WWF South Africa is hoping for more entries into its annual Climate Solver Awards. The competition is a chance to show off innovative technologies geared towards reducing carbon emissions and boost energy access. Entries to the competition are open until January 30.
One of last year’s winners was SolarTurtle. The brainchild of company Ugesi Gold, which operates out of Stellenbosch, the aim was to give people affordable electricity off the grid. Packaged in a shipping container, the container unfolds during the day to charge numerous battery packs via solar power. These battery packs can be taken to where they are needed to provide electricity to power lights or appliances. (more…)

The IEA said the cost of photovoltaic panels would continue to plummet, falling by a further 60 per cent for household rooftops and 70 per cent for power companies even after the dramatic gains of the recent years. (more…)

Scale a narrow ladder up the side of the motorhome, and a compact rooftop solar farm comes into view. Photovoltaic panels adorn the top, and even the front hood.
They are linked to a series of batteries that help distill and cool water for drinking. Excess water and power feed an evaporative “swamp” cooler that keeps the cabin comfy.
