> 45 C is not _that_ hot for a black box in the [insert warm place] heat during summer
I've been in a major city that would benefit from power backups like this. The hottest day the all-time heatwave was 45.2 C. So yes it's provably a reachable temperature, one where you _really_ want the aircon to work, and not lose the power.
Toyota's vehicles there have a reputation for being affordable, rugged and long-lived. And mass-produced. So the Tesla Powerwall may be a nice Proof of Concept - if you can afford it, if you can get one, but if Toyota is also in that market, well that's a different ballgame. Far more people will pay attention. All the same, I would wait a couple of years, see if the V2 is much of an upgrade.
“To measure outdoor air temperature on land, the setup is simple. A thermometer is placed inside an enclosure […]. Regardless of the shape, the enclosure is white in color to reflect solar radiation, which heats the thermometer and keeps it from getting an accurate air temperature reading. The enclosure also typically has slatted sides to allow air flow, and a double roof (a roof and a raised roof over that) to protect the thermometer from rain and further resist the influence of the Sun.”
So, they measure temperature in the shade, away from the ground, under a roof that’s painted white.
In the sun things can get hotter. 45 C water for a few seconds isn’t painful, but touching the hood of a black car or the asphalt on a road surface on a 40 C day immediately is.
