Either GP poster is very, very tall (and can't breathe up there), or he's probably getting only about 300 W/m2 or so.

At that level he could be on Mars near the equator, and it’s hard to breathe there, too.

Interesting, so Mars' surface level insolation is similar to Earth's surface-level insolation, due to having less atmosphere? That makes solar power - and the Sabatier process - seem more feasible that I initially thought. I understand that Martian orbiters do require much larger solar panels than terrestrial scientific satellites with similar sensor packages.

I was researching before posting and I think I saw something like 40% in a paper, which is much more than the naive 25% you’d get at 2au.

But for things like heating, latitude makes a big difference. I did some calculations for a fanfic I wrote, and at a moderate 30°N or so, you basically get the same insolation as Rovaniemi in Finland assuming similar atmospheres. No wonder those characters never got sunburns.

Other humans. I feel disgust just remembering that particular event and won't share any more details. Sorry. My point was only that I had a really really nice office but preferred the hot and noisy radio lab strongly.

Oh ok, that was pretty random. Yes, work where you feel you can be productive and happy.

For the record: he left that place shortly after.

No it's not. To amortize is simply to spread the cost over time. That spreading may come with its own costs, like interest, but that is not an essential component of amortization.

TY! TIL

You are welcome. :)

Average UK indoor temperature is about 17.5c-18c apparently so hardly freezing. A bit chillier than I like in my office. Personally in winter I heat my house to 14c as a minimum, 20c in the living room and office. Reason being I only need warmth if I'm sat down and not moving, so any higher and I start to get too hot.

For the last 20 years "helpful" people have been saying "reduce your thermostat by 1 degree to save on your energy bills" My temperature is now approaching absolute zero.

You must be living in interstellar space.

The thing is 17.2 C is ok with good insulation and really cold with bad one. (so is 20 C for that matter)

In this context, do you mean 17.2C on the thermostat or as measured room air temperature?

Preferably the measured room air temperature.
