The ancient civilisation of Carthage meets 21st century design in this wind energy convertor. The Saphonian is bladeless and non-rotating and can capture twice as much energy as a traditional wind turbine, say its developers. Tunisian start-up Saphon Energy took its inspiration from Carthage’s sailing boats of 2,000 years ago, as well as the movements of birds and fish. The result – an aerodynamic bowl-shaped sail and a wind convertor that follows a figure of eight pattern. Engineers say their design beats traditional wind turbines on performance and cost, making it ideal for off grid energy generation in developing countries like India.
