At age 76, with some pretty serious health issues, I'm mostly just playing games. Getting a running prototype and some dyno measurements out there to show what's possible when thinking outside the box is my main goal. Most so-called engine builders are too lazy, or incompetent, to explore what's actually possible by combining parts that weren't intended to work together. If I manage to get a few of these Rube Goldberg projects running, I'll leave it to someone more ambitious (or greedy) to put them into production.
