Poland is kicking the concept of a traditional bike trail to the curb.
On Sept. 23, the rural town of Lidzbark Warminski opened a short biking path that glows blue in the dark. Charging by day via the sun, the special section of trail is a new addition to a larger recreation path that leads up to Wielochowskie Lake.
European engineering company TPA sp. z o.o designed the technology that lights this segment of the bike path. The asphalt contains synthetic particles called “luminophores,” which at night emit power captured from sunlight, creating the electric blue hue. TPA says the glow lasts up to 10 hours, according to Polish newspaper Gazeta Olsztyńska.
