Regular window blinds already help people to save electricity – by keeping incoming sunlight from heating a room up, they reduce the need to run an air conditioner. SolarGaps, however, take things a step further. Each slat is equipped with an array of monocrystalline solar panels, which generate electricity via the very sunlight that they’re blocking. Additionally, the blinds use a light sensor to track the sun, automatically changing the angle of the slats in order to best absorb its rays.
Invented by entrepreneur Yevgen Erik, SolarGaps 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 up to 50 watt-hours when mounted inside.
The energy that they produce can be fed into the municipal grid and sold to the local utility company, stored in a battery for later use, or it can be used as it’s being generated, for purposes such as charging electronic devices.
