A façade of glass panels is filled with water, microalgae, nutrients and CO2. Solar radiation generates oxygen and warm water. CO2 is broken down, good for climate protection :-)

Micro algae, water, nutrients and CO2 are placed in window-like glass panels on a house facade. Under sunlight, the algae grow and multiply and photosynthesis takes place. CO2 is converted into oxygen. This creates heat.

The heat is used for the operation of the heating and for the production of warm water. In Hamburg, Germany, there is already the first house with such a facade which supplies its 30 residents with heating and hot water.

Thats how it works:

The water heated by the algae flows into a heat exchanger. Here, cold water is warmed up by the water what is heated by algae. The cooled algae water flows back into the facade. The heated water is used for heating and hot water.

Further applications of microalgae:

In Nantes, France, scientists are working on using microalgae to produce bitumen, which will allow to built our roads without oil in the future.

The microalgae platform AlgoSolis in Saint-Nazaire in France was inaugurated on 25.06.2015. Here, microalgae are cultivated on an area of ​​1840 m2 and researched by scientists.
The microalgaes are enriched with CO2. Among other things, the production of chemical products for industrial applications is being researched here.
