ISS's radiators. It's processing data on the station that would otherwise be transmitted groundside and processed here.

They get to claim it because we let them. Every time an article comes out with "____ is a Nazi dogwhistle," there's a set of people who don't want to be associated with Nazis (or insert relevant disliked group of choice) who will immediately drop whatever the thing is. This creates a cycle where something does eventually become a dogwhistle, because everyone who didn't use it as such has stopped using it altogether.
TL;DR: Fuck 'em. Don't let those assholes control how you express yourself.
Or that everyone else is just as horrible as they are, so they'd feel justified in being a sloppy fart of a person.
This is bullshit. I've been staring at it from every angel. They'res no hippo in this picture.
Your friends are constantly spewing EM radiation at you. So is your home. The trees outside. The very sky. There's no escape. Even if you were to enclose yourself in a Faraday cage and exist in complete darkness, your own body would still be bathing your surroundings in EM radiation that bounces off the cage.
I live out in the countryside. The nearest store is about 2.8km away. Put on some good music, get an ice cream for the second half of the trip, it's a lovely walk. I could catch a bus back, there's a stop right by the shop, but my timing is generally shite. If I'd be halfway home by the time the bus comes, I'd rather just walk.
They're not producing fuel to continue the same reactions, which would be a violation of conservation of energy. They're producing fuel to run a different reaction. Less "perpetual motion machine," more "spinning a turbine to charge a battery to run an EV."
Edit: A better analogy is cracking water to capture the hydrogen, to later burn it in a fuel cell.
A Deuterium-Deuterium reaction produces Helium-3 and a neutron, or Tritium and a proton. Roughly even odds on which products you'll get. And a ton of energy. A Deuterium-Tritium reaction produces Helium-4, a neutron and a shitton more energy.
Basically, the DD reaction is used to create fuel for a more predictable and energetic reaction. From the article, seems they're also bombarding Lithium with neutrons from the DD reaction to create more Tritium. Problem with Tritium is that while it does occur naturally, it's extremely rare and volatile. Tritium has a half-life of about 12 years, so if we want to use it in a fusion reactor, we need a feasible way to produce more of it at scale.
It's all stepping stones to a greater goal though. DD and DT reactions produce neutrons, which will make your entire reactor highly radioactive thanks to neutron activation. D-³He and ³He-³He reactions produce ⁴He and protons, which are actually able to be controlled by magnetic fields and won't irradiate your whole shit. But then sourcing ³He becomes your new biggest problem.
Hats off to my man MrEdders. Yes, I'll absolutely watch your three hour video on some obscure 90's FMV noir game!
Since you were so insistent that it's simple, I told you to go and implement non-rigid capes to two old games that never had more than a rudimentary physics engine, and report back just how easy it was. And seeing how your reply, three minutes later, started with the words "Already done," I can only assume that you did it. So do tell, how easy was it?
What power do you have when there's no one to subject to it?
