Breathing new life into the ancient art of ‘stained-glass’, a window that harvests solar energy and can charge your mobile phone sounds like more than just a design feature.
The aptly-named Current Window by Dutch designer Marjan van Aubel is made of coloured solar cells and can harvest up to 25 watts per day, depending on the quality of light and the season. A back-up battery hidden in the windowsill stores left-over energy to provide power on overcast days.
