I have disliked cars for quite a long time now. The mechanics of them cause so much friction and wasted energy. Also, I find it ironic that the parts that create the friction with the road (wheels) also slow the car down because of this friction.
So this is my idea and it needs lots of work. Some sort of platform which is where the rest of the frame is built on. Underneath this platform would be multiple fan like devices, like small propellers. These, of course, would alow the vehicle to hover (or I guess fly if you wanted).
Before I go on, is this even feasible? Could these small propellers keep the vehicle at a steady distance from the ground?
Oh, and if these were to be mass produced we could maybe get rid of roads and have some sort of air lanes. Have you ever thought of how much space we waste with pavement.
