[Martin Fasani] has set out to build a beautiful low power E-Ink Calendar he can hang on his wall. But perhaps more importantly, the work he has done makes it easier for everyone in the future to have a e-ink display. Many battery-powered e-ink projects connect to some server, download a bitmap image, display the new

New co-authored paper demonstrates potential ten-fold energy density increase over existing lithium-ion battery technologies. Scientists from Honda Research Institute have collaborated with researchers at California Institute of Technology(Caltech) and NASA’s Jet Propulsion Laboratory to develop a new battery chemistry that enables the use of materials with higher energy density and a more favorable environmental footprint than current battery technologies. The
