Battery in a drum rolled out
GERMANY - A lithium-titanium battery pack in a rolling white drum can supply 300 watts of power from a 1 kilowatt-hour reserve.
That's enough to power a computer workstation for 2 or 3 days, or to recharge a cell phone almost indefinitely, according to Younicos, the German company that invented the pack.
The mobile energy storage unit, called Yill, is a couple of feet in diameter, about the size of a small bass drum, with a handle and wheels. It recharges in about four hours in a 220-volt electric outlet.
