Speed is everything. The same applies when it comes to storing power through rotational energy. This is where EnWheel® is right out in front, at 45,000 revolutions per minute. This has been achieved by reducing frictional losses to a minimum. The entire rotor runs in a vacuum, on non-contact bearings and is made of carbon-fibre-reinforced plastic. This high-tech material guarantees the highest possible speed with the greatest possible strength. The result: a powerful energy storage device with virtually unlimited charging cycles and outstanding service life.
