A concept to turn the Eiffel Tower into a giant green wall has been proposed as a symbolic statement of "the reconciliation of nature and mankind."The plan calls for 600,000 plants to be attached to the structure using hemp sacks filled with soil as the growth media. An irrigation system comprising 12 tons of tubing would be used to provide water for the plants.
The installation would not be permanent, and would be removed after a few years. But, once in place, the installation would help remove an estimated 87.8 tons of CO2 from the atmosphere.
"Should it not be the duty of engineers to imagine a new future where nature is brought back into the heart of the city," said a statement from Ginger, the company behind the proposal. With an estimated cost of nearly 100 million dollars for the project, that's more than a million dollars per ton of CO2. Hardly the most cost effective carbon sequestration, but certainly a visible one.
