Berkeley laser fires pulses hundreds of times more powerful than all the world's electric plants combined

Imagine a device capable of delivering more power than all of the world s electric plants. But this is not a prop for the next James Bond movie. A new laser at Lawrence Berkeley National Laboratory was put through its paces July 20, delivering pulses with a petawatt of power once per second. A petawatt is 1015 watts, or 1,000,000,000,000,000 watts about 400 times as much as the combined instantaneous output of all the world s electric plants.
