Northwestern University scientists have now developed a carbon nanotube solar cell (CNT) that is twice as efficient as its predecessors. Early research stalled when CNTs proved to be inefficient, converting far less sunlight into power than other methods. Yet the CNTs have long shown promise for photovoltaics because they’re lighter, more flexible, and cheaper than […]

Imperial College London researchers have engineered the harmless gut bacteria E.coli to generate the first renewable bio-propane fuel. The Brits development is a step towards commercial production of biologically produced fuel that could one day provide an alternative to fossil fuels. Propane is an attractive source of fuel because it burns cleanly, is easy to […]

A study by a team from the Institute of Vehicle Concepts, German Aerospace Center (DLR) on the total cost of ownership (TCO) strongly suggests car manufacturers should develop a modular battery design for plug-in hybrid and extended range electric vehicles (PHEVs and EREVs). That simple change would allow consumers a choice of storage capacity to […]
