Conceptual drawing of our dual-kite airborne wind energy system in an alpine landscape.
AlphAnemo is an Airborne Wind Energy startup based in Switzerland. With a young, dynamic team, the company aims to achieve what nobody else has reached so far: establishing highly cost-efficient flying wind turbines on the market to boost the global transition to green energy.
See below: Jean-Sébastien "JS" Brouillon in a Youtube-style explanation of the current prototype.
