Shine a heat lamp onto the rubber bands on one side of the heat engine. As the rubber bands are heated, they contract, moving the center of mass away from the center of rotation. This causes the engine to rotate!

Ummm . . . I'm genuinely confused. Wouldn't the heat make them expand/relax?

Not that the end result would not be the same, of course.

unsure if rubber expands or contracts when heated. either way the centre of mass moves and the wheel turns.

It contracts, one of the few substances that does.
