The biggest chemical battery in the United States is located near Interstate 90 in the small town of Luverne, Minn. The 80 ton device -- the size of two tractor-trailers stacked on top of each other -- stores as much energy as about 3 million rechargeable AA batteries and can power about 3,000 houses for more than an hour when discharging at its maximum rate.
