A hybrid car doesn't have to go at supersonic speeds while pulling high
G's. The blade assembly is cast in one solid piece. As for the hot
exhaust, ambient air is added so that what leaves the rear is no hotter
than any other normal car. It's hardly an insurmountable problem.
Please, understand that we're not talking about putting a airplane
engine in a car but of a new adaptation of turbine technology to the
required application. It's a whole different ballgame so all the old
notions and prejudices we have of this technology need to be revised.
