The original electric cars, a solar-powered train tunnel, and geothermal energy harvesting that also sequesters carbon… your green tech finds for the week.
Big battery breakthrough?: Researchers at MIT are redesigning batteries as “semi-solid flow cells,” which could eliminate charging time issues for electric cars, as well as provide viable storage of energy generated from renewable sources. (via Grist)
Solar-powered train tunnel opens in Belgium: A two-mile stretch of train tunnel near Antwerp is now covered with solar panels, and will provide electricity for both high-speed and inter-city rail links, as well as a train station. (via AOL Travel)
