Steam generator

The steam generator is a block which generates energy from burning fuels (the same ones that fuel furnaces). Inserting a fuel causes it to stat heating up. The hotter it gets, the more energy it produces, until it reaches its maximum of 3 J/t. It must be constantly fueled to avoid cooling back down. Instead of providing fuel, you can pump hot air into the bottom side instead (see fluids). In addition, the steam generator must also pull in water through the top side.
