Update: Working with Wikipedia on this. They pushed a new set of certs earlier today. There may be issues with some UAs. My old, stale Android (5.0.2) and Chrome (76.0.3809.132) aren't happy with Wikipedia or Globalsign's root test URL:

(Also an ERR_CERT_AUTHORITY_INVALID)
I suspect a stale CA list somewhere.

Thanks for the book, I'm adding it to my list
You may also enjoy How To Invent Everything[0], from the creator of SMBC Comics. The frame device is that it's a manual that comes with your time machine, only to be used if you get stranded. I thought it would be a fun flip-through but it's delightfully dense, with fun comments on when, where, and why you'd need want/need to invent something depending on "when" you get stranded in time. 0: https://www.howtoinventeve…

Mild sidenote: How to Invent Everything is by Ryan North, the cat behind Dinosaur Comics; Saturday Morning Breakfast Cereal is done by Zach Weiner, a different person.

No, it has been actually deployed and is commercially sold as heat recovery chiller. The problem is an much lower efficiency than compression refrigerators, some of which could be regained by tuning the liquids used in the system. That is not a problem when you're working with waste heat though. (E.g. solar thermal, recovery from solar concentrated, cogeneration, geothermal.) The other problem is that it has to be pe…
I thought this is how RV (propane) refrigerators work? Or, am I confusing this with a different, but similar system?

Love it!
It would be interesting to know the practicality of this fridge and its efficiency in relation to more conventional fridges.
Nope. It also requires a heat sink.

The practicality is answered by the fact that many/most recreational vehicles you see going down the road will use a refrigerator like this. As for power efficiency, in comparing compressor fridges to absorption, I think a well-design compressor fridge will use less electricity (absorption fridges can use an electric heater, too), but not by a huge margin. But if your efficiency question is about how well it keeps th…
But of course in the case of an RV where you are on a car battery but have a large propane tank, they make sense in terms of energy storage.
With the more cost effective Lithium batteries the higher end RV coaches have all eliminated the absorption fridges and gone with compressors and bigger batteries.

Milder sidenote: SMBC was created by Zach Weinersmith. Presumably his ancestors made the weiners.
