Free Energy – The Quest For A Perpetual Motion Machine
Perpetual motion machines (i.e., devices that, once set in motion, would continue in motion forever, with no additional energy required) - are they possible? Well, not according to the first and second laws of thermodynamics. First law of thermodynamics: When energy passes, as work, as heat, or with matter, into or out from a system, its internal energy changes in accord with … [Read more...]
