Step back a little. Why are there places in cities where trees "can't grow"? What's the problem - water, land, sunlight? And why not fix whatever is keeping trees from growing, and then grow trees, instead of dropping in a tub of algae? And if these tanks are 50 times more "efficient" than a normal tree, how much more expensive is manufacturing and maintaining them than planting and watering a tree is?
This feels like carbon capture technology to me - a technological patch on a social and ecological problem, meant not to help the environment but to funnel tax money to venture capitalists and tech companies in the name of environmentalism.
@stabby_cicada @MonkCanatella Lots of ideas for both algae and traditional trees in Bioshelters, Ocean Arks, City Farming: Ecology as the Basis of Design by Nancy and John Todd, both of whom are still around.
Years of links to urban and advanced agriculture at http://cityag.blogspot.com
which is also a listserv
Good looking out with city ag. Adding to my RSS reader, thanks!_Going to have to check out that book sometime, just from the title alone it sounds right up my alley
