TechCrunch reports on a new bicycle path built in the Polish city of Pruszków. The surface of the path is phosphorescent: after a sunny day, it will glow through the nightime.

According to BBC News, there was a similar project in the Netherlands in 2014: phosphorescent paint was applied to 500 m (547 yards) of a highway. The hope was that the markings could replace electric lights.

    This is similar to the glow-in-the-dark stars you would stick on your bedroom ceiling. Not as bright as source lighting every couple hundred feet. And, additionally the sidewalk will taper in intensity with time, so by the wee hours of the morning there is no light coming off them.

    However I think neither of these are replacing major sources of light pollution, such as road way lighting or parking lot lighting. Those security lights are bright enough to read by, and really drive the light pollution of a city.
