It's such a simple yet brilliant idea that could really make a difference.

This is interesting. I wonder if it is based in the human farms of the matrix? Kinda looks like them sorta.
I wonder what they will do with the air they produce?

These could be built in the poverty stricken areas of the world and alleviate much of the world hunger problem.

This is a positive technology towards advancement to a type 1 civilization.

Great find...off to sharing it.

This is not just another pie-in-the-sky ( pardon the pun) idea.
IMO this will soon become necessary if we are to sustain ourselves and the planet. An added bonus will be that, in general, we will become much better, more empathetic persons as we once more begin to connect to all living entities on earth in a tangible way rather than the abstract superficial way most do at present.

That's really fascinating. I like the idea, but is anyone else freaked out by the fact that we're already running out of so much space that we need to do this, and the potential for more growth that it may provide. The thought just makes me uneasy. By temporarily fixing one problem, we may end up exacerbating it more in the end, or even creating a new one. It'll be interesting to see the long-term effects this will have.

Another good way to burn up more coal to produce more electricity instead of having farms outside of the city bringing produce to market.

Overwhelmed...fascinating find!
