The online green tech community has been abuzz with a new outdoor LED light from the University of Seville in Spain. This unit comes with smart controls and can be used both on and off the grid. While scientists and designers have been collaborating on solar-powered street lights for a few years, this prototype partners it with wind power.
Solar panels store energy in a battery (admittedly not the most efficient power source, making it more suited to low-energy applications like solid state lighting). On an overcast day, the battery cell does not get charged, so that is where the backup wind power comes into effect. Wind is a guaranteed phenomenon on roads, as it is generated by human activity – driving. Which brings one to wonder why the solar panels are necessary in the first place. Perhaps it minimizes wear and tear on a single power source? Can anyone shed some light on this? (ducks)
This renewable-powered piece of technology is called the Holonic Streetlamp, but because of the LED light bulbs inside we like to think of it as the Holonyak Streetlamp.
thanks to you i have learned something new today, thanks a lot.
