There has long been a discussion about the kinetic nature of cyber warfare. Today CNN brings us video of a largish hole in the power grid. Kinetic effect without the kinetic cost. I wonder what the cost of a laptop and Internet connection is in relationship to a 500lb bomb (or dozens).

Sources: Staged cyber attack reveals vulnerability in power grid

WASHINGTON (CNN) -- Researchers who launched an experimental cyber attack caused a generator to self-destruct, alarming the federal government and electrical industry about what might happen if such an attack were carried out on a larger scale, CNN has learned.

Department of Homeland Security video shows a generator spewing smoke after a staged experiment.

Sources familiar with the experiment said the same attack scenario could be used against huge generators that produce the country's electric power.

Some experts fear bigger, coordinated attacks could cause widespread damage to electric infrastructure that could take months to fix.

CNN has honored a request from the Department of Homeland Security not to divulge certain details about the experiment, dubbed "Aurora," and conducted in March at the Department of Energy's Idaho lab

In a previously classified video of the test CNN obtained, the generator shakes and smokes, and then stops.
