So it's not for a laptop.
I’m thinking vibrator.
“the lower energy density and increased operating temperature do not play a decisive role.”
ya because there are tons of energy problems demanding a lower energy density, higher operating temperature solution.
This is mostly a novelty of science, neat little piece of physics but not real practical in application.
Even the postulated battery use for solar or wind sound silly. The idea is make this huge warehouse to TEMPORARY store energy at a MUCH higher temperature.
Really? Who wants to maintain a large warehouse of batteries at temperatures of 200-400 degrees, and at that only as temporary storage.
“So it’s not for a laptop. “
The article says that twice. It says the market would be utility-scale storage.
A building full of batteries operating at 200 - 400 °C would have quite a cooling load. Moving that heat to the outdoors would consume a LOT of power. The cooling systems in large data centers would be nothing compared to the cooling systems for these battery plants.
thats 400 F to 750 F
