Non-polluting engine for the Segway? - APRIL 16, 2002 THE Segway, Mr Dean Kamen's motorised scooter, has sparked the public imagination like few other inventions in recent memory.
But recently-published patent applications bolster the tantalising speculation that Mr Kamen may indeed have something much bigger up his sleeve than the cute scooter.
His friend, Mr Robert Metcalfe, has been quoted as saying that ''it'' was ''bigger than the Internet'' and ''almost as big as cold fusion would have been''.
