Hi I am not a scientist but I have a few ideas that I would like to know how and why they would or wouldn't work. Also any contributions to my thread with ideas or modifications to ideas that might work are greatly appreciated. I want to discuss lifters, ion wind and the works of Tesla as means or additions of conventional means, to produce atmospheric/space propulsion. To my simplistic understanding, lifters ionise the air to produce lift. They require high voltage and a unique configuration of materials in order to produce lift. They do not work in a vacuum but do work in gases and liquids such as air. Normally a wire is used to pass the high voltage energy to the lifter device from the power source. For a lifter to work it needs to be light weight. I have seen a few different demonstrations of lifters with varying amounts of thrust. I am going to take a guess that the greater the surface area where air ionising thrust is being produced, the greater the overall thrust of the device will be increased. I am also going to guess that the higher the voltage, the greater the thrust will be. Also it is my understanding that voltage is a bit like pressure and that in theory the small amount of power contained in say an AA battery could have its voltage stepped up to thousands or even millions of volts. So firstly is there anyway in which a lifter could be designed to hold the weight of its power source? What about if the ionising surface area is greatly increased and the number of layers (adding lifters onto lifters like a multi-storey car park) are increased? What about if the power source were lightweight solar panels? Can light weight transformers be built to step up the voltage? What about if the power source was a nuclear reactor and the whole concept was scaled right up? Also Nikola Tesla claimed to be able to transmit power through the air, if this is correct and power can be transferred through the air with technology we have today then could a lifter be made to operate by transmitting the high voltage power remotely from the ground to the lifter? If lifter technology could be advanced to the point where it can support loads then we could either accelerate a lifter craft to the outer edge of the atmosphere and then switch to a rocket engine or we could create an extremely high altitude space launch platform. Another question I have is, what would happen if a lifter carried compressed air and expelled the gas through and around its ionising thrust producing components to produce lift from it whilst in an environment normally absent of gases such as space for example? If this were possible then a lifter could continue to rise beyond the limits of the earth's atmosphere for as long as the gas supply lasts. Also if lifters work in helium gas then the gas could be helium which is lighter than air and would add to the lift during the atmospheric part of the ascent?
