Abstract
Electrons are arranged so they circulate along a spiral path in a vacuum. The path has a hollow symmetrical shape which is defined by a surface of a toroid. The shape is controllable by a magnetic field and the electrons can be contained within the shape. A containing force can be created by external electromagnetic fields, ions within the vacuum, or by interactions between the orbiting electrons themselves. The contained electrons store energy for later retrieval.
