Neue Nanogeneratoren können Energie aus der Reibung rollender Reifen gewinnen -

A group of University of Wisconsin-Madison engineers and a collaborator from China have developed a nanogenerator that harvests energy from a car's rolling tire friction. An innovative method of reusing energy, the nanogenerator ultimately could provide automobile manufacturers a new way to squeeze greater efficiency out of their vehicles. The researchers reported their development, which is the first of its kind, in a paper published May 6, 2015, in the journal Nano Energy. Xudong Wang, the Harvey D. Spangler fellow and an associate professor of materials science and engineering at UW-Madison, and his PhD student Yanchao Mao have been working on this device for about a year. The nanogenerator relies on the triboelectric effect to harness energy from the changing electric potential between the pavement and a vehicle's wheels. The triboelectric effect is the electric charge...
