This is such a beautiful concept that we hope we do not have to wait until 2030 to see it in production. But if it takes that long, we're willing to wait. The paper has two layers: the outer surface functions as a PV cell, generating electricity, and the inner surface functions as a battery. The flaps move out to show how much energy the wallpaper has generated.
The idea is to create a beautiful expression of green values. The concept succeeds magnificently.
