WWII Bomb Shelter Becomes Hi-Tech Salad Farm Deep Under London
J Thoendell stashed this in Food
Thirty-three meters under the streets of central London is an old World War II bomb shelter that’s been transformed into a hi-tech underground farm.
The long tunnels beneath Clapham are being filled with stacked layers of hydroponic beds - forming "vertical farms" - for growing salads and herbs that can be delivered to tables in the city within four hours of harvesting.
The growing system uses energy-efficient LEDs instead of sun, no pesticides, needs 70 percent less water than growing plants in open fields, and less energy than a greenhouse.
“The whole system runs automatically, with an environmental computer controlling the lighting, temperature, nutrients and air flow,” explains Steven Dring, co-founder of the company behind the operation, Zero Carbon Food.
