French company Windela has created a street lighting system that works without any connection to the grid. The lamp called Windelux is is actually three products in one. The device is composed from small vertical wind turbine and a solar PV panel.
The actual lamp is has 84 LEDs and automatically switches on when a photosensitive cell detects that it’s dark. A built-in control system stops the wind generator if the wind speed is too high (20meters per second).
Inside the pole is the battery which is charged by the Wind generator and also by the solar pannels. It’s a rechargable LiFePo battery and supplies four nights worth of light before needing to be recharged.
Currently, there are units, that have only been installed in France and Algeria, but I think that with all this great features and possible saving features without needing having grid those kind of devices will became rapidly a standard.
See a small video presenting the device.
