So, today I learned that a company called LiquidPiston has developed a super light go-kart engine that weighs 4 pounds and makes 3 hp. While this may not sound very impressive at first, when you realize that current go-kart engines produce about 6.5 hp but weigh 40 pounds, the benefits really stun you (at least they did me). However, the best part is that these are rotary engines. Keeping this in mind, I immediately thought of Mazda and how they want to bring back the rotary but have huge challenges to overcome. Well, if Mazda and LiquidPiston were able to collaborate and scale these engines up to sports car levels of performance, then we could potentially see this come to fruition sooner than we ever thought possible:

I know I’m being overly optimistic but I find it exciting to think about regardless.
