I wasn't sure where to post this, but it seems it may have a use in the growing community.

"A thin film coating can chill a vat of water to 15F cooler than its surroundings, by absorbing---and then emitting---the sun's infrared rays."

I wonder if this would also work on inside grows. Who wouldn't want their DWC buckets 15F cooler!?
