Petawatt laser

Well, according to Wired, it’s the power output of the world’s most powerful laser. Built at the University of Texas at Austin is pretty much the kind of laser an evil genius would put on the moon in order to hold the world hostage.

How much is a petawatt? Well, in zeros it is 1,000,000,000,000,000 watts of power. I wonder if in a couple decades we’ll have petabyte hard drives and petabyte CPUs?

*Let it be known it was a struggle to decide whether to make a Back to the Future, Austin Powers or a Real Genius reference.
