Star Path

The UK company ProTeq Surfacing has come up with a novel method for lighting park pathways and other public surfaces. Their new Starpath technology can be sprayed onto concrete, wood and other solid surfaces to make them light up at night. The company envisions Starpath as a way for municipalities to lower their electrical bills by allowing them to turn off street lights. Starpath works by absorbing and storing energy from ambient daytime light, energy which is then released in the form of a bluishglowing light. It's basically the same thing that happens when you take a glowinthedark keychain and hold it up to a lightbulb; turn the lights off and you'll find you now have a brightlyglowing keychain. That's because shining a light on a glowinthedark keychain excites its phosphors, photoluminescent chemicals like zinc sulphide or strontium aluminate. The incoming photons are stored in the keychain, and when they're released, the object glows. Starpath is made up of three layers: a polyurethane base, a layer of lightabsorbing chemicals (like those described above) and a waterproof coat to finish it off. The material is also antislip, and of course Starpath uses no electricity. "This product adjusts to the natural light, so if it is pitch black outside the luminous natural earth enhances, and if the sky is lighter, it won't release as much luminosity ‐‐ it adjusts accordingly, its almost like it has a mind of its own," said ProTeq owner Hamish Scott in a press release. Scott called it "pure nature doing its work." Starpath is currently being trialled in Christ's Pieces, a park in Cambridge, England. As the Independent notes, Starpath isn't bright enough to replace street lights entirely, but the system is suitable for low foot traffic areas where municipalities may try to cut electrical costs by turning off lights altogether. According to the Smithsonian, Starpath costs $10.50 per square foot. Watch the video below to see how Starpath is installed, and what the finished product looks like. It's all pretty cool, but is it as cool as this?

The UK company Pro‐Teq Surfacing has come up with a novel method for lighting park pathways and other public surfaces. Their new Starpath technology can be sprayed onto concrete, wood and other solid surfaces to make them light up at night. The company envisions Starpath as a way for municipalities to lower their electrical bills by allowing them to turn off street lights. 

Starpath works by absorbing and storing energy from ambient daytime light, energy which is then released in the form of a bluish‐glowing light. It's basically the same thing that happens when you take a glow‐in‐the‐dark keychain and hold it up to a lightbulb; turn the lights off and you'll find you now have a brightly‐glowing keychain. That's because shining a light on a glow‐in‐the‐dark keychain excites its phosphors, photoluminescent chemicals like zinc sulphide or strontium aluminate. The incoming photons are stored in the keychain, and when they're released, the object glows. 

Starpath is made up of three layers: a polyurethane base, a layer of light‐absorbing chemicals (like those described above) and a waterproof coat to finish it off. The material is also anti‐slip, and of course Starpath uses no electricity. 

"This product adjusts to the natural light, so if it is pitch black outside the luminous natural earth enhances, and if the sky is lighter, it won't release as much luminosity ‐‐ it adjusts accordingly, its almost like it has a mind of its own," said Pro‐Teq owner Hamish Scott in a press release. Scott called it "pure nature doing its work." 

Starpath is currently being trialled in Christ's Pieces, a park in Cambridge, England. As the Independent notes, Starpath isn't bright enough to replace street lights entirely, but the system is suitable for low foot traffic areas where municipalities may try to cut electrical costs by turning off lights altogether. According to the Smithsonian, Starpath costs $10.50 per square foot.  

Watch the video below to see how Starpath is installed, and what the finished product looks like. It's all pretty cool, but is it as cool as this?

UK company Pro‐Teq has developed a new water‐resistant, spray‐on coating that absorbs UV light during the day and releases it at night, adapting to the lighting conditions in its surroundings. The technology is being given a test run at the Christ's Pieces park in Cambridge, and could prove a cost effective alternative to conventional street lighting. 

We're used to seeing solar‐harvesting technology being installed primarily on rooftops, but other sufficiently irradiated surfaces, including sidewalks, are also being explored for their energy harvesting potential. 

Starpath doesn't produce electricity, but it does offer a possible alternative to street lighting, with very low installation and maintenance costs, as it can be just sprayed onto an existing surface and then further coated to make it waterproof. According to the company, the coating absorbs and stores UV light during the day and releases it at night, when its particles are able to adjust to the available natural light, and glow with the appropriate level of intensity. 

The coating is currently being trialled in Christ’s Pieces, a park in the center of Cambridge, UK, where it has been sprayed on a total area of 150 sq m (1,600 sq ft). Pro‐Teq says the coating took only 30 minutes to apply, with the surface being ready for use after only four hours. 

"Our surface works best over tarmac or concrete, predominantly tarmac, which is the main bulk of the UK path network," explains Pro‐Teq sales director Neil Blackmore. "When it's coming to the end of its useful life, we can rejuvenate it with our system, creating not only a practical, but a decorative finish." 

Starpath has anti‐slip properties, and can help users avoid collisions at night, without resorting to artificially‐painted lines to divide the path. The coating is also non‐reflective, and the company website lists a choice of 11 different colors. On the flipside, problems might be encountered during the winter months, with less light available during the day and the possibility of snow blocking out light from the path. 

The video below details how the resurfacing technology works and explains how quickly the coating can be laid out onto a path.
