Is free electricity possible? – Gibbs Free Energy Equation Temperature Conversion
The answer is yes. But the cost must not be a disaster. In fact, much of the free energy that could be used could be converted into useful power by modern technology, such as grid-connected plants like those in the United Kingdom. In this regard, the United States may already be catching up. The question is how to get it. "There's a lot of energy available on the planet," says Stephen Deere, the director of renewable energy at the U.S. Department of Energy's Oak Ridge National Laboratory. "If you can do this cheaply, you can certainly build lots of power plants and get the energy that's available." Most of the available cheap electricity comes from wind and solar; these sources are usually very clean. But what about burning coal? With…
