Most people don't know it, but excess energy can be obtained from certain gravitational devices. This extra energy is the basis of what has come to be known as overunity energy or free energy. This handbook contains it all – instructions, photos, schematics and diagrams – showing you how to build several proven generators with flywheels, magnets and DC motors. Some of them have an excess output energy of COP = 3.4 (i.e. 3.4x more output energy than input energy)! Best of all, these are relatively easy to build by yourself. 60-page Handbook. $18.00 (Order# 9043)
