Bio Lights is a light pole concept that let ‘ s the participants see how energy can be produced. It is an educational process that gives the user the satisfaction of being part of a green project. The poles function using algae and a water mill. Our aim is to show how wasted energy around us can be harvested in a clean way and thereby raise awareness about alternative ways of producing electricity within the city.

The poles‘ main power source is a hidden water mill. When people cycle or drive over a small “speed bump” placed on the street they displace a small quantity of water from the reservoir situated at the bottom of the pole, which then drives the water mill and produces electricity. The energy produced by the rotating wheel is stored in a battery, which later is used for illuminating the street of Mejlgade, which is a small part of a designated ”super—bike lane” — a 50 million kr project executed by the municipality and Aarhus Cykelby and supported by the state. Algae as energy source Bio Lights Light poles are made of a completely transparent material that allows people to see the algae inside. Incorporating algae into the lamp provides a secondary power source. During the day the algae produce energy from sunlight and C02 that can be stored in a second battery and used in case the primary energy source has not produced enough power that day. Furthermore, the addition of algae helps the environment as they feed off C02 and release 02 , which means that the poles also effectively fight pollution.

Bio Lights® designed for disassembly

Design for Disassembly (DfD) means that products are designed such that they can be reused and the materials they are made of also can be recycled. This is achieved by developing business models that encompass the maintenance, reparation and updating of products as well as, when the product has reached the end of its life, ensuring that the product can be disassem bled. As many components and materials as possible should be able to be reduced to clean, pure constituent parts that can be recycled — (so that waste is designed out).
