I was about to say, I've put together devices in minutes in front of my students that can convert electricity in the copper wire into infrared light then back into electricity on a different copper circuit and then into sound waves, light to electricity should be pretty doable.

Four of the five I saw while working as a ranger in the Tetons. One time, early in the season, I thought I saw wolverine tracks in the snow on a hike, but I realized they were too small to be wolverine, though too large to be weasel. It was probably a marten or badger.

This is why I made my own variation of the recipe, and typed it up, so I can check it on my phone 17 times while baking without taking anything out of the trash...then I have to clean my phone off.

I have some, but I won't share them, because I already used them for my kids.

It's a good thing there are people out there willing to donate bees, otherwise how would Elon Musk be able to afford them?
But in all seriousness, what the hell would we even do with bees on Mars?

Except the REALLY bad ones circle back to being easy, but then it's just depressing that they couldn't even muster partial credit. Of course, my students' proposed solution would just be to give everyone 100%...
