We have a fairly extensive subject on the works of Nazare here: solar-photovoltaic / solar-tower-aero-Central-aerothermal-by-edgar-nazare-t7015.html

The vortex and venturi effect will improve efficiency but the cost is certainly more important than a straight chimney ... in particular because of the turbines which must be "high" ...

SAY VOUAR ???

Wouldn't it be high time to put a few billion € of superprofits from the MWh (electricity and gas) that have been (and will be) reaped since the energy crisis in this kind of sustainable projects?

ah the good old topic of the draft... : roll:

I never knew if it really held up.

I reassure you, it holds up if the capture surface is sufficient: that's how wind turbines work (less well in terms of overall efficiency)... right?

Disfiguration of landscapes, surface area per MW much higher than nuclear power plants, irregular production, unreliable, more mismanagement. The pigeons have not yet understood where the money comes from that finances this kind of uselessness, or else they are masochistic.

On Wikipedia I read:
"The first operational solar tower is that of Manzanares (Spanish city). [...] At the time, the cost per kilowatt-hour of the plant was five times higher than conventional thermal power plants." She ended up shattered by a storm.
"Built in Mongolia, near Jinshawan, a 200 kW power station entered into operation in December 20107. [...] The power station costs 208 million dollars. However, according to Patrick Cottam and Rudolf Bergermann who visited the site, the plant is never operational due to manufacturing errors". Or flaws in principle!

You won't find anything interesting by scavenging past renewable projects. If there had been miracle solutions, it would be known. Aren't you an engineer? Find valuable new ideas! : Idea:

Pov type ... there are tons of good ideas, but there are billions of lobbies opposite!

CO2 will disfigure many more landscapes in fine!!

Quite agree, moreover to say that we are going to put billions of superprofits (because they would be “superprofits”) in crap stuff seems particularly ridiculous to me.
So certainly the French are idiots .... But is there in the world a significant example of these tricks?
Even the Chinese, who try absolutely everything, can't show one?

In 20 or 30 years, wind and PV have made phenomenal progress in terms of performance and cost, leaving the rest of the alternative renewable generation technologies behind. Which are also often very limited in performance, even theoretical.

As for the appetite of the populations to have this type of tower next to their homes, with the immense neutralized surface, I have some doubts.

The kind of stupid thinking, more conspiracy.
Considering how much money there is to make with a good idea, if there were any, we would immediately see them pass into reality. Good ideas, there are none, because quite simply, the solution is not simple. We are waiting for you (no I'm kidding).

CO2 will disfigure many more landscapes in fine!!

And a Nostradamus-style prediction. Do you ever try to be constructive? For my part, I did not find the trick for clean and cheap energy, but at least I tried, I went back to physics and I have my little "lab". Apart from complaining about everything and showing you are incapable of distinguishing the wheat from the chaff in terms of energy, it is not very clear what purpose you are used for.

This is what they did in Mongolia: 208 million dollars for... 200 KW! : Lol:

If we multiply the cost of the Mongolian tower by 19000 to reach the price in this techno of an energy of 3 MW equivalent to that of the Flamanville EPR, and assuming that the towers produce continuously at this power which is surely not the case, it depends on the time, it would amount to paying 3952 billion ! Even if Flamanville exceeded 30 billion, which is unlikely, we would still be more than 100 times a winner compared to tower technologies!

3952 billion, this is the cost that Christophe would ask to replace Flamanville. And the same incompetent environmentalists who would like us to build this kind of tricks (sleight of hand) are the first to hit the cost of the EPR, which is still late in Flamanville. : roll:
