Basically a plastic bucket with a fan grafted into the top which
blows air
over a block of ice to produce cooler air.

Thus evaporating more moisture into the air, increasing the humidity
and nullifying any benefit of the reduction in temperature!

Not if the air is dry in the first place. That is how evaporative
coolers work,
what the yanks call swamp coolers.

Yeah, because it feels like you are in a swamp if you use one.
If the air is dry then a fan will keep you cool using your own sweat.

How are you t'day Rod?
