Yes, a thousand times alas, the project is now an orphan of its designers ...
Rest of the project partners like Joseph Jacoby and Jean Nkengsa.



highflyaddict you write:

As for numerical modeling, it really predicts a vortex of 20000 m? Seriously?

Before criticizing a subject, it would be good, at least for the sake of knowing what we are talking about, except you refer above to the Nazarre / Sumatel project, which concerns a tower whose purpose is to generate an external vortex, which doesn is not the case of the project developed in this subject.

Ah! I must have read the title of this topic badly then ...

This subject is now more than 10 years old (hey yes!) ... where are the developments ??? Prototypes? Demo?

Answer: in neutral.
A small solar convection tower demonstrator was built in China, but that's it.
For the Vortex tours, nothing at the moment, it's a shame ...

Rolala ... it's very sad at a time when global warming is starting to get carried away ...

In a few decades, we won't be able to say "we didn't know" ... but we will say it anyway ...

It went very well for the Shoa vis-à-vis the allies, it will pass for warming ... sorry if the comparison offends it is willful and voluntary!

If I understand correctly, the goal is to rely on the energy of the Karman whirlpools. http://www.francispisani.net/2017/07/vo ... llons.html
Old dream of free energy, because it takes a very precise wind speed for the entry into resonance, moreover unusable energetically.
They can always make their call for donations with beautiful images and not the slightest achievement, in fact. http://www.vortexbladeless.com/technology.php

Not at all.
The principle of a vortex tower is to heat the air through a peripheral greenhouse and to make it converge in a tower where it is accelerated by the venturi effect and rotated via spiral partitions.
The principle consists in exploiting the temperature delta between the ground and the atmosphere.
This is a fairly ingenious method which is based on fluid mechanics, it has absolutely nothing to do with "free energy" tendency over-unit.
