Fast juicing electric cars

This Porsche 914 has been converted to run entirely on batteries as part of a research project at MIT, giving it an equivalent mileage of about 160 miles per gallon. Now, mechanical engineers have started working on a second project, using a Mercury Milan donated by Ford, to build fast-charging stations for electric vehicles. The goal is to design a high-voltage charging station that can charge a car's batteries in 10 minutes.
