New lithium-ion process could lead to super fast charging, but still needs BIG pipe

Researchers at the Massachusetts Institute of Technology have been researching where the bottlenecks are inside lithium-ion batteries that limit charging and discharging rates, and they've learned some interesting things. Lithium iron phosphate chemistry is particularly promising in terms of high charge and discharge rates. Researchers found that some new processes for manufacturing the lithium phosphate coating on lithium iron phosphate crystals could provide better access to the lithium ions,

Top Gear US shows us how to perform a TDI engine swap

Top Gear US has struck again with their latest installment in the Project Sipster saga, and this one's a doosey. The TG crew is taking an early '80s VW Rabbit diesel apart and replacing the engine and transmission with newer and more powerful units. We're pretty sure that there's plenty more planned for the oil-burner than just an engine swap, so we'll be following closely over the coming weeks.

BMW cranks up the efficiency of hydrogen internal combustion engines

BMW has been active in the development of hydrogen as an automotive fuel for many years but they have taken a distinctly different path from virtually every other automaker. Instead of fuel cells, BMW has stuck to internal combustion engines and, rather than compressed gas, it has used liquified hydrogen. The problem with the former is that gasoline and hydrogen have very different combustion characteristics and engines designed primarily for gasoline operation lose a lot of power and efficiency

What are some advanced battery basics for beginners?

Electric cars have been with us since the very beginning of the automobile age and from that time until now, its most important component has been the battery. It stores energy chemically until it is needed to create the electricity that powers a vehicle's motor. There have been different types of batteries over the years but none have had the practicality or popularity of the very first rechargeable one, the lead-acid battery.

UK new car CO2 emissions plummet faster than ever

2008 saw the biggest drop ever in CO2 emissions from new vehicles sold in the UK, with a year over year reduction of 4.2 percent. Wtih a fleetwide average of just 158 g/km, cars amount to just 11.5 percent of total UK carbon dioxide emissions. The combination of rapid escalation in fuel prices in 2008 and congestion charges in cities like London undoubtedly pushed many car buyers to some of the low emissions specials like the
