In the past few years, we have covered plenty of awesome Stirling engines here. This self-propelled Rocket L1 model car is also worth a look. It comes with more than 190 parts and takes about 10 minutes to assemble. The Rocket is propelled using a powerful Stirling engine.
This vehicle has a stainless steel, brass, and aluminum construction. A pretty nice toy if you ask us. The bad news? Something like this doesn’t come cheap.
