Would we be able to operate a 1/2 hp table saw ? I get some pretty good wind on occasion, which is why this idea arose. But, I'm sure there ore other places where this makes more sense. My 3/4 hp compressor produced a lot of heat, especially on humid days when lots of water was condensed. In certain locations, the ability to take water from the air might be quite valuable.
Here's an industrial site where they talk about heat reclamation from compressors. We'd want to go closed loop with rust inhibitors. Some systems use city water and then run it down the drain. Better systems use it to heat the factory and/or to heat water. None of the industrial sites consider condensed water as anything useful.

It was reportedly very hard to get enough water out of the compressed air to stop icing up in efficient motors. Inefficient motors form heat with the wasted energy, preventing icing. At least that's what I remember him telling me.
