Solar Energy curtain adds charm to house

Swedish-based Interactive Studios took advantage of what nobody noticed before and came up with a solar-energy curtain. This modern window dressing builds up a charge over the course of the day, and uses up this charge to light up the night via its embedded materials. The curtain consists of cotton, solar-collecting and light-emitting materials. Draw the shade to collect light during the day and relax in its glowing ambience when dusk falls.
