Heat lost to the water is lost. If you want to try to avoid that you need to save that heat energy after the compression stage.
- ncmncm 7y agoI see that you have not thought this through. Yes, some of the heat will not be recoverable, but controlled expansion of highly pressurized air creates a large temperature drop that would readily absorb heat from the ambient water.
