What are inertia batteries?

frowheels are a way to store energy into rotary momentum (kinetic energy) of large wheels sealed in a vacuum. They are used as a way of storing and release of large amounts of electricity, and although their storage method is non-chemical, the field of inertias is sometimes called batteries . Since the storage method is more mechanical than chemical, the amount of energy stored is limited by the inertia size, its ability to rotate quickly without tearing and designing the engine/generator. The collection has found that large, fast energy explosions are needed in specialized applications, for example in military railway weapons or to ensure electricity to ignite fusion reactions. They are therefore relatively cheap, reliable and low maintenance. The flywheels have existed for centuries, but only recently we have developed high quality vacuum, magnetic bearings and durable materials necessary to store a significant amount of energy in flywheels. In addition to being able to scareT significant amounts of energy include other advantages of inertias of their virtually unlimited lifetime, unlimited recharge and environmentally clean nature.

Many flywheels are made of steel, iron or various composites. The maximum rotation per minute for these materials is about 1,000-5,000, depending on the size of the wheel. Experiments used carbon fiber -based flywheels for excellent performance. The best material for flywheel is possible carbon nanotubes or buckminsterfullerene, a substance with a tensile strength several times in a diamond. However, the cost of the material causes it is currently prohibited for use in the inertia systems.

The

pick -up was offered as ideal energy storage systems for Uninterrupted Power Sources (UPS) and electric cars in the future. Because the inertias are to be spinning very quickly, they must have even density and be without any microscopicthe deficiencies. A small crack can be enlarged and caused to tear the wheels and fly in more directions, in the disaster it is sometimes called a flywheel explosion . Storovers have a conversion efficiency of about 80%, which is considered essential.
