Seeking to make bike paths safer and more accessible in the evening and night hours, urban planners in Lidzbark Warminski, Poland just unveiled a new glow-in-the-dark bike lane. The path is made from small crystal-like particles of phosphor called ‘luminophores’ that charge during sunlight hours and can glow for up to 10 hours. The lane was built by TPA Instytut Badan Technicznych Sp. z o.o who were partially inspired by Studio Roosegaarde’s stunning solar-powered bike path in the Netherlands mentioned here in 2014. Unlike the Netherland’s concept which uses solar-powered LEDs, this new path in Poland requires no external power source. The design is currently being tested to see how it withstands regular wear and tear. You can read more over on Inhabitat .
