solar tower power generation (Mega Project)

[sen-no-sen]

A small detail bothers me all the same.

Balancing air coming from the ground at an altitude of 800m assumes that it is not completely at room temperature at these famous 800m.

I just did TILT with the previous message.

What is at the top of all these pretty towers? A superb panache !!!!!!!

There is a risk of creating a micro climate which will ruin this great adventure in the case of an agricultural suit.

A lot of engineers will spend sleepless nights there and it will not be completely neutral for the local climate.

The solar convection towers will be located in desert areas with very strong sunshine, so it will be relatively dry air.
Given the temperature delta between the base and the summit as well as the height of the tower (1 see 1,5 km) there will not be sufficient condensation phenomenon which could create any micro climate.

The creation of micro climates or even rain is the subject of other research, but by means of vortex towers bringing into contact the soil air voluntarily charged with humidity with altitudes of the order of 5000/6000 meters.

Hello, in fact it was not on the net, but an old document of the mine while being in training course in a workshop of the mines in moselle is, unfortunately this document is in their archives, it was consulted by students in engineer, so I took a look at it by chance

I have already heard of this, in fact, I believe that Areva and its technicatom design office had done research in this direction but had quickly concluded that it would not be very wise to develop such a device given the low yield.

To create a fairly powerful updraft, you need a fairly high height (the Australian and American project is almost 1000m high!) In order to allow the connection between two layers of air with a sufficiently high temperature delta.
On the other hand, it is imperative to have a "collector" (greenhouse) to heat the air on the ground.

Hello, in fact this is what I had already understood at the time, being young when I saw these old documents which speak of the exploitation of the drafts of the air-cooling towers

in fact these drafts were not powerful enough, a chef for laughs had said that for a toy wind turbine it would work very well with a mini alternator to supply the "emergency" night light of the neighboring building

A pdf on the solar tower project in the United States in Arizona:

http://publications.solar-tower.org.uk/2011_oct_Enviromission.pdf

The device should be 762m high with a power of around 200 MW.

I would like to know (but I did not find anything on the site), the yield per m2, not to mention the cost, it would surprise me that it is generally more interesting than PV for example.

At the same time it's beautiful and original, but I think that's it.

On the other hand I said to myself that in the mountains, like at home, it could be worth the cost if there was only to put a tube along a cliff with the "greenhouse" at the bottom, but unfortunately we is faced with a problem of floor space.

The cost of a 1000-meter high solar tower would be around 300 million euros for a power of around 200 megawatts.

The difference between such an installation and solar PV lies in the lifespan (more than 100 years) and in the H / 24 operation.

Either 1500 € / kW installed ... while nuclear power is (at least because with the EPR we will surely exceed 2000 or even 2500 € / kW) at 1300 € / kW ...

Exact, more the solar convection towers are the least effective solutions in the genre because they use only the phenomenon of convection and the chimney effect, which reduces them to simple tubes of giant stoves ...

Vortex lathes will have a higher yield (about double) for a lower cost ... rest industrialists to be interested in all this ....

Well the problem with us is:

a) the ground grip (not to mention the impact on the air !!)
b) limited sunshine!

In short, solar towers are like concentrated solar: this has its place in the desert or semi-arid region ...
