will not work if not supplied with water and fuel such as coal to burn. It can burn any normal furnace fuel to heat the water. If the amount of energy it outputs is more then the amount used by the network it will power down until it locks up and requires being hit with a Crescent Hammer to restart.

Recipe
The Steam Engine is crafted with three copper ingots, one redstone transmission coil, two copper gears, and one piston.
