I don't get it. So you can use heat to make a magnet. We already have permanent magnets. Magnetism, in and of itself, doesn't create energy. You'd have to either pulse the magnet, or move a coil past the magnet. The former seems impossible since you'd have to cycle its temperature, and the latter just gives you an alternator, which we already have. If I'm missing something, I'd like to know. It just looks like, "hey, magnetism!" and some hand-waving.
