I found myself wincing at "pressure produces heat". For the purpose and context of this article, that is probably close enough. Because the subtlety of energy spent increasing pressure being converted to thermal energy is too finicky. But it's also more correct. And this relates to a problem I've run into whenever you try to talk to an expert about something. People come up to me with fanciful ideas about physics and you have to stop them every five seconds to clear up what they mean by "power" or "energy". Or (as a favor) just listen all the way through and see if you can get a notion of what they mean so you can discuss their idea. Same thing happens when I try to ask lawyers about something. I'm always getting asked, "Do you mean a law, or a statute?" or having things like "well, that's a legal term-of-art" given back to me. The point being that it's hard to jump into thinking about anything that others have spent a long time considering and carefully defining.
