The jury is still out on whether hydrogen-fueled cars will be a competitive alternative in the future. BMW still seems to think it will be. Honda hasn't given up on its FCX Clarity hydrogen car either. Cities like London are laying the preliminary groundwork for a network of hydrogen filling stations. And then there's Ahhhnold and his hydrogen highway.
Researchers at the Massachusetts Institute of Technology have been looking at where the bottlenecks are inside lithium ion batteries that limit charging and discharging rates learned some interesting things. Lithium iron phosphate chemistry is particularly promising in terms of high charge and discharge rates. They found that some new processes for manufacturing the lithium phosphate coating on lithium iron phosphate crystals could provide for better access to the lithium ions allowing them to m
According to Reuters, a group of researchers at Massachusetts Institute of Technology are working on what they think is a more logical ethanol solution for our impending fuel crisis. Instead of using ethanol as a primary fuel or an additive, we could potentially see more realistic fuel-saving improvements across a wider spectrum if we implemented a system on cars that injected ethanol in small quantities when the engine is under heavy load.
