1,500 HP engine?!?!? Best left to turbines. Wait! They advertised a tiny "backpack" turbine...which is better suited to piston engines. Amazingly enough, it was almost identical to one of the least efficient turbines ever designed (the Terry turbine) but somehow Cyclone advertised it as having revolutionary efficiency. GE, Westinghouse and Siemens really needed whatever laws of physics Cyclone was using. The problem is, those companies make real products for real customers, limiting them to boring, everyday science and engineering.
