A radical Turbine Range Extender (TREx) for electric vehicles

TREx engine is used in electric vehicles (EVs) to eliminate range concern. It charges batteries on the run when necessary.  Compared with conventional engine driven vehicles, EVs with TREx consume much less fuel. Compared with piston engine range extenders, TREx is considerably superior in low emissions. For example, it can cut CO2 by 60% and NOx by 85% or more.

TREx has features in its radical design and advanced air bearings. The radical design enables the engine to be contained in a space as small as a spare tyre. Air bearings improve the performance and life time of the engine.
