Agustin Otegu thinks the future of green buildings lies not in the giant wind turbines we've seen in so many other projects, nor in huge solar panels. Instead his new design proposal, called Nano-vent Skin, would incorporate tiny, biological self-repairing wind turbines into the outer layer of a building. As wind played over the building's "skin," the turbines would spin and create energy that would be fed into the building's electrical grid. They would also absorb carbon dioxide.
How would this work? Otegu explains:
The outer skin of the structure absorbs sunlight through an organic photovoltaic skin and transfers it to the nano-fibers inside the nano-wires which then is sent to storage units at the end of each panel. Each turbine on the panel generates energy by chemical reactions on each end where it makes contact with the structure. Polarized organisms are responsible for this process on every turbine's turn.
The inner skin of each turbine works as a filter absorbing CO2 from the environment as wind passes through it.
The fact of using nano-bioengineering and nano-manufacturing as means of production is to achieve an efficient zero emission material which uses the right kind and amount of material where needed.
These micro organisms have not been genetically altered; they work as a trained colony where each member has a specific task in this symbiotic process. For example, an ant or a bee colony, where the queen knows what has to be done and distributes the tasks between the members.
Sounds like science fiction, but a marvelous science fiction it is.
