GE proposes to use artificial sink to generate 500 MW of power in Southern AZ
I don’t understand the explanation of how this works. The article says
that making the air moist makes it heavier. When I was at school I was
taught that water vapour is lighter than air and that moist air is less
dense than dry air so why would making the air moist cause it to sink?
I think the people who wrote the article don't quite understand how this
works.
Surely its the evaporation that is important rather than the wetting of the
air.

You should see the solar towers southwest of Primm, NV (just inside CA),
USA. The top of the tower, surrounded by acres and acres of focused
mirrors
appears to glow white hot. You can also see a dark cloud around the
tower.
I wonder if that's plasma from super heated air or just the remains of
passing bugs and birds...

I bet desalinated water is more valuable in Arizona as
irrigation or domestic supply; unbelievable.
The downdraft tower would be the inverse of the
Australian 1km solar power tower; I have seenno news since 2011.

They said they'd pump "desalinated" water, so there's gonna be quite
some
construction and energy expense on the intake end, as well.
And a nuclear reactor wouldn't be near as expensive, I'd wager, were it
not
for the DOE. Remember, the government couldn't make a profit running a
whore house that also sold whiskey in Nevada, so why should we believe
they
make a better nuclear plant?

The first article is a technically better where it shows the
evaporative
cooling creating the down draft, so that part has been explained.
It also says the water will be brought in from the Sea of Cortez 48
miles
away. So what's the cost model for building a pipe line and pumping
water
48 miles? substantially cheaper than a nuclear reactor, I guess.
This
project would seem to be significantly more expensive than regular wind
turbines - not that we like those either.
