Power in back

Four-year-old Boston Power has applied for $100 million in federal grants from the Department of Energy to build a lithium ion battery factory in Auburn, a town in central Massachusetts near Boston Power's Westborough headquarters.

Boston Power held a press conference on Monday at the proposed site, now a retail distribution warehouse, and showed off a converted Ford Escape that runs on Boston Power's batteries, which were originally developed for laptop PCs.
