It started out with an article in Red Herring.

The prototype is to be installed at the base of the chimney of factories expelling the fumes.

The size of the heat absorbing surface is more important than the diameter of the chimney.

And what I want to show you is actually this is one of the components of it that we've just recently been testing which is a solar chimney we have got 17 of them now put around New York at the moment that passively draws air up.
