The first combined lamp-post and wind turbine will
be installed on the bridge at Castillon-la-Bataille,
in Gironde, France, by the end of the month.
According to its designer, Michel Justo - "this
is a genuinely new product in the French market."
Q standard metal post is fitted with a low-energy lightbulb
and hooked up to a 12-volt, 100-ampere battery, which
is continuously charged by a 300-watt wind turbine.

The idea was developed by Aquitaine Aérogénérateurs
in early 2006. It is original and cheaper than solar energy
- between €1,500 and €1,800 before tax.

The system can be retro-fitted to older lamp-posts,
says Justo.
"All you need to do is to attach the turbine to
the top of the pole and change a few parts in the lamp."
The device can also be networked - by keeping the electric
cabling and installing a 1,000 or 2,000 W turbine upstream
from 20 or 30 street lights. Developed for public lighting,
it is also suitable for private use.
