A great list and explanation of various types of 'perpetual motion machines' proposed throughout history. You'd be surprised how old some of these ideas are, and yet people are still pushing them...

I love this link! Proving those things are in static equilibrium can make very good statics problems. I came up with a version of the buoyancy motor before (I knew it was impossible, just couldn't see why) and I had to get someone's help to figure out why it wouldn't work. If I ever become a statics teacher one day, I'll give my students some of those problems :wink:.
