Dutch designer Van Aubel designed the lamp as part of an ongoing project to normalize solar technology by bringing it inside homes, and that's why he hung it in front of windows so it can generate its own energy.
Called Sunne, the light is equipped with photovoltaic cells and an integrated battery, allowing it to harvest and store enough energy throughout the day to light up a room at night.
Without the need for a plug or external electricals, the light is reduced to the shape of a simple oblong suspended from a steel wire at either end.
The side facing the window incorporates SunPower Solar Cells, which Van Aubel developed in collaboration with The Energy Research Centre of the Netherlands.
