A few years ago the Dutch government decided to implement the project Icoon Afsluitdijk, the essence of which is to make all national roads energy-neutral. Among other items it includes the use of luminous algae is lighting and production of renewable energy. The first object with environmentally friendly lighting has become afsluitdijk, whose length is almost 30 kilometers and the width is 90 meters.
The dam was built in the early twentieth century, blocking the Bay Seilersee in the North sea, and combining with it the North Holland and Friesland. Now it is a major highway and daily passes to 20 thousand cars, so the engineers at Studio Roosegaarde have decided to cover in the first place, covering the dam reflective paint and light-scattering prisms. Now the bridge is lit from the headlights of passing cars and does not need electricity.
The project is going to implement by 2030, along the way experimenting with different natural lighting, for example fluorescent algae.
