My favorite project was the MIT silicon wafer etched jet engine. Like full jet engines the size of a pencil eraser. They also made solid rocket engines etched out of silicon.
Super interesting stuff.
- jeffreyrogers 6y agoThat sounds cool. I found this article[0] that I think is about the research you're describing. It must work a little differently than a conventional jet engine since I don't see how they could have bearings on the shaft for something that small. Any idea how they solved that problem?
