It was also a bright week for renewable energy with a revolutionary spherical solar cell capable of capturing light from all directions, and Austria Solar sending out a "sun-powered" annual report that only appears when exposed to sunlight. Meanwhile, we said goodbye to the polluting energy technology of the past as Midwest utilities shuttered 10 fossil fuel-powered plants and the world's oldest nuclear reactor closed up shop in the UK. Brilliant designers also chased away dark winter days with a sunflower-shaped heliostat that can flood any house with natural light and a cheap, photovoltaic Little Sun lamp for the developing world.
Green tech also wired the world in exciting new ways as the Smithonian Institute announced plans to replicate and share its collection with the world using 3D printing tech and a 14-year-old boy invented an incredible LEGO printer. We also watched HP launch an all-in-one workstation that pops open for easy DIY upgrades and repairs, while Huawei unveiled a soaring Pegasus sculpture made from 3,500 smartphones. Last but not least we brought you a look at Google's new Terminator-style augmented vision goggles, and we shared a fun tutorial on geocaching with your children.
