What happens at …
What happens at nightime? No production?
How long does it takes to “warm up” the air before it flows with enough speed?
Can it be made at a smaller scale and still produce significant power?
What is the lifespan for this kind of mega-construction and what are the costs of maintenance?

where does this project stands? I checked wikipedia and there is basically no news since 2007. The company (EnviroMission) still has a (pretty) website, but not much info on it.

There are only wind …
There are only wind turbines at the base because cold air or dense air at ground surface when heated up it creates convection or it raises in that way the flow and pressure of warm air ascending is greater and more efficiently used.

I would imagine you …
I would imagine you can’t put too many turbines in there, as you want the hot air to successfully evacuate the tower to be replaced with fresh air, rather than have alot of obstructions in the tower that would clog up the air flow.

The History …
The History Channels Modern Marvels stated that it would take only 620 of these to power the US. At $700 million a pop that means that it would only cost $434 billion to power the US with an energy source that is always going to be here.
