In the recent past, Scientists have developed the first autonomous industrialized public lighting system that works with solar and wind energy.
This system, developed after four years of research, is designed for inter-urban roads, motorways, urban parks and other public areas. It is unique in the world and reduces the cost by 20% compared with conventional public lighting systems.
· The prototype is 10 metres high and is fitted with a solar panel, a wind turbine and a battery.
· The turbine runs at a speed of 10 to 200 revolutions per minute (rpm) and has a maximum output of 400 watts (W).
· An electronic control system manages the flow of energy between the solar panel, the wind turbine, the battery and the light.
It takes very little wind to produce energy. The generator that has been developed can start working at a wind speed of only 1.7 metres per second (m/s), whereas current wind turbines need more than 2.5 m/s. This low intensity can provide six nights of electricity without wind or sun.
