#10: Photoluminescent Paint, France
Driving or walking down an unlit road at night can be pretty terrifying. Your surrounding environment can be so dark that anything can jump out at you without warning. To prevent this, developers in France thought up the genius idea of using photoluminescent paint along their pedestrian walkways.
The paint absorbs sunlight during the day, allowing the paint to glow in the dark for 10 to 12 hours. This is a wonderful way to illuminate wayfinding without using electricity. It doesn’t necessarily add more lighting to a pathway, but it makes the symbols and lanes pretty clear. This can easily be used on roads for cars, too.
