It is one thing not to neglect any solution, starting with the best is even better.
The sun is relatively predictable and stable in the Mediterranean, a fortiori further south, and it can be stored in thermal form in industrial-sized "thermos bottles". We could thus start the vortex at will.
However, the "vortex-effect" tower is nothing more than a thermal machine between a hot source and a cold source.
The hot spring is solar and of very poor quality (at most 60 ° C at the bottom of the tower). The cold source is hardly better: 0 ° C, a little less in the upper atmosphere: it is this coldness that we wish to benefit from by a vortex of gigantic height (whose formation, control and stability are very hypothetical ...).
That said, even assuming we can initiate and control the vortex, the air stream generated can carry away in mechanical form only a very small fraction of the thermal energy which gives rise to it ; with turbines behind, limited by the yield of Betz, we will recover mechanically surely less than 10% of the solar power collected. The maximum theoretical is even (1-273 / 333) * 16/27 = 10.6%
The vortex is thermally only a gigantic current of heat which transfers calories from hot to cold: or mechanical sampling is only valid if there is a large deltaT between the hot and cold source.
To put forward the "vortex and Coriolis" is a certain mystique: although present, they will not change anything at the limit of Carnot and that of Betz. Which will dramatically limit the mechanical efficiency of a hypothetical artificial tornado?
On the contrary, with concentrated solar power, today we obtain 30% with deltaT of more than 600 ° C, and thermodynamic solar energy has not said its last word.
Well, I may not be understandable by everyone, but I take care of myself
See you soon !
