I had a Mozart "for concentration and study" vid running in the background on YouTube, when an advert for Radiant Tank Top Heaters by Global Industrial came on.
Definitely not the kind of thing I normally expect, but I got curious, and once I saw the images of "propane tanks with laser dishes" my mind went running all over the place. These things seem really dangerous, but also very practical. I can see every dude-bro's garage workshop with at least one of these, and if I was out in that shop on a freezing-ass cold day, I'd be parked next to this thing, because I'm tough, but still smart enough to stay warm.
My first random thought was the Star Wars laser dish cannons. I loved Empire Strikes Back, and always thought these things were cool in a totally impractical kind of way. I love that Lucas and his people always seemed to let their imaginations run wild. I mean, just because WE think it might be impractical doesn't mean some other galaxy-spanning civilization wouldn't build it anyway, right?
And, finally, my mind went a bit more literally "tank top heaters"... because, you know, I've been there, when those bikini tan lines can be a bit embarrassing...
Meanwhile, you're laughing, and that's the whole point of the exercise. ;-)
