Ask HN: Link to project to build 10,000 5km towers to fight climate change?
I've tried searching for the website for a while and had no luck, I've found it a few months ago through HN.
Basically it's a website about an idea to build a lot of kilometer high towers that would cool areas around them and provide a lot of power and basically "stop climate change."
The website had calculations about the effects of different tower sizes, diameters etc.

Big chimneys don't work like they describe. While the air ascend in a very tall chimney the pressure and the temperature decrease adiabatically. (In small chimney you can ignore this effect, but a 5km chimney is very tall.) If you want to combat global warming use real science.
- mstipetic 9y agoYes, that is the one, thanks! Great discussion there also!
