Steorn's technology claims to produce free, clean and constant energy, which would provide a significant range of benefits, from teh convenience of never having to refuel your car or recharge your mobile phone, to a genuine solution to the need for zero emission energy production. Think of the implications this would have on sustainable building and green real estate. Steorn is making three claims for its technology. One-->The technology has a coefficient of performance greater than 100%. Two-->The operation of the technology (i.e. the creation of energy) is not derived from the degradation of its component parts. Three-->There is no identifiable environmental source of the energy (as might be witnessed by a cooling of ambient air temperature). Steorn believes that the sum of the three claims is that their technology creates free energy. Visit Website.
