Air purification system based on hydroponic plants.
"Many researchers have been touting the benefits of purified air indoor plants. One of the problems: the adjustment of the leaves, since they are not as effective for the removal of toxins.
Researchers at the Center for Architecture Science and Ecology (CASE), a research group co-founded by SOM and Rensselaer Polytechnic Institute, joined forces to develop a new way to harness the power of the rhizosphere. designed a series of pots that allow fill an entire wall of hydroponic plants. With this system the plant roots are in contact with air toxins. As air passes over the roots, microorganisms that live in the roots absorb volatile organic compounds (VOCs) and other air pollutants and decompose into harmless substances. The filtered air passes through the inner air circuit installed in the ceiling and recirculated. With this system can be trimmed in VOC levels in a normal office 80%.
this in turn, reduces the need of fresh air in a building, which can reduce the energy consumption associated with air conditioning systems by up to 60%. 's still in the testing phase.
But really, the system is as powerful as the designers suggest, could be a solution to the vexing problem of poor indoor air quality - and much prettier than any purifier you can buy."
