Ford using liquid battery coolant in electric cars

Bloomberg BusinessWeek -- Ford says its Focus Electric compact car, which comes out late next year, will use cooled and heated liquid instead of air to regulate the temperature of its lithium-ion battery.

Johnson Controls can probably make the batteries, but not at a price that the sharp-penciled accountants would like to pay.

We're transferring the technology faster than you can blink your eye. Last seen on the WSJ two days ago, no American company can make the glass panels for a building in the USA. The only company that can make it is China!
