Diode arrays that produce usable amounts of energy

Note: Early 2008 I predicted that mixing correct materials and applying a DC voltage would form countless natural microscopic diodes, and that such diodes would rectify to some degree natural ambient thermal energy (NATE). The following two gentlemen have been successfully making such batteries.

Marcus Reid - The Reid battery that never runs out of power. Since 1999 the Reid batteries have been producing usable amounts of power. My detailed analysis on Reid's temperature measurements shows with decent probability his batteries cool when in use, which if true would show that the energy is coming from ambient thermal energy. Reid is trying to market his batteries in addition to further research to improve his batteries. It is possible that the Reid batteries are microscopic diodes that rectify natural ambient thermal energy

John Hutchison - Video at YouTube that shows John's batteries producing usable amounts of power. John claims his batteries do not run down and have been shorted for years. John's description of how he makes his batteries is identical to my description of how such a diode batter would be made. It is possible that Johns batteries are microscopic diodes that rectify natural ambient thermal energy. John is also trying to market his batteries and is unwilling to describe the exact chemicals.
