Inhabitat's Week in Green: Self-driving Uber cars, and more!

It was big week for solar power as well. For starters, scientists developed a breakthrough photovoltaic cell that set a new world record for efficiency. Portugal made headlines by running on 100-percent renewable energy for more than four days. The Mistbox is a new device that uses solar energy to cut down on summer cooling costs. And scientists discovered a new form of spiralized light that flies in the face of everything quantum physics says about photons.
