## Description

Kelly D.A. The Manual of Free Energy Devices and Systems Vol. 2 1991 [pdf 128sc 123c. 13.49mb] 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.
