Magnetic Power, Inc. (MPI), in Sebastopol, California, has excellent laboratory developments that I believe are very close to big breakthroughs for commercial potential. They have several "magnetic motor" and other related energy source inventions that are currently laboratory curiosities.

He and MPI have developed a room temperature superconductor that was funded for several years by US Air Force grants. It has been kept quiet, but is very real. They did demonstrate superconductors, but have not been successful yet with making long enough wires to be useful. I have had one of their superconductor samples in my hands. All I could verify is that it was a plastic coating on top of a piece of copper, and measurement across the plastic layer was a "dead short."

The Correa's PAGD is one of the best scientifically developed new energy devices I know. It produces electricity in the kilowatt range from a vacuum tube that you can hold in two hands. They say the energy source is the vacuum continuum of space. Regardless of the source, it is very real.

The Correas, like Roger Stringham, are scientists and lack the business support to move this project forward.

General Motors looked at it. GM's engineers loved it, but upper management stopped the deal because "electric cars are window dressing," even with the energy being totally free. GM is still too close to oil interests.

Electra Energy AG is in the process of developing renewable energy sources and their commercialisation.

The “Silicate Cell”, an energy conversion technology which is currently being developed by us, belongs to a completely new class of electric systems. They are called “asymmetric electric systems”. These generators receive energy from quantum vacuum or space–time and convert it into electrical or mechanical energy. The advantage over conventional energy conversion systems is, that these technologies deliver energy permanently and emission free.
