The name Blight may bring to mind images of biblical famines and pestilence, but it’s actually a sleek green gadget for your house. This new Blight is a solar blind that absorbs daylight during the day and sends it back at night. The designers say that Venetian blinds have an advantage because they have a large surface exposed to the sunlight in one small object. taking the daylight during the day and giving it back at night to power lamps, devices, and the whole infrastructure of your house. Blight uses flexible solar cells and electroluminescent foil to retrofit existing Venetian blinds. The blades can revolve, catching the maximum rays at different parts of the day.

Likelihood of being built: 8/10.

With some modifications, the Blight could be really useful and cool. I don’t know about the rest of you, but my Venetian blinds get so dusty that light wouldn’t be efficiently absorbed from their exterior. Could these guys self-dust? Also, the solar panels and foil are so expensive right now that the investment wouldn’t make sense. However, with the global silicon shortage over, prices are set to come down.
