// TURBINE v2 AKA rev4407 Engine reborn!
// How to use it? - Mappers
//
// This is a very good power generating mechanism. All you need is a blast furnace with soaring flames and output.
// Not everything is included yet so the turbine can run out of fuel quiet quickly. The best thing about the turbine is that even
// though something is on fire that passes through it, it won't be on fire as it passes out of it. So the exhaust fumes can still
// containt unreacted fuel - plasma and oxygen that needs to be filtered out and re-routed back. This of course requires smart piping
// For a computer to work with the turbine the compressor requires a comp_id matching with the turbine computer's id. This will be
// subjected to a change in the near future mind you. Right now this method of generating power is a good backup but don't expect it
// become a main power source unless some work is done. Have fun. At 50k RPM it generates 60k power. So more than one turbine is needed!
//
// - Numbers
//
// Example setup S - sparker
// B - Blast doors into space for venting
// *BBB****BBB* C - Compressor
// S CT * T - Turbine
// * ^ * * V * D - Doors with firedoor
// **|***D**|** ^ - Fuel feed (Not vent, but a gas outlet)
