Apparent Source Theory ( AST ) is a new interpretation of absolute motion already proposed by this author. AST easily explains many light speed experiments, including the Michelson-Morley experiment, the Sagnac effect and moving source experiments. AST has also been extended to electrostatics, revealing a mysterious nature of electrostatic fields. After I completed developing the major part of AST, I came across an idea that, if two oppositely charged spheres are fixed to the two ends of a rigid rod , and the system is in absolute motion, according to AST, the charge-rod system will be subjected to a net electrostatic force and hence accelerate, implying free energy and reactionless thrust ! Obviously such a possibility would be very exciting, if it really existed. But I was also disappointed because, if free energy doesn’t really exist, this would imply that my theory (AST ) is wrong. I had never heard of such an effect before. Later I found in the internet that such an effect in fact exists and is known as the Biefeld-Brown effect and with unknown origin. Although AST neatly predicts this effect and can be a very compelling explanation, I feel that it still needs to be developed . The purpose of this paper is to invite and inspire theoretical and experimental researchers to work on this exciting technology. Exciting possibilities have been presented for this purpose. For example, according to AST, it is possible to produce by a small free energy device, made by stacking large number of capacitors, a net force that can lift an object as massive as an aircraft carrier. It is shown that the net force on the capacitor is directly proportional to the square of the applied voltage, inversely proportional to the square of plate separation distance, directly proportional to the area of the capacitor plates, directly proportional to the relative permittivity of the dielectric material, and directly proportional to absolute velocity for absolute velocities much less than the speed of light. That the net force is directly proportional to the square of the electric field strength implies that dielectric materials with the highest dielectric strength are vital to the realization of free energy devices. Diamond is the most promising material for this, with dielectric strength of 2000 MV/m.
