Solar irrigation product converts sunlight directly into motion
The invention converts energy produced by PV cells directly into mechanical motion without batteries or power electronics. Its developers claim the solar motor can drive irrigation water pumps and ventilation turbines for more than 20 years without maintenance. Auxerre-based start-up Saurea has unveiled an electric motor technology that converts solar energy directly into mechanical rotation. The company’s first product provides rotary motion able to draw water for agricultural irrigation and to supply fresh air to ventilate buildings. “It’s the first solar engine in the world,” said Isabelle Gallet-Coty, one of Saurea’s founders. “It revolves entirely around renewable energy and has the particularity of never breaking down.” Perpetual motion Unlike conventional electric motors, Saurea’s technology directly converts solar energy to rotary motion without the need for power conversion components, giving the solar engine unusual resilience. “Electronic power conversion compon
