isothermal

Only if the heat is discarded and you reheat with fuel do you benefit from isothermal compression.

Getting the satellite overall to an average 27C temperature doesn't necessarily keep the GPU cool; the satellite is not isothermal.

In practice, this means we need to pump a lot more fluid, too, to keep a larger thing close to isothermal.

Assuming isothermal compression (which would be a nice ideal case and is not easy to achieve unless one compresses very slowly), the work is nRT • ln (volume ratio).

Compression is nice because practical isothermal compressors are now being demonstrated.[0] Both liquefaction and compression require cooling.

If you use water to compress the air as it goes down, you get isothermal compression.

Some, like isothermal membrane-based air dehumidification, could be 4x more efficient than existing vapor compression dehumidifiers.

Nice article: This profile closely matches the expectations of a singular isothermal sphere profile where....

Actually, if the compression is isothermal (and it's an ideal gas), 100% of the energy from the grid is turned into heat, and the energy state of the air is constant.

My main question is: Did the number of photons stay constant throughout the isothermal compression?

Instead one might try to approximate isothermal compression, perhaps by using multiple stages with heat exchangers to adjust the temperature between stages.

It's true that an isothermal process is a reversible process, and isothermal air compression is therefore a great way to get high efficiencies, but compressed air just doesn't seem like it will scale well.

It's quite interesting because the first hypothesis "isothermal atmosphere at the same temperature as the ground" show exactly hw climate change doesn't work.

Isothermal expansion (T) The amount of energy out/energy in is T_h/T_c = 1.
