There is a building in Hamburg, Germany, and developed entirely by algae. Inside the glass panels is a green liquid which can see small bubbles rising to the surface. This is the result of having a bio-reactor built into the facade, which heats the 15 floors in the building. The motor is a micro algae, and the principle is photosynthesis.
Therefore, the building itself is heated actually. The balcony is like an aquarium with all the algae growing there. Also, this is a “passive house”, ie maintaining a comfortable indoor temperature without heating, which also means saving money.
To prepare for winter, the building has underground shops of the heat produced during the summer, which can then be used several months later.
But it is not just heating. The project is also designed so that the dead algae can be collected and used to make a nutritional supplement that is rich in minerals.
