Why plant trees when you can install glowing treepods?
SHIFTBoston and a pair of Paris urban designers have come up with an idea for treepods that would not only filter carbon dioxide out of the air but use solar panels to generate the electricity needed for the filtering and for displaying "colorful light during the evening." A seesaw at the base of each tree would provide a fun outlet for visitors and provide additional energy to the trees.
Their design is based on dragon blood trees, which, in addition to looking like something out of Avatar, provide a large number of surfaces for bringing in carbon dioxide.
