This is for Photrablogger’s Mundane Monday number 25.

I took this in 2005 at Lake Matinenda in Ontario. The solar panel raft charges a battery that in turn powers a pump to fill a hot tub on a cliff about 12 feet above the water. It is a box with a custom pond liner and a propane pool heater. The raft was deployed each summer.

This year the solar panels are moving to the roof of the cabin….. no more raft.
