The Saphonian bladeless wind turbine draws inspiration from the design of a ship's sails

Bladeless turbine claims to boasts impressive efficiency at low cost

Tunisian green energy startup Saphon Energy has created a new bladeless wind turbine which draws inspiration from the design of a ship’s sails, and promises to convert the kinetic energy of the wind into electricity at up to double the efficiency – and half the cost – of a typical wind turbine.

Dubbed the “Saphonian,” in honor of an ancient wind divinity worshiped by the Carthaginian Mediterranean culture which predated modern Tunisia, the current iteration of bladeless wind turbine is the second prototype developed by the company thus far.

The Saphonian turbine implements a patented system called “Zero-Blade Technology” in order to harness the wind’s energy. This is said to involve channeling the wind in a back and forth motion, until it is converted into mechanical energy using pistons. The pistons then produce hydraulic pressure, which can be instantly converted to electricity via a hydraulic motor and a generator, or stored in a hydraulic accumulator.The savings in manufacturing result from being able to discard the blades, hub and gearbox needed in a traditional wind turbine, according to Saphon Energy.
