actually the phase transition from ice to water is 80 calories per gram
whereas the
transition from liquid to gas is 540 calories per gram.

better to spritz the water up into the air and what falls back is going to
be a lot
cooler. best is shade cloth, like 70% or lilies that float and block the
sun.
actually, a piece of styrofoam that blocks the sun works too. Ingrid



That assumes that the humidity level is low enough to support evaporative
cooling. Presumably the waterfall and other water circulation features
already maximize the evaporative cooling potential.

Reminds me of what one of my profs used to say. Try both, see what happens,
then report back to us.
