IMAGINE Nelson Mandela Bay filled with small, silent wind turbines and solar systems – and no more reliance on Eskom.
That is the vision of a pair of Port Elizabeth engineers who have designed a “hybrid inverter”, the Renovo Power Solution, which they say could save consumers millions at the same time as saving the world.
Wiegand von Hasseln and Trevor van Onselen have launched a series of public seminars to publicise their invention which they say is “the first energy system mix, manufactured and available for the open market, of its kind in South Africa”.
It is also the cheapest, they say, because the price of R2279 a month, paid off over five years, for their 1kW system, matches the cheapest wind turbine so far produced – and they are adding a photo-voltaic solar panel component. And from that price you can also, each month, subtract your current electricity bill.
