The patent for the Shoulders' device states that the source of the energy appears to be the zero-point radiation of the vacuum continuum. The plasma device by the Correas was presented at the Third International Symposium on New Energy and is being developed in Canada. The German inventor claims that his device can be scaled up to power-plant size. No publishable information is available on the other two devices. These devices all appear to obtain their excess power from the aether.
Super magnets used in super motors provide excess mechanical power.
Two separate super magnets have been developed in Japan. These developments provide magnets at least twice as strong as previously accomplished. The Takahashi motor, based on the super-strong Takahashi magnets is reported to provide sufficient energy so that a moped can be powered and still charge the battery. Obviously, claiming this type of performance would lead to ridicule in almost any engineering facility. Reports are expected later this summer or fall.
