People who live in private homes have the option to install solar panels and residential wind turbines on their roofs, but what about those of us who live in apartment buildings? Well, the Greenerator is a compact solar and wind energy collector that can be installed right on an apartment balcony. It looks a lot like a high-tech wind chime and is equipped with a vertical axis wind turbine and flexible solar panels. According to the designer, Jonathan Globerson, each unit can reduce your electricity bills by 6 percent and can save 2000 pounds of CO2 emissions annually.
