I have no use for them, but if it didn't cost you much, aluminum melts easily in a $20 DIY rocket stove and can take any shape you want.
For instance, a radiator that you fit between the rocket stove and a Peltier module to generate some electricity.
Look it up on YouTube, many videos of rocket stoves and aluminum casting.
