Alfie Carrington, from Michigan, has built a flying machine in his garage (he hopes). The machine has a rotary engine that will stimulate two discs for a magnetic levitation system. Somehow those discs power propeller blades. It seems more like a cool hovercraft to me, but I don't know very much about things like this. Alfie hopes to get this thing off the ground in 8 months or so. Aeronautical engineers claim that the centrifugal force of the discs are more likely to tear the thing apart than create lift.
