Poland launched a brand new sun-powered bike lane that glows bright blue all night long. The bicycle lane is becoming a tourist attraction because of the creepy ghostly blue that it emits in dark. The path near Lidzbark Warminski in the Mazury region is illuminated by blue luminophores, a synthetic material that emits light after it’s charged by sunlight. While the Starry Night bike path in Netherlands provided inspiration, the technology utilized in the Polish bike lane is quite different. The Dutch path lights up via solar-powered LEDs, whereas the Polish path requires no additional power supply.
