This present Manual of Free-Energy Devices and Systems discloses the project work of approximately fifty independent researchers into "free-energy" R & D, and spin-off anti-gravity research.
The various researchers cover the spectrum of laymen "explorers" and professionally-trained scientists, with the work of both researcher types pointing to a common end, that of validated "over-unity output" from their various prototype projects.
There can no longer be any serious doubts about the practicality of the various "free-energy" units and systems based on the full-weight of the hardware evidence from at least fifteen different types of projects, as presented in this Manual.
Although all of this presented prototype/project work has been aimed at producing free-energy machines, it has become increasingly apparent that in some cases levitation (anti-gravity) results have been achieved as a spin-off from this basic free-energy development effort.
