Designers Kyuho Song & Boa Oh have developed the brilliant Window Socket, a portable device intended to enable you to use electricity freely and conveniently in a space restricted in the use of electricity, such as a plane, a car, and outdoors. The Window Socket attaches easily to any window and is charged with solar energy that is then converted into electric energy through a converter. The clever product is currently in concept stage, with the designers looking to improve storage capacity and efficiency.
