A company named Steorn has came up with an interesting motor/generator. They have posted a video to Youtube demonstrating how their electric motor does not experience an increase in current or voltage under load. It's a pretty cool video. Who knows if their claims are all true, but their motor seems to be different than anything I have ever heard about. It uses toroids as stators!
