I love shit like this. There is so much amazing design coming out right now. What a amazing time.
From the article “Its X1 engine is a simple machine with just three moving parts and thirteen major components, but it aims to raise thermal efficiency from the 20 percent of a normal gas engine to more than 50 percent, with drastic reductions in weight and size.”
