OK they are blowing air up. How is it powered? Why does it look like Sasha Grey's @%$^%#? How much damage is being done by creating the power? Is it cool air which will drop or warm air that will rise? So many questions.
The building at the base is a glass enclosed, so sunlight warms the air in there, which then rises through the chimney. Which is full of filters.
I guess they take the filters out periodically and dump them in the landfill.
Considering that China is building Hundred's of new coal fired electrical plants this is like using a single paper towel to clean up a major oil spill. Whole thing is more for show than anything.
