The problem with people not considering this area as a valid source of future energy might be in the use of the term perpetual. Eventually the magnets will decline and the motor will slow. This decline might be compared to the decline we see in uranium. Basically, we are looking for a way to extract this magnetic energy and convert it to mechanical and or electric energy, similar to the way we utilize nuclear energy. We may not have yet developed the formulas for analysis or answers to all of the questions. Dismissing anything as not possible by comparison to what we know currently makes experimentation and discovery of what we don't know impossible. How many times in history has the discovery come first and the explanation years later.
