Micro-Machine Part 2

Old Mini Petrol Engine

Two micro-machine posts in two days. Must be fate. The title on the news article calls it new, but it was published in 2003. It's still pretty cool, though it doesn't appear that anyone has done anything with it since then. Actually, I'm not sure if it actually ran. All the effort seems to have been spent on devising techniques for fabricating the tiny parts. More pictures in a couple of PDF's from the original researchers.

Update February 2017 replaced missing picture.
