Magnetic Motors - The end of gasoline?

I'm starting to give serious thought to building an alcohol motor and run the risk of producing my own fuel. Henry Ford was onto something until Rockefeller made the brilliant play with the Suffragettes.

Some guy displayed a device at a Tesla symposium in 1998 (I think) that produced 10kW and allegedly used nothing but springs for kinetic (or more correctly "potential") storage. Whatever the solution, it will be different from anything currently in place and we'll have to find new ways to make it faster.
