OOI, have you ever seen or used a cooler box that works by the

I'm aware of cheap air-con units that use that principal and I've used
/ made my own impromptu ones for some milk or beer when camping but
I've never seen a commercial one. Not saying they don't exist ...

evaporative coolers are well known technology.

Yes, I know, but we are talking specifically about 'evaporative
cooler boxes' here. Have you ever had / seen one?

Yep, they used to be almost universal here
before better ones became possible.

The amount of cooling is limited.

They also use it to cool the air near fountains and
my mate had an electric fan that sprayed a mist of
water into the air in front of it and that worked ok.

You can still buy those.
