Exhibitors: Pocketful of Sunshine

Sep 11, 2014

Sunlight is possibly the most plentiful resource available to us in the southern hemisphere – and it’s free! These Exhibitors show us some of the ways in which solar power can be harnessed and used in the home:


Mark Blumenthal’s Solar Bottle is a low-cost, modified water cooler bottle with a black painted tin can which acts as a passive solar heater.

Deon du Preez’s Solazela, on the other hand,  is a high-pressure solar water heater made entirely from recyclable plastic material – providing a household with over 125 litres of hot water per day.
