A California startup has designed window blinds with solar panels that can block out sunlight while harvesting the solar energy. SolarGaps, based in Los Angeles, has designed each slat in the blinds with monocrystalline solar panels in order to harvest solar energy. The blinds can track the sun path and automatically change the angle of the slats in order to optimize the its absorption of sunlight. The solar blinds are reportedly able to generate up to 100 watt-hours of energy for every square meter when mounted on the outside of a window, or half of that amount when mounted inside. Users can manually control the blinds and monitor energy-saving information via an app. SolarGaps hopes to raise $50,000 from Kickstarter in order to mass-produce the solar window blinds.
