A Danish company developed a solar street light that feeds power back into the grid.
Scotia, the company that developed the SunMast is testing its new street lamps in the UK. Since street lights don't use a ton of power, each lamp collects more energy than it needs to keep the lights on. Rather than waste all of that energy, the SunMast street lamp feeds it back into the grid, which the company predicts will reduce emissions from the street lights by 120 percent!
The solar cells that cover each street light are designed to collect power even on cloudy days, which is especially important when you're talking about a climate like England's. Scotia is testing their lights in South Mimms in the UK, and the SunMast also lit up parts of Copenhagen during COP15.
The concept sort of reminds me of those poop powered park lamps in Cambridge, Massachussets. Both of these innovations are doing double duty by providing clean energy and a service at the same time.
Have you guys run across any cool, solar innovations? I'd love to hear about them in the comments!
