Magnetic Propulsion Motor 

Japanese pianist and inventor Kohei Minato has developed a magnetic motor which uses almost no electricity.
Minato's motors consume just 20 percent or less of the power of conventional motors with the same torque and horse power. They run cool to the touch and produce almost no acoustic or electrical noise. They are significantly safer and cheaper (in terms of power consumed), and they are sounder environmentally.

They only use electrical power for the two electromagnetic stators at either side of each rotor, which are used to kick the rotor past its lockup point then on to the next arc of magnets. Apparently the angle and spacing of the magnets is such that once the rotor is moving, repulsion between the stators and the rotor poles keeps the rotor moving smoothly in a counterclockwise direction.

With the help of magnetic propulsion, it is feasible to attach a generator to the motor and produce more electric power than was put into the device. Minato says that average efficiency on his motors is about 330 percent.
He currently has 40,000 in production which will be used to power industrial fans in Japanese industry. He's also developing car air conditioning fans and looking in to home appliances, personal computers, and cell phones.
