'Infinite singularities' sounds like the physics equivalent of 'two wrongs make a right'. Jokes aside, this is a really accessible post for non-optics experts. More science communication should be written like this. Kudos.

A lakeside house with a butterfly roof. The house is a simple box, but had some interesting details like a bridge and large windows.
View of the entranceway if the house, which immediately looks out to two large windows.
House is starting to look fancy. Next it gets a 3" spray foam sweater on the outside, a #buildingscience good practice.

Don't worry about it, Patton. That staining on the sill implies some is/will be rotting away on the inside. They plants will breath just fine through that moldy opening.

Structural cross section of a wall and floor showing a 40 mil underlayment between a concrete slab and the sub floor. This would have been perfectly fine as-is but the addition of spray foam below would prevent the osb subfloor from releasing water vapor.
Literal hours were spent explaining why we cant have a vapor barrier between the slab and subfloor after deciding to flash and batt in the crawl space. It's very easy to screw this stuff up.

Sell Sheet of Chiltrix CX34 air-to-water heat pumps. These units have a cooling COP od 6.52 and heating COP of 3.92.
Thanks, Philip. Looks, I'll be installing a couple of these next month. Theyre among the most efficient AWHPs on the market. I'll buy you guys dinner if I average anywhere close to the stated COPs on the sell sheet.

Most boilers sold today are .90-.95. That 5-10% loss wouldn't get you to 4. I guess my point is it's perfectly fine to say even on its worst day a HP is 2.5x more efficient than a top of lin gas boiler on its best day. Overselling just makes customers sad.

Look I'm glad heat pumps are popularizing, but can we stop overselling the COP? While 4+ COP happens, Most HE units operate between 2.5-3 efficiency, even lower in colder climates. Thats still a win without giving deniers talking points about how green tech doesn't live up to the promise.

A pitbull sleeping on the couch with his owner and a white lab. The pitbull has his paw covering his owner's face, as if to say, 'smell what I got into outside'.
I'm glad that my new dog respects me and understands who the master of the house is.

It definitely is cool, but its worth mentioning all of the issues documented on the voyage in this article. Ship replacement is only part of the decarbonizing shipping.

My lab did this with our new rescue. I would yell loudly to get her attention and then say no. Yelling gets their attention, no reinforces the bad behavior. Took a few days, but she changed he behavior. Positive reinforcement should work for the inverse too ( praise when resource is shared).

The ELT doors have moved for the first time. This was no small feat, as each door will weigh 650 tonnes once completed.
The ELT dome & its doors will guard the telescope from the harsh conditions of the Atacama Desert.

To be fair, I was anti-R290 until last Friday. Granted, all it took was a 30-minute conversation with someone smarter than me about propane refrigerant. I think Grenfell spread some pretty sticky misinformation.
