Light the Cities of the Future

A previously unlit cycle path in the Netherlands has recently drawn our attention. It has been resurfaced with a material that consists of thousands of shining stones in order to create a well-lit route. The Van Gogh Path, so called after the artist who lived in the town of Nuenen in 1883, combines the traditional with the contemporary in a gesture that acknowledge ledges Van Gingh’ masterpiece The Starry Night, but also shows the way ahead for city lighting. The Van Gogh Path is not a single case; it is not difficult to foresee a time when natural materials could help light the cities of the future.

Why should we care about city lighting? What’s wrong with current electrical city lighting anyway? Well, the problem that it causes is two-fold. First, of course, electrical lighting in most cities comes from non-renewable resources. According to the International Energy Agency, almost 20% of global electricity is consumed for lighting, which is responsible for high levels of carbon emissions. But there’s also the belief that electrical light itself is a form of pollution by destroying our view of the night sky.

From the above reasons, then, it seems wise to investigate other approaches. The city of Glasgow is attempting to use intelligent street lighting to monitor how citizens interact with the urban landscape and minimize electrical consumption and thus emissions. This “Smart City approach” is seen by many as the way of the future, but some designers aren’t convinced. They are pioneering the altogether more original approach of using materials from the natural world in order to replace electrical light entirely. They believe that this new “technology” can one day completely replace microchips and digital systems as we find better ways of making use of the light-producing mechanisms (制) that already exist in the natural world.
