Here is a ProGird multi-criteria assessment of solar towers at Vortex(work by Canadian Louis Michaud)

It's not easily "digestible" in English ...

By cons there is a lot of info here: http://vortexengine.ca/AVE_Process.shtml

I'm joining Highflyaddict.

The Coriolis forces that govern the rotation of the water in the bathtub when it is emptied are an absolute myth.

It is gravity and shape, initial conditions and a little viscosity that govern the direction of the vortex ...
The inertial forces of Coriolis, at the speed of water, are of the order of 1 / 100 of the forces of gravity.

hi Remundo
Coriolis forces strangely resembles an effect of the type
gravitational according to Newton's principle.

a mass which acts on another mass.
apple and earth.

For the Coriolis forces,
you have a gravitational effect
(a mass which acts on another mass)
to which is added a kinetic moment.

So you have a remote effect on all the masses and the rotation is initiated by the angular momentum.

Coriolis forces are a gravitational kinetic moment.

(the gravitation motor (17 ??) was invented a few years after Newton and its principle)

Hi Hic,

the Coriolis forces are a manifestation of the non-Galilean character of the terrestrial frame of reference.

They have nothing to do with gravitation and are not forces exerted by masses on other masses.

Okay i won't finish the topic today :|
it is the variation of the state of the water in a bathtub
, from static to moving, which causes the effect

I'm not going to start this: Terrestrial repository

absolutely.

Coriolis forces manifest for objects driven by relative speed in a non-Galilean repository in rotation compared to a Galilean.

For the forces to appear, these two conditions are necessary.

Otherwise, as Highflyaddict suggests, the effects of Coriolis are weak compared to most other forces (gravitation, Archimedes ...).

And above all, as forces strictly orthogonal to the velocity vector, they do not bring energy to the flow in the terrestrial frame of reference.

The Coriolis force without mathematical formulation incomprehensible for the non matheux, translates the fact that without force, an object goes straight while the earth turns at the equator at 2000Km / h !!
So in addition to the centrifugal force which pushes to go in a straight line and which decreases the terrestrial attraction to the equator, passing from the equator to the pole, our real speed must decrease by 2000Km / h, also forces are necessary and in particular that of Coriolis which pushes to keep the speed of rotation while going faster than the ground, when one approaches the axis of rotation of the ground, perpendicularly like the centrifugal force.
The Coriolis force has a centrifugal force component due to the fact that going east our speed is added to that of the earth and increases the centrifugal force!
http://en.wikipedia.org/wiki/Coriolis_effect
http://fr.wikipedia.org/wiki/Force_de_Coriolis
It is good to describe mathematical formulas in concrete words.
So it's an inertial force almost identical to the centrifugal force, with a slightly different geometry !!
Gravitation has nothing to do with it, except forcing us to stay on the surface of the earth.
