Siemens Energy has uprated its D3 onshore platform wind turbines. The new SWT-3.2-101, SWT-3.2-108 and SWT-3.2-113 machines feature improved performance from 3.0 to 3.2 megawatts (MW) and implement the sum of design and operational experiences. The uprated products will enter serial production by the end of 2014. They will be available with 101 and 108 meter rotors for IEC class IA sites, and a 113 meter rotor for IEC class IIA sites. The 3 MW version will remain available for project sites with lower wind speeds.
Simplicity and efficiency were the key words when Siemens developed its first commercial direct drive turbine in 2009. Following five years of experience and a large number of D3 wind turbines installed worldwide, the fundamental approach remains the same, but the technology continues to be refined. The uprated Siemens D3 wind turbines represent a classical wind turbine evolution, combining the reliability of a proven and tested concept with cutting edge technology development. Improvements in the turbine control system and increased efficiency through the use of stronger magnets are the key factors that allowed Siemens to get more power out of the D3 drivetrain.
The uprating underlines the structural reserves already found in the construction of Siemens' gearless wind turbines. "One important goal of our development work is to utilize innovation to further tap the technical potential of our products," says Henrik Stiesdal, CTO of Siemens Wind Power. "Rotors, structures and performance have been tested intensively to simulate more than 20 years of lifetime stress. This resulted in a new product generation which offers the reliability of the predecessor while delivering up to 4 percent more energy yield."
Wind power and the associated service activities are part of Siemens' Environmental Portfolio. Around 43 percent of the company's revenues are generated by green products and solutions. That makes Siemens one of the world's leading providers of eco-friendly technology.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
