Once again, the government is worried about hackers attacking America's power grid. This time, homeland security made a video
of what happens if you hack the controls of a turbine using a programming flaw, making it overload and break apart. "It's so graphic. Talking about bits and bytes doesn't have the same impact as seeing something catch fire." Dick Cheney is also said to have seen the video. "Is this something we should be concerned about? Yes," said a Homeland Security official.
