Spain has developed a new street light, powered by solar and wind Bashny.Net

At present, many cities to reduce energy consumption, often do not leave outdoor lights on all night. Of course, the idea of developing street lights that feed on the power generated by integrated solar panels, received the support of many research teams around the world. But a group of scientists and engineers from Spain went even further and developed a prototype of a new Autonomous street lamp that runs on solar and wind energy.

This project is being developed in cooperation between the Polytechnic University of Catalonia and the Spanish start-up Eolgreen. The existing prototype 10-meter height are equipped with an array of LEDs from Philips, photovoltaic panels, wind turbine, battery pack and electronic control system that monitors and manages energy flow between these components.

Wind turbine composite blades starts generating electricity at a minimum wind speed of 1.7 meters per second, performing from 10 to 200 revolutions per minute and producing a maximum power of 400 watts. Plan to install a wind turbine of the second generation will be included at 10 to 60 rpm and will be capable of producing 100 watts.

Commercial version of the street lamp will be equipped with two 100-watt polycrystalline solar panels, led brightness 3500 or 4000 lumens (depending on model), and lithium-iron-phosphate battery that can store sufficient electricity to operate the LEDs within 3.5 days. The developers have also provided an extra battery with a larger capacity that will ensure the efficiency of the street lamp to 6.5 days.

Street lights can work completely offline, but it is also possible to combine them into groups (up to 99 units) to send to the Central unit reports of health status every 30 minutes (in the UHF band). This will allow administrators to detect any technical failures of the devices and eliminate them quickly.

To date, the company Eolgreen signed an agreement with several Spanish municipalities about installing new street lights, and this year plans to produce 700 units. It should be noted that in the present University of Seville is also working on a project of solar-wind lamps, and new York-based company Urban Green Energy is already producing a similar device in the United States.
