Energy-Concept:

The entire amount of energy is generated by micro- algae. In closed loops a algae-water mixture circulates trough a pipesystem inside the hotelfacade. Illuminated by the sun the organism produces not only oxygen, but also reproducing their selves. As a result the algae proportion grows continuously. More precisely- every two days the algaeproportion reduplicates itself. Harvested and filtered the algae- biofuel can be used to generate electricity by a block heating station. In comparison with biofuel from rape, harvest an be 80 times bigger with microalgae.

The bottom line is micro-algae has the ability to mass-produce fuel for 104 % of the energy requirement of hotel and wellnesspark.
