This is the second and improved version, it caries a payload heavier than a lifter itself!!! Automotive ignition coil is powered by solid state switch from a low freq signal generator. Just look at those sparks striking like a lightning! That amazing apparatus produces lift without any moving parts, by using electrical power to ionize and accelerate air around it, just like an invisible propeller! Exact science behind it is still not 100% understood. I built this one when I was a sophomore in Russia. Got bored and found the way to entertain myself:)
