A bike path in the Netherlands helps bikers see where they’re going without using electricity. This is part of a project called SMART HIGHWAY designed by Daan Roosegaarde.
Based on the report from Scientific American, the bike path was built using phosphorescent tiles which gives it the starry effect at night. One researcher states that phosphorescent cement could one day be produced to light pathways and ultimately major roads.
The phosphorescent material in the cement absorbs radiation like ultraviolet. This means that during the day, the cement charges up and in the evening emits the stored radiation as visible light to help navigate people and vehicles. The glow is estimated to last up to 12 hours.
The applications for low cost lighting solutions is outstanding especially with energy demands projected to increase drastically over the coming years. And of course the aesthetic value can’t be overlooked. Alfred Bayle
