At 8 bucks a pop, it's definitely a tad on the costly side... However, I certainly do think it's a pretty ecoCool idea!




At 8 bucks a pop, it's definitely a tad on the costly side... However, I certainly do think it's a pretty ecoCool idea!

A schoolboy from Nepal has come up with a recession-busting new solar panel which replaces the silicon component with human hair. Milan Karki, an 18-year-old student from the region of Khotang, devised the idea after discovering that hair pigment Melanin acts as an energy converter.
Each panel, which is around 15 inches square, produces 9 Volts (18 Watts) of energy, and costs $38 to make. This, it has to be said, is mainly due to the price of the raw materials: half a kilo of human hair costs around 25¢ in Nepal. Karki is hoping to commercialize his invention, which can charge a cellphone or power batteries to provide an evening's worth of light, and eventually mass produce it.
"First I wanted to provide electricity for my home, then my village," says Karki, who was inspired by British physicist Stephen Hawking. "Now I am thinking for the whole world. We have begun the long walk to save the planet." Catch a shot of the teenager's invention below.

I was inspired by the flowers I'd added to my pulling the February Giveaway Winner out of my bright pink beret, that I drew the green light bulb above. Whatcha think? Okay, perhaps I should leave the art to Designerjots ;)
"The Smarthome Screw-in Motion Sensing Light Adapter, as the name applies, screws into a typical bulb socket — no screwdrivers required. Turn on the light switch and the bulb will turn on only when it detects motion, then shuts off automatically when there's no movement within a 16-foot range. The length of time it stays on is adjustable from 5 to 100 seconds. It retails for $25, but who knows how much you'll save in energy costs?" Available at Amazon.
Also on dvice, I came across another cool light-related feature, this time regarding lighting whole street blocks... On call! That's right "on call." Cities are no exception to the need to save on green (cash variety) and so it's no surprise that "towns all over the work have started turning off their street lighting to save money."
"Not only does this technology [by Green Peak] enable better remote controls - they'll work through walls up to nearly a hundred feet away - but could help eliminate the 8 billion dead remote control AA and AAA batteries that are tossed into the garbage each year."If you hear of an exciting eco-innovation, please do share. Thanks for stopping by :)
