Gravity Squeezes 40 percent More Power From These Solar Panels

At first glance, Eden Full may seem like a typical Princeton undergrad, but she’s far from typical. The 21-year-old is a Thiel Fellow and inventor of The SunSaluter, a solar panel that pivots to face the sun without requiring a motor. Full didn’t set out to radicalize the way the developing world sources power — she was a self-proclaimed “solar enthusiast” by the age of 10. But her ingenuity and a tip from someone at an international science fair led her to optimize solar energy, so a solar panel produces up to 40% more electricity. And all it takes is gravity and some soda bottles.
