The transportation authorities are now planning to operate two lines exclusively with eBuses by the middle of 2013. During the Skiing World Championships in Schladming, Austria, one of these electric buses transported around 6,000 passengers and logged more than 1,000 completely emission-free kilometers.
Using this recharging technique it is possible to install a smaller battery system and at the same time save on investments in infrastructure. And thanks to their regenerative braking systems the electric buses can also recover energy. As soon as the driver takes his foot from the accelerator the energy recovery system is activated.
The drive system in these buses is significantly more efficient than a conventional diesel powertrain. Nine lithium iron phosphate batteries with a total capacity of 96 kilowatt hours supply the motor - through an IGBT power inverter that converts direct current to alternating current - with enough energy for up to 150 kilometers.
The batteries supply not only the drive system but also all of the onboard electronics, the heating, and the air conditioning.
Electric buses make a crucial contribution to protecting the environment and make our inner cities better places to live - and at the same time they have lower operating costs than diesel buses.

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.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
