While LED technology has, in some ways, become the latest poster child for the future of energy-efficient lighting, it hasn’t discouraged entrepreneurs from tinkering with a few intriguing alternatives that happen to not require any electricity at all.
Earlier this week, I wrote about an algae-powered street lamp, currently being developed by a French biochemist, that absorbs carbon dioxide along with photosynthesized sunlight and, in return, produces oxygen and bio-illumination for streets and parking lots. Well, in the United Kingdom, a businessman named Hamish Scott hit upon a similarly bright idea in creating Starpath, a special luminescent coating for common ground surfaces that collects and stores energy from ambient light during daylight hours and releases a blueish, galactic glow when it gets dark. The multi-layered organic material, which may cut electricity bills, has proven promising enough that city officials in Cambridge have opted to try the technology at Christ’s Pieces park where 1,600 square feet of a pathway were renovated.
Decorate your lawn with these Glow in the Dark pebbles! This comes with 100 in a pack, enough to make your lawn really cool! These pebbles absorb sunlight during the day and light up at night. Perfect for lining your walkway or highlighting flowerbeds. Stays lit for about 3 hours after absorbing full sunlight.
Be creative! Design your own pattern and change as you wish.
What’s remarkable about Starpath is that while the material, a high-grade version of what’s found in glow-in-the-dark toys, can generate reliable illumination for about 16 continuous hours, it also exhibits “smart” sensing qualities that allow it to adjust to varying light conditions, brightening up just enough during the early evenings and going into full effect when the sun is down. Though Scott says that Starpath loses luminosity over time, most observers will still be able see people walking toward them and even make out what the person is wearing. It’s also environmentally friendly and 100 percent recyclable.
“It is quite a cool thing. Until you have seen it, you can’t really comprehend it,” Scott told the Fairfax NZ News in a seperate interview. Naturally, one might wonder if a park with Starpath, as opposed to lamp posts, is safely lit. But, Scott adds, “When you are walking down a pathway you know what is around you. From 80 metres away you could tell if someone had a tie on or was male or female.”
