- I know this has no relation at all to the hobby, or radio or gear.. but I just read it and thought it interesting enough to post here anyway. It's a great story.
3 teens invented a salt-powered refrigerator that doesn't need electricity. They're building 200 of them for hospitals to use.

The invention uses salts that pull heat from their environments when they dissolve in water.

They won the 2025 Earth Prize of $12,500 and plan to test 200 units in 120 hospitals

Agree, great story. Amazing how things get invented. TV was invented the same way, by a kid(teenager) who discovered the way to transmit video.
There was a couple of girls that invented making plastic from fish waste that would biodegrade after a time.
It's OK we can divert from part 15 a bit.

I haven't watched the video yet but I never heard anything about a teenager being the inventor of television!
