What's the old saying; great minds think alike. I loved the video. You could see pulses of bubbles being ejected from the nitinol as it contracted. In my rig, I had the nitinol vertical and when it would contract it would pull the lever arm of a weighted fulcrum up, I was later going to use to try to calculate the force. I burned through just about every filament I had. It was a good lesson in hydrogen embrittlement. It's still not a bad idea, but we just need a material that doesn't get brittle after hydrogen or deuterium loading. I'm clueless as to what that would be.
