http://www.vanguardsciences.biz/dvds.htm - Lecture and/or workshop DVDs - Theory, experiments and discussion as well as demonstrations of the Konzen Pulse Motor which appears to produce overunity. Doug explains magnetic 'splatter' and how various coil configurations can be used to recover and add energy back into the circuit.
An explanation of the 'pulse' motor based on insights and information from John Bedini, EV Gray and other types of pulse motor circuits. Doug has built wonderful working models from off the shelf parts in his quest for a working overunity motor. He explains his experiments which led to the term 'splatter' currents, how they are produced, how the coils are wound as well as how the stators are attached and adjusted to give the optimum output. Some believe Konzen is the most likely person to blaze the path to a shared working overunity motor and is currently offering it for testing in the form of kits and models.
