For our purposes, "free energy" is defined as energy that is obtained from a source that is available free of charge and is non-depleting. The devices that harness this energy, are not free; so the quest is to find those methods that are most efficient, cost effective, reliable, feasible, and safe.

The purpose of this website is to feature those technologies the fit this pursuit.

Free Energy

Physics

• Thermodynamic free energy, the total amount of energy in a physical system which can be converted to do work, in particular:
  • Wikipedia:Helmholtz free energy, the amount of thermodynamic energy in a system which can be converted into work at constant temperature (called work content in chemistry).
  • Wikipedia:Gibbs free energy, the amount of thermodynamic energy in a system which can be converted into work at a constant temperature and pressure.

Economics

• Energy with no or negligible feedstock cost, including solar power, telluric power, water power, and wind power. Here at PESWiki, we also present a myriad of more exotic free energy mechanism including cold fusion, magnet motors, gravity motors, and electromagnetic overunity.

Engineering

• Most renewable energy sources
• Electromagnetic free energy, a.k.a. radiant energy

In engineering, free energy means an energy source available directly from the environment and which cannot be depleted (so it is available in effectively unlimited quantity). Free energy, in a strict sense, is energy directly transceived from the environment, and utilized without any artificial aid.
