摘要:
A power conversion and distribution system. In one embodiment low voltage source components convert a high voltage AC power source to a relatively low voltage supply and provide a direct current output. First superconductor wires carry current from the low voltage source components to a load, and second superconductor wires carry current from the load to the low voltage source components. Individual ones of the first wires are grouped with individual ones of the second wires so that wires connected to carry current in opposite directions are in such sufficiently close proximity that additives of self-fields generated by individual ones of the wires during power transmission result in reduction of the magnetic fringe field generated, thereby increasing the current carrying capacity of the wires.

摘要:
A system for converting DC electrical solar generated energy to AC electrical energy. A DC motor is driven by electricity obtained from DC electrical energy producing solar panels. The DC motor drives an air compressor which in turn provides, via Archimedes' principle, a constant flow of air to a submerged cross-flor turbine. The turbine is rotated by the rising air bubbles through the water. An AC generator is connected to the shaft of the turbine. The output of the AC generator is connected to the shaft of the turbine. The output of the AC generator is then fed to the consumer's or homeowner's electrical supply lines. Special cleaning means removes impurities from the air flowed through the cross-flow turbine.
摘要:
An electrical motor-generator converter drawing energy from a low voltage (e.g., 12 volts) battery to operate portable electric tools or the like rated for commercially standard utility voltages (e.g., 120 volts), characterized by the feature that when the portable tool switch is turned on or off the motorgenerator is started or stopped, thereby avoiding dissipation of energy during those times when the power tool is not actually being used.
