Japanese Farmer Builds High-Tech Indoor Veggie Factory

 

 

Humans have spent the last 10,000 years mastering agriculture. But a freak summer storm or bad drought can still mar many a well-planted harvest. Not anymore, says Japanese plant physiologist Shigeharu Shimamura, who has moved industrial-scale farming under the roof.
 
Working in Miyagi Prefecture in eastern Japan, which was badly hit by powerful earthquake and tsunamis in 2011, Shimamura turned a former Sony Corporation semiconductor factory into the world’s largest indoor farm illuminated by LEDs. The special LED fixtures were developed by GE and emit light at wavelengths optimal for plant growth. 
 
The farm is nearly half the size of a football field (25,000 square feet). It opened on July and it is already producing 10,000 heads of lettuce per day. “I knew how to grow good vegetables biologically and I wanted to integrate that knowledge with hardware to make things happen,” Shimamura says.
 
The concept took off in 2011, when GE approached Shimamura with an idea for using advanced LED lights to illuminate the farm. The LEDs last longer and consume 40 percent less power than fluorescent lights. The companies started testing the technology in March 2012 and came up with the final design a year later.
