 We're trying to move away from fossil fuels to be more sustainable, but then we're using these rare earth materials in the electric motors of the EVs. And so I wanted to figure out a way where we could have electric car motors that don't use the rare earth materials and would therefore be more sustainable. And I know there are designs out there that don't utilize the rare earth materials like the synchronous reluctance motor, or I ended up going through 15 versions of my motor before getting a successful prototype. So I'd say kind of like learning it all myself through the trial and error was difficult because I mean, reluctance motors are pretty complicated machines as one would imagine. I made a pair of boots that allow me to run faster. It's kind of like a pair of stilts with this lever that bends and it stretches a bundle of speargun cords, which stores like elastic potential energy, allows you to run faster. And on the second version of those boots, I actually got up to 22 miles per hour with that machine, which is almost Olympic level running. So I thought that was a pretty cool project. Being the day when EVs are fully sustainable due to the help of something like my electric motor innovation, that would be a dream come true for me. If you walk along a river in any city, it's only in Paris where you get these stalls with wonderful books. We just saw something, a magazine, the fine magazine, of when we were born. So somebody kept this for 60 years, my goodness, wonderful.
