The difference between an electtric motor and what they claim to have produced is that the rotor in an electric motor changes it's magnetic polarity through the apllication of electrical current while their device does so through the implementation of magnetic shields moved into position with low energy consumption. It sounds like so many other perpetual motion machines.
However they spent $100,000USD on the full page ad in "The Economist" which seems like a lot to spend without doing some preliminary testing on your own.
