A Laptop in Every Garage
The emergence of small lightweight long-running lithium-ion batteries has helped create a market for notebook computers, cell phones, and other portable devices from the iPod to the BlackBerry.

The benefit for consumers could be revolutionary: hybrid or pure electric cars with great efficiency, acceleration and range—at the same price or cheaper than today's conventional cars.
