Power/Performance Bits: Mar. 20


Proton battery prototype A team at RMIT University built a prototype rechargeable proton battery combining hydrogen fuel cells and battery-based electrical power that has the potential, with further development, to store more energy than currently-available lithium ion batteries. The working prototype proton battery uses an activated carbon electrode for solid-state storage of hydrogen with... » read more

Harvesting energy from multiple sources Researchers from the University of Oulu in Finland found a particular type of perovskite, KBNNO, has the right properties to extract energy from multiple sources simultaneously. While perovskites are particularly known for their use as solar cells, certain minerals in the perovskite family show piezoelectric and pyroelectric (harvesting energy from ... » read more

Mimicking roses for solar Scientists from the Karlsruhe Institute of Technology (KIT) and the Center for Solar Energy and Hydrogen Research Baden-W├╝rttemberg (ZSW) reproduced the epidermal cells of rose petals and integrated the transparent replicas into an organic solar cell, with an efficiency gain of 12%. The epidermis of rose petals consists of a disorganized arrangement of densely p... » read more
