Solar Heating System with Water Battery

Water battery Dutch inventor Kees van der Geer sends us this paper and wants to know what we think of it. Comments are open.

“Heating with a sun collector costs nothing and contaminates nothing. In this article I propose a solar heating system consisting of a large solar collector, suitable for the heating of a house and a heat store, capable to bridge a week of cloudy weather. Both are made from simple materials.”

“Maybe a practical solution to make a heat store is to buy a inflatable swimming pool of 17m3 and construct an insulating box around it. “
