I saw something yesterday about a mechanical storage medium that would harness power in a flywheel device and then return it on demand. The cool part was the fact that the flywheel was suspended in a magnetic field so that it never really touched the sides and thus reduced friction significantly. This got me to thinking, why couldn’t you do the same thing for car wheels and their relationship to axles? Simply suspended the tire in an electromagnetic field. Imagine the fuel economy of this type of arrangement. By fuel I’m of course referring to electric cars, as doing something like this for gas cars doesn’t seem practical. Of course if you could go back and retrofit gas cars, that would be a game changer as well.
