It may appear a little awkward - although in an extremely futuristic way - to have a power outlet coming directly out of a window. While it doesn't make much sense aesthetically it makes a lot of sense ecologically.

The solar energy powered socket designed by Kyuho Song & Boa Oh is a great example of an efficient and environmentally friendly option for convenient energy consumption. Easily attachable to the window glass, the plastic socket with integrated solar panels charges up to 1000mAh providing power for about 10 hours after complete charge. Once fully charged you can easily throw the tennis-ball-sized socket in your bag and have access to electricity in places totally 'unplugged' from the grid.
