This beautiful Solar Paper Lantern is made out of 36 miniature solar panels. Each panels is connected to an electroluminescent diode, meaning the entire thing is powered by the sun. It's not only lovely, but it's environmentally friendly, too. It can remain on for as long as it's near the sun.
The only problem with this is that when it's near the sun, you won't need the light source, so it's best to leave it in the sun all day to juice it up for shining its light at night. But it's a great twist on a classic design, one that I'd love to have to show off in my home.
