The “Skilift Tenna” (GST) cooperative opted for technology from Siemens’ Industry Automation Division to modernize its drag-lift.
Since its commissioning in late 2011, the solar ski lift has produced three times more solar power than that required to operate it and has doubled the number of people it can transport.
The 460 meter long drag-lift is located at an altitude of 1644 meters in the holiday resort of Tenna and required refurbishing after 40 years in operation. To achieve this, GST opted for a combination of a photovoltaic system and automation.
The newly installed photovoltaic equipment associated with the drag-lift is based on a solar wing system, whereby 82 photovoltaic modules forming socalled solar wings are hung between two ropes and automatically track the position of the sun.
The system produces a total power of about 90,000 kWh per year, two-thirds of which are fed back into grid at market prices, using Sinvert PVM string inverters.
The draglift’s operation involves a significant number automation components. A Simatic S7 programmable logic controller, enhanced with a fail-safe CPU and ET 200S modules, control the ski lift‘s operation. The refurbishment made it possible to double the hourly transport capacity to 800 persons.
The exchange of data between the lift’s mountain and valley stations is also based on Siemens technology, using an IM 151-3 interface module from the ET 200S distributed peripherals range.
The entire ski lift system in Tenna is operated using a Simatic Touch Panel.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.
The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
