What about a recirculating fountain to spay the coils in my ac
condenser for 90+ temp days.

I pumped rainwater water up from a plastic 55 gallon drum through
a horizontal tube with some holes over the coil of a window AC.

How much 'gain' in efficiency would result?

... 20% in my experiments and 22% in Y. Goswami's U. Florida central air
experiments. He built a swamp cooler around the AC coil, so the water
never touched it. I avoided mineral buildup by using rainwater, with
a $10 10 W fountain pump in a plastic 55 gallon drum below the AC.
Limestone in the drum helps avoid acid rain problems.

Some thoughts.

The average house unit in Florida is several tins ad it produces about
1 gallon of cool condensed water per day HMMM?

Some details please on the swamp cooler design.

Would this idea work?

Sink a 55 gallon drum into the 70* ground to cool the water and to
hide it.

Pipe all condensate into the drum.

Swamp cooler surrounding the condenser.

I have a duplex on an island.

The utilities last month were almost $700.
