Somebody has to make the call. There was this dinosaur book for kids in a little free library. It didn’t even have an author or publisher, because it was AI garbage. Full of misspellings, etc. I contemplated throwing it in the trash because I don’t think it should exist. But for some reason I had trouble deciding that for others.
Digitize and delete? Scan straight to OCR and dump the books. One hard drive can store a lot of books.
I was just thinking about this. Love these videos. Cooling of a solar panel is a good application, as long as it gets cold enough for long enough to re-solidify at night.
An alcohol/NaCl solution with a stabilizer can make an ice pack that freezes colder than water. That could be used to keep ice cream frozen in an ice chest.
It would be cool to have recipes for a few different temperatures. There’s a German company Qool Products that sells PCM temperature elements (ice packs), at a variety of temperatures, to store ice cream up to red wine/cellar temp in their ice chest. With some trial and error I guess we could now make our own!
