This presentation is mainly for people who have never come across free-energy and know nothing about it. So, each chapter deals with just one device and tries to explain it clearly. “JouleThief” There is nothing magical about free energy. I consider that a “free-energy” device is one that outputs energy without the need for having to buy fuel to power the device. We live in a vast energy field and there are many different ways to access that energy and make it into a form which is useful to us – typically electricity. One of those ways is to pass current through a coil of wire and then suddenly which of the current. When you do that, the coil produces a sudden, very large voltage spike which causes energy to flow into the coil from the outside environment. For this inflow of energy to be useful, we need it to happen many times per second, and that required an electronic circuit. Electronic circuits are not difficult to understand, nor are they hard to construc
