In the modern world, fossil fuels are finite, not to mention CO2 emissions from their consumption that damage our atmosphere and raise global temperatures. Moreover, as day turns to night, our energy consumption often increases rather than reduces, and light pollution adds further issues to this problem. Light pollution does not just obscure the night sky for stargazers; the fact that there are lights everywhere in cities and towns plays havoc with nature too. Animals, especially birds, have their body clocks thrown out of kilter, having no idea if they see streetlights or dawn. However, TPA Instytut Badan Techniczynch, are rolling out bicycle paths in the town of Lidzbark Warminski in Poland.
Using “luminophores,” - lights charged by solar power from the sun during the day - they come to life at night and glow for up to 10 hours. Not only do they illuminate entire paths, but no electricity is needed to power them. Plus, lighting at night and dimming by day promotes the circadian rhythms of nature's creatures. The phosphors used to illuminate the paths come in a variety of colors and will be rolled out through Europe if successful in Poland.
