Paint can swamp cooler

This was an attempt at making a small traveling swamp cooler for a vehicle without air conditioning.

The fan sucked air thru the small holes on the sides and thru the damp cloth wall lining.  A small fountain pump pushed water up to the round tube.

Multiple holes were drilled on the bottom of the round tube to disperse the water evenly on the mesh cloth.

Unfortunately my side of the mountain is humid, which doesn’t help for evaporative cooling. Plus the pump was powered with house hold current (AC) instead of battery current (DC). I couldn’t find a DC pump, but

it was a noble attempt.
