This may sound vague so allow me to clarify. I’m interested in the possibility of very light flight, which, to be optimal, requires a lack of fuel as such. So I’m wondering about ‘fueless’ propulsion, something that does not require chemical fuel, but may be powered off of electrical energy ionizing the atoms in the air, sort of like an ion thruster, without the need for a supply of xenon gas or the like, but something that could utilize the air itself. Or anything similar. And also, would it be possible for something like that to fit in the palm of ones hand and produce enough thrust (with four thrusters that is) to lift say, a chunk of gold-aluminium-titanium alloy the size of an average male?
