Today's ecological problems are becoming more and more important, we must think of alternative energy sources. This lamp by Ikea SOLVINDEN related to this issue. Its name translates from Swedish as "Sun Wind", because they are two things that power. This is the LED lights are charged by the combination of lamp shade, which rotates in the wind, and sunlight hitting the solar panel on top. The solar panel also contains a sensor that seems to switch lights on when it's dark outside. Recharging time of 9-12 hours in sunlight, but more than 12 hours on a cloudy day. This is a cool solution for only $ 30 - no power cord and you can move it outside.
