Top 5 Free Energy Technologies

PESWiki is devoted to covering, reporting and educating us on alternative energy technologies - from conventional methods such as solar, wind, geothermal, tide, wave, river on the one hand; to very unconventional or "exotic" technologies such as magnet motors, overunity electromagnetic motors, gravity motors, cold fusion, and vortex technologies on the other. Their purpose is to help the most promising clean energy technologies move forward, and some of these exotic technologies often languish for lack of attention and support. http://Top5Energy.com
The top five exotic technologies that they know of that are closest to market follow below here. PESWiki covers the whole spectrum of clean energy technologies.
These are expanded at http://pesn.com/2012/01/21/9602018_Top_5_Free_Energy_Technologies_Unfolding_Now/
Andrea A. Rossi Cold Fusion Energy Catalyzer (E-Cat) - Italian inventor, Andrea Rossi's E-Cat produces useful power from the fusion of cheap and ubiquitous hydrogen and nickel into copper at relatively low temperatures and pressures, with no residual radiation. On October 28, 2011 they commenced commercial sales of a 1 MW plant. Independent validation scheduled to be done by the historic University of Bologna.

Breakthrough Solid State Generator - We have finally been given permission to discuss this technology that we consider to be at the very top of our list of emerging clean energy technologies. Solid state, low (for now), continuous power, commercial in maybe 24 months, cheap, high power density, no radioactivity, no existing physics laws broken. (PESN and BeforeItsNews; July 23, 2011)

 
PlasmERG's Noble Gas Engine - Nobel (inert) gas engine patterned after the Papp Engine, would cost 1/3 what a comparable output engine would cost, while its fuel would cost a few dollars per month -- negligible; totally revolutionizing the renewable industry. Nine months of running time logged. Company is gearing up to go into production. (PESWiki; [updated March 22, 2011])

 
Power from CO2 and Fly Ash - By eliminating CO2 emissions, producing fuel, and reclaiming valuable metals from fly ash and flue emissions, MP BioMass offers technological solutions for coal power plants and other CO2 emitters to not only keep them from being shut down but increasing their profit margin. (PESN and BeforeItsNews; January 11, 2012)

 
The Potentially Core-less Cold Fusion Hyperion of Defkalion - Today, Defkalion Green Technologies issued a press release and a data sheet about their Hyperion cold fusion based products. However, no demonstration was performed, and no test data was released. Also, we have no way of knowing if they are simply using the E-Cat technology without Rossi's permission.
