I made some things: Thermomagnetic Motors v1 "Hope" and V2 "Voldemort" and v3 "Wilson"
I made a thing!
It's a thermomagnetic motor, Version 1, based on this Tesla patent.

It works, but not reliably. I've played with it a lot, and think I've sorted out the figured out the key to the reliability issues.
Along the way, I build V2, a lovely exercise in minimalism that failed utterly. I call it Voldemort, and won't mention it again.
This week I 3-d printed the parts for V3 "Wilson" at the Marietta Makerstation.
With a sufficient quantity of alcohol, this bears a resemblance to the character in the Castaway movie.
You might think "Hey, won't the 3-d printed plastic melt from the heat?" You'd be exactly right. This unit will probably melt during testing. I hope to get some good data before it dies.
Here's what it should look like when finished.
... I wasn't sure how many cogs I'd need, but I think it's at least 4. 8 would be better. I put holes in for 16. Only one is shown here because it's a PITA to mate those in solidworks.
The magnets came in the mail today. Wish me luck!
Here's a brain teaser for you. Thermomagnetic motors have historically had terribly efficiency. This comes from a single common flaw. Can you figure out what it is? Email or comment if you think you've got it. Elizabeth.a.greene@gmail.com
