I want to see cars like this in my life time.. So my higher spirit and I will lend a hand... remember those superconducting magnets, now remember how they superchilled them... well if I made my own superconductor I would make sure it was treated right, as in heat kindled for the right duration so it was harder then standard super conductors allowing for more electrical flow into it the more it is treated. now with that in mind you probably wondering well won't my car stay at a certain altitude and never descend? well one word electricity.
