I'd like to create a way to negatively charge the surface of our roadways. And in turn create a vehicle that produces a negative charge.

This would create a zero coefficient of friction and require low energy to tansport vehicles from point A to point B.

Opposing magnetic fields repel each other but generating the fields costs a lot. I think a better solution to reduce friction would be to use rails instead of pavement and rubber tires. Then you can have wheels that are steel on steel and require much less friction. The problem is that friction from the road costs a small fraction of your overall energy loss. Most of your loss is from friction from air. They are already working on getting around this by using massive vacuum sealed tubes for inter-city train rides (and I think mag rails are a part of the design too). That way you can go as fast as you want without the resistance. Also, after you seal the tube, keeping out the air (or at least 99% of it) wouldn't be that expensive.

      Aug 1 2012: I like that idea. Isn't Japan building one like that now? It reminds me of when you go to the bank drive through teller and you send your deposit through the tube in a capsule. Always thought that would be a wild way to travel. I think I'd lose my lunch on the g-forces though.
