I was watching live, on the NASA spacefight stream, (I only do it for the 3 hours of flarestack action you know), and to me, the commenters on the stream, and indeed Scott Manley in his latest YT vid, the explosion looks more like it started in the region of the ground support system, the pipes and cables that connected SN4 to the rest of the world. I didn't see any signs of structural collapse in SN4 at all.

Hmm, now I get it. Sorry, I've been away.
But now I'm waiting for the picture on the next story of a giant red robot, that instead of the article when clicked on takes you to a recording of the cover version of Starfleet, (80's anime redub, sorry I forget the name of the original series), performed by Brian May and Eddie Van Halen.
I think my copy of the 12" is filed next to my geek card...
Re: "most people hate having to mess with their heating controls"
"...get the price down to the point where even someone renting can get their money back in a year (a typical rental period) and even take their smart valves with them, putting back the originals before they go..."
Oh, to live in that tech bubble with rainbows and unicorns. Get real.
So what landlord is going to let a renter fiddle with the central heating system to fit new valves, let alone the cost of getting a plumber in to drain and refill the system when the valves are installed or removed? Then there's there the connection to the boiler the controller needs. That's assuming the boiler even has the appropriate connections, most rental properties are lucky to have a boiler newer than about twenty years old. And the fact that most renters are on or about minimum wage. So they might save £100 over a year, not much point if they don't have a spare £100 to start with to invest.
I could go on, but I won't. Instead, I'm going to put a jumper on as I can't actually afford to turn on the heating.
"..Alexzpro's generator is a small compound steam engine... "
Don't think so. A compound uses exhaust steam from a high pressure cylinder to drive a lower pressure one. This means the low pressure cylinder is bigger than the high, and both look the same to me.
Now, some may say that they could be bored out to different diameters. True, but it looks like the exhaust runs from both cylinders, not just one as would be the case with a true compound.
Oh, and it does look like a reversing gear to me too.

Haven't had time to read through all the previous comments, but true boffinery should involve a certain amount of "Shed-idity". This could be an institutional shed, like the Bletchley Park huts, or domestic, Barnes Wallis building catapults at home come to mind. It probably also involves a certain amount of sticky tape, and possibly string as well.
Re: The ultrasonics bit sounds like utter cobblers to me.
Exactly. Most PC speakers roll off around 18K, and of those that go higher, it's mostly distortion so I doubt you'd get any significant bandwidth. Then, you also have the fact that most cheap mic capsules as fitted in PC's roll off at about 15K...
"...an extraplanetary body came down over Canada around 12,900 years ago, possibly trigging the death of the giant animals then roaming the North American continent and starting a cooling spell that helped drive mankind towards agriculture and civilization."
Hmm, a giant alien body wandering North America. Cthulhu?
