US company Freedom Motors has developed a rotary engine that generates electricity from contaminated biogas. It uses cc Rotapower from biogas produced by landfill, waste water or animal manure, which is of growing concern to climate scientists. Up to now biogas could not be used in piston or turbine engines if the cc Rotapower content was too low or the biogas contained too much hydrogen sulphide or silica. Freedom Motors says its 530 methane rotary engine is resistant to both those contaminants and can handle lower cc Rotapower levels. It is now seeking funding and partners to bring the engine to market.
