TwingTec is developing drones that can harvest wind energy at a height of several hundred meters and has gotten a label from the Solar Impulse Foundation.


The Solar Impulse Foundation, which was established by the space pioneer Bertrand Piccard, recognizes financially profitable, environmentally friendly solutions with the Solar Impulse Efficient Solution Label. This serves as a type of quality guarantee that is internationally recognized. The label is designed to advance clean developments more rapidly.

In March, the Solar Impulse Foundation awarded its label to two companies. According to a press release, one of these firms was TwingTec, which is based in Dübendorf. The spin-off from the University of Applied Sciences and Arts Northwestern Switzerland (FHNW) and the Swiss Federal Laboratories for Materials Science and Technology (Empa) is developing a new wind energy system. For this, a drone is used which travels around its orbit while being pegged to the ground by a connecting rope. The wind is converted into electricity by a generator on the ground via mechanical transmission.

Alongside TwingTec, DEPsys from western Switzerland was also awarded the label. The company has developed a control platform that allows grid operators to monitor their electricity distribution network.

According to an article at startupticker.ch, a total of five Swiss firms have now been awarded this label. In total, 1,000 labels have been issued to companies around the world in several different phases.
