E 72 LBCE

The E 72 Light Bio-gas Combustion Engine is a simple engine that can be used in the vacuum of space or through any un-harmful gas. It is fueled by bio-gas and can be boosted with compressed oxygen. 1 engine can produce 30,000 joules of energy and 50,000 joules when boosted, and although this may not sound much the E 72 is only half the size of the E 55 OOCE.
