First public lighting machine that runs on sun and wind electricity

This gadget, advanced after four years of studies, is designed for inter-city roads, motorways, city parks and different public areas. it is unique in the world and reduces the price with the aid of 20% compared with conventional public lighting fixtures 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). The builders' purpose is to make the lights system even greater environmentally green, so paintings is being accomplished on a 2nd prototype generator that runs at a decrease pace (10 to 60 rpm) and has a decrease output (one hundred W). An digital manipulate system manages the flow of strength among the sun panel, the wind turbine, the battery and the mild.

"It takes very little wind to supply electricity. The generator that has been advanced can start running at a wind velocity of most effective 1.7 metres in keeping with 2nd (m/s), whereas present day wind mills need extra than 2.five m/s," says Ramon Bargalló. "This low intensity can provide six nights of power without wind or solar," he provides.

to date, Eolgreen has signed agreements with the port of Huelva and the municipal government of Sant Boi de Llobregat, Girona and numerous towns in Andalusia. in the direction of 2015, the organization plans to supply seven-hundred of those avenue lights.
