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.
