We’ve been treated to some bold concepts and big reveals like the Porsche 918 Spyder and BMW i8 at this year’s Internationale Automobil-Ausstellung (aka Frankfurt Motor Show). Now after dashing through downpours and dodging crowds in the multiple halls at Messe Frankfurt, it’s time to round-off our coverage of this automotive hardware spectacular with a look at some of our other favorites from the around show floor. While this is essentially a photo tour of…"Frankfurt Motor Show wrap-up :: 2013"
Researchers at North Carolina State University have developed a new system for strengthening the connections between stacked solar cells which could improve the overall efficiency of concentrated photovoltaic technology and reduce the cost of solar energy production. The hardened connections could theoretically enable these cells to operate at concentrations of up to 70,000 suns while minimizing wasted energy. Stacked solar cells are made up from several solar cells that are stacked one on top of…"Thin films of gallium arsenide appear to reduce energy loss in stacked solar cells"
First of all, the 2X4 is indeed a hauler. It can schlep up to 100 lb (45 kg) on its front-located cargo bed. According to NTS, the way in which the load is centered over the 24-inch front wheel – along with its patented steering system – allows for “the best possible balance, handling and maneuverability in tight urban environments.”Cargo bikes are nothing new, nor are electric-assist bikes, nor even two-wheel-drive models. NTS Works’ 2X4…"The 2X4 Cargo Bike, in all its stuff-haulin’ glory"
