Bomb shelters as underground farms

Underground the city of London are eight massive bomb shelters like the one pictured above that have been empty or used as document storage for more than 50 years. Now, one of them is being transformed into a subterranean farm. The farming group, called Zero Carbon Food, based their system on hydroponics and LED light powered by wind-generated electricity.
"When I first met these guys I thought they were absolutely crazy, but when I visited the tunnels and sampled the delicious produce they are already growing down there I was blown away," says two Michelin star chef Michel Roux Jr.
