UK company testing glow-in-the-dark street, sidewalk coating
- A company in the UK, Pro-Teq, is testing a spray-on coating for streets and sidewalks that glows at night, using energy absorbed as ultraviolet light during daylight hours.
- The surface might offer a way to greatly reduce the need for street lighting, making it an energy-saving technology.
- Pro-Teq says the coating, called Starpath, has particles that can vary the intensity of the emitted light to mesh with available light in the area.
The company says the coating goes on quickly, saying it did a 1,600-square-foot test area in a park in Cambridge in a half-hour. Starpath comes in 11 colors and is non-reflective, Pro-Teq says, and can be rejuvenated with a new application when one begins to dim. How long that coating will last is not being reported yet, but Starpath does seem like a product that could change the look and feel of subdivisions and enhance safety on rural roads that are unlighted now.
