The new development is currently being tested in Cambridge. The StarPath material has been applied to local pedestrian paths. During daylight hours, the coating absorbs ultraviolet rays, and at night it gradually releases the accumulated energy. An important feature is that the composition works regardless of how well the area is lit at any given moment.
Another significant advantage is StarPath's ability to change the glow intensity depending on the lighting level. As soon as the sun rises, the road surface begins to smoothly lose its luminosity.
This effect is achieved thanks to complex phosphorescent elements in the material's structure. If the tests are successful, the technology could be used not only for highways but also for illuminating paths where installing conventional streetlights would be too costly.
