Although his vision for indoor food cultivation dates back many decades, a Japanese botanist, Shigeharu Shimamura, used the earthquake and tsunami disaster of 2011 as a catalyst to start a stunning new factory farm that produces 10,000 heads of high quality leafy lettuce per day with staggering efficiency.
The nuclear disaster at the Fukushima plant occurred in an agricultural region of the small country and produced rampant food shortages. The Japanese government wanted to provide subsidies to spur development in Miyagi -- a perfect opportunity to produce the farm of the future.
Taking over a giant semiconductor factory vacated after the earthquake, Shimamura's company, Mirai (which means 'future' in Japanese) drew up design plans for the indoor vertical farm and contracted General Electric to co-develop a special LED lighting system. A third company was hired to reconstruct the facility using the structure's special characteristics, such as clean-room facilities, thermal insulation and high ceilings, and to engineer a rack system for cultivation.
The facility run by Mirai uses towering rows of thin soil trays and exact measurements for temperature, humidity, light and darkness, to create 100 times more vegetables per square foot than traditional agriculture methods. The bacteria-free, pesticide-free environment cuts food waste by 30-40 percent compared to lettuce grown outdoors.
