📁 Unproven概念
Category scope includes "free energy" concepts and inventions, descriptions of energy inventions that have not yet been successfully demonstrated, concept papers describing potential futuristic technologies that are unrelated to energy technologies now used, articles about energy inventions and R&D efforts that never lived up to the claims that were made for them, and energy technology ideas that are currently considered unorthodox. Many of the concepts described by sites in this category are generally considered to violate the second law of thermodynamics or other laws of physics. Other concepts described here may have merit, but have yet to be successfully demonstrated. Note that symlinks are provided to categories for Cold Fusion and Orgone Energy.
