Empa spin-off TwingTec part of the Solar Impulse Foundation
Fresh Breeze for Ecology and Economy
Following the success of the ﬁrst solar ﬂight around the world, Bertrand Piccard and the Solar Impulse Foundation has launched the second phase of their action: selecting #1000solutions that can protect the environment in a proﬁtable way, and bringing them to decision makers to help them adopt more ambitious environmental targets and energy policies. So far, ﬁve solutions from Switzerland have received the Label including two that were nominated following the recent selection in March. We are proud to announce that the Empa spinoff Twingtec is now part of the #1000solutions lineup of the Solar Impulse Foundation.
Wind Energy 2.0
Promoting Wind Energy 2.0, Twingtec developed an innovative and sustain-able energy solution that unlocks the full power of the wind. Horizontal axis wind turbines have limitations which restrain both economically and technically their penetration potential. TwingTec ﬁlls this gap by offering a new wind energy technology which pro-vides key beneﬁts over wind turbines. TwingPower builds on minimal material usage (no tower and no foundation are needed), the compact and mobile units can be fast and easily deployed. Higher altitudes and stronger winds can be accessed as well as the strong off- shore winds in deep water, where the potential for Europe only is estimated to be 4 TW. TwingPower enables new sites for wind energy, higher capacity factors up to 60% and more reducing the need for storage and opportunity to reduce the levelized costs of energy of wind by at least a factor two. TwingTec’s goal is to speed up the transition to sustainable energy by unlocking the full power of wind, a key element of a 100% renewable world.
Metal 3D laser printing
Hot off the Oven
During metal processing in the 3D laser printer, temperatures of more than 2,500 degrees Celsius are reached within milliseconds, causing some components of the alloys to evaporate. While widely considered a problem inherent to the process, Empa researchers spotted an opportunity – and are now using the effect to create new alloys with novel properties and embed them in 3D-printed metallic work pieces with micrometer precision.

Circuits on all kinds of material
The Transistor out of the Printer
There is more than cool looks about hip clothing for top performance: Thanks to a variety of smart technologies, high-tech clothing today is capable of analyzing body functions or actively optimizing the microclimate. The basis of these novel textiles are “smart” fibers and biocompatible composites that also contribute to innovations in biomedical research such as sensors, drug delivery systems or tissue engineering.
