An electric motor that produces about 120% more kinetic watts than a
conventional motor of the same value has been developed and could soon
be available on the commercial market.Prototype developer Zhaan Jordaan
reports that the concept behind the energy efficient drive, which was
presented to an independent electrical engineer for testing, is to use
12 volts of DC power supply with 7,5 applied ampere (A).
This could enable a drive to produce 288 W of mechanical power on a
Dynamometer. Jordaan adds that this is achieved using no fuel on the
motor. This could equate to a drive unit that is 300% more efficient
then a conventional...
