Air Trees in Madrid Will Produce Oxygen and Energy

inhabitat.com — The “Air Tree” pavilion is to be built from recycled materials and will be 100% energy self-sufficient. The “tree,” using photo-voltaic cells, produces a substantial amount of energy, which is then sold back to the local electric companies, the profits being used for maintenance of the structure. The second byproduct is of course oxygen.
