It’s a good job that these vertical forests in Nanjing, China are going to produce 132 pounds (60kg) of oxygen every day, because they’ll literally take your breath away when you see them.
They’re called the Nanjing Towers, and once they’re complete in 2018 they’ll be Asia’s first ever vertical forests. Designed by Italian architect Stefano Boeri, each tower will stand 656ft and 354ft respectively, and between them they’ll house over 1,000 trees and approximately 2,500 shrubs from 23 different local species. The taller tower will contain offices, a museum, a green architecture school and a rooftop club, while the smaller tower will house a rooftop pool and a 247-room Hyatt hotel. Balconies will afford visitors stunning views of the dizzying vertical forests that are intended to help regenerate local biodiversity. These aren’t the first vertical forests that Stefano has designed however. Two have already been built in Milan and similar buildings have been planned for Lausanne, Switzerland. In an increasingly polluted world, these green designs are a real breath of fresh air.
Artificial Photosynthesis Projects
However, a number of recent breakthroughs offer promise.
Scientists at the California Institute of Technology created a lab-scale device that converts 10% of the sunlight received into fuel.
Other researchers at the Lawrence Berkeley National Lab and the University of California at Berkeley say they’ve created a system that can capture carbon dioxide emissions before they’re released into the atmosphere and convert them directly into fuels.
Their system uses an array of tiny silicon and titanium oxide wires studded with a bacteria – sporomusa ovata.
The nanowires capture sunlight and deliver it to the bacteria, which in turn convert CO2 into acetate. Acetate is a key building block for more complex organic molecules.
The efficiency of the system, however, is currently only 3%.
More promising is research from Monash University in Melbourne, Australia that’s focusing on generating hydrogen for fuel cells.
Their process closely mimics natural photosynthesis, using solar energy to convert water into hydrogen and oxygen. One key difference between them and the others, however, is that instead of using expensive precious metals as a catalyst, their method uses common (and cheap) nickel.
And energy efficiency came in at an impressive 22.4%. The prior record was 18% efficiency.
Similar buildings have also been planned by the architect for Lausanne, Switzerland
And two vertical forests, called Bosco Verticale, have already been built in Milan, Italy
In fact, over 80 per cent of all prefecture level cities in the country (the administrative division below “province”) have at least one ecocity project in the works. Over the coming decades, it has been estimated, 50 per cent of China’s new urban developments will be stamped with labels such as “eco,” “green,” “low carbon,” or “smart”.

If food is going to be grown insecticide?
Container gardening is water intensive.
Who or how do you trim this?

I think it looks beautiful and the vision is creative, I wonder at the reality. The weight of tress, all the roots, the logistics of maintaining proper care. What about the winds? A falling tree limb would be disastrous below.
I wonder if we can design new plants or find other options that would work better for this situation?

There is a danger to it.
Over doing it will increase 02 levels, and increase fire damage.
Just because I'm not a fan really doesn't mean anything.
Perhaps, but surely that will be considered in design.

I gotta wonder about the negative aspects on the building structures long term.
Anyone that does home maintainence knows how much damage plant life can do to a structure.
