I saw it posted on the local metalworkers club mailing list. Since it didn't run on fuel some of the guys weren't impressed. Those that weren't impressed have built a few model engines that do. One of them even makes the tiny spark plugs for them (1/4"-3/8" tall).
I should add, I was impressed regardless of what it runs on!
