Virtual Flaneurism

Check out this article about the surprising survival of Japan's wind farms post-tsunami, making the kaput nuclear reactors that are hate-vomiting out radiation look positively archaic in design. An excerpt:

"Even the country's totally bad ass Kamisu offshore wind farm, with its giant 2 MW turbines with blades big as the wings on a jumbo jet, and only 186 miles from the epicenter of the largest quake ever recorded in Japan, survived without a hiccup thanks to its "battle proof design." As a result, the nation's electric companies have asked all of its wind farms to increase power production to maximum, in order to make up for the shortfalls brought about by the failure of certain other aging, non-resilient 20th-century technologies."

I really want to know what "battle proof design" means. I'm imagining some sort of wind-powered Koopa Fortress, and I very much so want that to be accurate.
