Flywheel for energy storage

We established a new theory to acheive that a flywheel may be driven at supersonic speeds under atmostheric pressure, besides was produced a flywheel that would be suitable for use in energy strage and have driven it with great success. We drove this flywheel without vacuum containers on December 11,2001,which was the first drive in all the world. Now this paper offers abstract of a prototype of our flywheel and a theory produces the desired effect. The equipment that proves the new theory consists of a flywheel and some shrouds which cover a flywheel. Each shroud is not of touch with a flywheel and each of them, they can rotate freely a main axis with a flywheel. If a flywheel is covered with N numbers of shrouds, the windage loss torque is calculated as following, Qn=(Qd/(N+1))^2 N : the number of shrouds Qn : In the case of windage loss torque of flywheel with shrouds Qd : In the case of windage torque of flywheel without shrouds It had already never needed to combine flywheel with any vacuum containers that been superintending the 20th centry. We will create an efficiency management system of electrical energy by using this technology. Futhermore we will continue to experimente and develop some practical models relating to flywheel in order that it may work to reduce greenhouse gas and to keep environmentally-safe of Earth.
