That baggage is getting heavier. Although half of the world’s population already lives in cities, the U.N. estimates that the number will spill over the 50 percent mark and hit 5 billion by 2030.
It’s the afternoon rush hour just outside central London and the traffic is nose to tail. Drivers here have come to expect the sight of taillights as far as they can see. One section of road, a stretch of the A3 close to Heathrow Airport, has been named Britain’s most congested road and has holdups totaling 91 hours during the afternoon rush each year.
A warehouse full of lettuce might not be the first place you would expect to find the next Industrial Revolution. But follow the LED lights and you’ll discover a glimpse of the future of agriculture — industrial-scale, indoor farming.
Advances in LED technology are helping to create an environment where vegetables can be produced at scale, with higher yields and shorter grow cycles, no matter what climate.
More than a century after Thomas Edison got into the light bulb business, his bright idea is getting brainy.
Engineers at GE, the company Edison founded, have helped develop an affordable LED light bulb that can talk to its owners’ tablets and smartphones. The bulb, which starts at just under $15, contains a chip that can wirelessly connect to the Internet and communicate with users via a mobile app called Wink.
Cleveland’s historic Playhouse Square turned on the world’s largest permanent outdoor chandelier on Friday. The 20-foot tall stainless steel light piece shimmers with 4,200 crystal pendants and LEDs fixtures drawing just 1,700 watts (the equivalent of 17 standard 100-watt light bulbs.)
The GE Chandelier, as it is called, was designed by Montreal’s Lumid and uses LEDs and light modules built by GE.
Fifty years ago, physicist Nick Holonyak was tinkering with lasers in his GE lab when he discovered the world’s first light-emitting diode. “We knew what happened and that we had a powerful way of converting electric current directly into light,” Holonyak says. “We had the ultimate lamp.” His team called it “the Magic One.”
