The Closed Loop Implosion Turbine is a free-energy and propulsion device in one. Unlike other rotary and solid-state overunity machines it is unique in that it has a self-similarity to the architecture of space itself. For a detailed explanation of how it works (or will when I get funding for a proof-of-concept prototype) see the Schauberger's Legacy piece at the main page. An enabling abstract is available to those serious about investing in this endeavor. This is an animation of the Closed Loop Implosion Turbine
This is the original drawing
After the hyperbola profile was lathed it revealed an egg-shaped stator
The following four pages are excerpted from Jeanne Manning's THE COMING ENERGY REVOLUTION and discusses the work of another Schauberger proponent.
