I came across some eco-friendly walls from Patrick Blanc a couple years ago. He'd covered a building in paris with a massive vertical garden. It basically turned the entire building from a concrete structure to a green wall that removes CO2 and creates oxygen.
I thought it was fascinating. I recently came across http://www.livingwallart.com that has these eco-friendly vertical gardens that gave ideas as to how to install these in your own homes.
What do you think? Would you use this in your home to reduce CO2 and create more oxygen?

I've been watching the development of this "technology" with interest, but there are other even more beneficial aspects that these types of systems can offer: cooling in the summer and screening the cold wind in the winter. Some of these systmes have had problems with their irrigation system and have died out.

I've also implemented a very low tech version of this at my house: it's a 12' high trellis a foot from the extrior on the west side of the house with evergreen ivies and vines growing up it. It lowers the local ambient temperature and blocks the harsh evening sun in the summer, and blocks cold winds in the winter.

there is an architect from Japan who does great things with integrating plant life with the built environment. I completely forget the guys name though. The use of building integrated vegetation is on the rise.

Why go with a big system. Boss's idea of a trellis with a drought tolerant perennial should do the trick. I don't see why we have to make this more complex by creating high tech systems that emulate nature when nature is still here and often times cheaper.
