Bob Greenyer, Martin Fleischmann Memorial Project, talks in depth about Magneto Hydro Dynamics, using the casimir effect to harness electron clusters to generate electricity from the electromagnetic universe all around us. The key is frequency, pulse, magnets, lasers, plasma. Sacred geometry, self organising toroidal structures, a wheel within a wheel within a wheel. See also Malcolm Bendall's plasmoid generator.
