The so called flow battery has long been considered as a likely candidate for storing intermittent renewable energy. However, until now the kinds of liquids that could produce the electrical current have either been limited by the amount of energy … Weiterlesen …
Hydrogen, a concentrated energy source that can be stored for long periods and transported over long distances, has emerged as the fuel-of-choice for fuel cells and fuel cell vehicles. Its other advantages are that it can be generated with renewable … Weiterlesen …
Solar cells, LEDs and detectors made of organic and hybrid semiconductors can nowadays be simply printed out, even together with teensy nanostructures that make them function better. The development of low-cost printing methods for electronic and optoelectronic components is at … Weiterlesen …
A wearable energy-harvesting device could generate energy from the swing of an arm while walking or jogging, according to a team of researchers from Penn State’s Materials Research Institute and the University of Utah. The device, about the size of a wristwatch, produces … Weiterlesen …
A team of semiconductor researchers based in France has used a boron nitride separation layer to grow indium gallium nitride (InGaN) solar cells that were then lifted off their original sapphire substrate and placed onto a glass substrate. “By putting … Weiterlesen …
Emission-free, energy-efficient and low-noise? Battery-operated trains could be an important component of sustainable mobility. Thus, some companys are currently conducting research on this field; one of them is Bombardier Transportation in Berlin, Germany. The new battery-operated Bombardier Talent 3 electro-hybrid train is … Weiterlesen …
The Sun contains 99.8 % of the mass in our solar system. Its gravitational pull is what keeps everything here, from tiny Mercury to the gas giants to the Oort Cloud, 186 billion miles away. But even though the Sun … Weiterlesen …
