It is important to point out that solar, hydro, bio, nuclear, wind energy is an UNPRACTICAL alternative source of energy as they do not meet the demands of this planet. (therefore we need coal, but coal is envriomentally harmful) Inability to meet demands of the world demands means that we homo sapiens will have to continue using enviromentally devasting energy sources such as hydro dams, fossil fuels and oil. We cannot rely on such inconvienent and costly energy methods which produces a very small amount of energy compared to the magnetic generator (exculding nuclear fission/fusion). Unfortunate to say, continuing such ridicious methods of energy will lead to a dieing planet. Quote from: James Roney Stators “Electromagnetic generators which are NOT to be confused with perpetual motion, as magnets wear out and need to be replaced or re-energized. Understand that there in NO energy in the magnet, only the power of magnetism itself from setting the magnet into motion to produce electricity.”
