Wind power from the Sky
Wind power from the Sky
To harvest wind energy, you don't necessarily need rotors on steel masts - light kites on thin ropes can do the same. The Empa spin-off TwingTec has been researching this technology for some time now. Last autumn, it was possible for the first time to start, generate electrical energy while flying and then land again, all in the specified level of automation.

Hybrid overhead lines: More power, not more power lines
Social opposition to new high-voltage lines is delaying modernisation of the power grid. Two projects of the National Research Programmes "Energy Turnaround" and "Managing Energy Consumption" have determined the optimum design of hybrid overhead lines needed to increase the capacity of the power transmission grid and, at the same time, win popular acceptance for the new technology.

It works: Ultrafast magnetic processes observed “live” using an X-ray laser
In first-of-their-kind experiments performed at the American X-ray laser LCLS, a collaboration led by researchers from the Paul Scherrer Institute has been able to precisely follow how the magnetic structure of a material changes. The study was carried out on cupric oxide (CuO). The change of structure was initiated by a laser pulse, and then, with the help of short X-ray pulses, near-instantaneous images were obtained at different points in time for individual intermediate steps during the process.
