The length of Planck is enormously small, to the point that to study the microscopic on this scale it is necessary to realize an accelerator at least of the size of our galaxy and using all the energy of this galaxy !!!!!
http://en.wikipedia.org/wiki/Planck_length
However, one recent proposed vein of research in 2008 called for constructing Beowulf computer clusters to enable investigators to model particle accelerators having energy outputs equivalent to those of entire galaxies. Such models might be sufficient to simulate the probing of Planck length scales (P. Doyle, University of Maryland). [Citation needed] Incidentally, such models might also make it possible to simulate a hypothetical Kardashev Type III civilization.

Between the microscopic currently studied one hundred thousandth of the size of an atomic nucleus and the length of Planck, there is an unknown world, as much as between our earth and the whole galaxy !!

Ok, thanks for his clarification dedelco, back to the original subject please?

Edgar Nazare aerothermal power plant: 250 to 4.000 megawatts of fuel-free and pollution-free electricity
by doctorix

Thursday March 21 2013

This plant can produce a kilowatt of electricity at a third of the price of a nuclear kilowatt, and twenty times cheaper than photovoltaic or wind kw.

In addition, it does not require looting African countries like nuclear power, no more than going to war there under false pretenses that fail to deceive anyone.

The principle is simple and brilliant, just like its French inventor, Edgar Nazare.

This is one of the 48 "Cursed scholars, excluded researchers" listed in the excellent book by Pierre Lance under this title by Guy Trédaniel, which I recommend reading.

Imagine a kind of chimney, widely flared at its base, from 300 to 600 meters high. What was difficult to design 50 years ago is now easy to achieve when building towers 800 meters high. In addition, the shape of the structure is extremely stable.

At the circular base, and around the entire perimeter, air inlets, in which wind turbines are placed. The base of the tower is surrounded by a greenhouse blanket.

Under the effect of solar heat (and the thickness of the structure makes it possible to store it during the day for the night), a temperature gradient is created between the base and the top, admittedly modest, but which makes it possible to obtain a few megawatts per chimney effect.

It would be of little interest.

Fins placed inside this chimney make it possible to make swirl the air flow in the direction of the forces of Coriolis (depending on the hemisphere) so as to cause a vortex (it is this vortex which one observes in an empty sink).

This vortex gains speed and strength as it progresses through the chimney, which multiplies the power delivered.

It would still be nothing if the whirlwind did not continue to rise in the air like a tornado. This artificial tornado can climb to more than 6.000 meters above sea level (and maybe 10.000), and everything happens exactly as if we had built a chimney of this height.

(It is actually a self-priming artificial cyclone generator).

There, the temperature gradient (delta T) between the ground and the top of the tornado can approach 50 ° C.

The ancestry linked to this large gradient, combined with the vortex effect, produces a wind power at the level of the turbines capable of producing the following powers:

242 megawatts for the 300-meter tower, 1.403 megawatts for the 600-meter tower if the Delta T is only 30 ° C.

691 megawatts for the 300-meter tower, 3.981 megawatts for the 600-meter tower if the Delta T is 50 ° C.


Knowing that our most powerful nuclear power plants hardly exceed 1.500 megawatts, and that the world average is at 750 megawatts.

It is a beautiful instrument of peace and happiness for humanity, when oil and nuclear are factors of war and misfortune.

When a nuclear power plant takes five years to build, the Nazare aerothermal power plant only takes two.

The cost price per kilowatt is three times less than that of nuclear kw (and therefore 20 times less than that of wind or photovoltaic).

No delicate maintenance for this ultra-simple power plant, no fuel to buy (and therefore no wars of conquest).

Works best below 45 ° latitude (Bordeaux).

Obviously, no pollution, no risk for the populations nor for the (rare) workers on the production site.

You will find all the useful details here, with a much greater technicality, I just wanted to make the presentation as simple as possible to understand.

http://quanthomme.free.fr/energieencore/carnet14.htm

Edgar Nazare was an aeronautical engineer, graduated from the school of civil engineering, among other titles that you will discover in this article, towards the end, where he details his invention.

Nothing wacky, therefore, and its calculations are reliable a priori.

Here is what he concludes with, and you can thus judge the man:

"In the near future, if men, in their madness, do not come to destroy everything, things will change: we must inevitably tend towards the predominance of electricity that we will have almost free of charge compared to what it will produce costs us via fossil energy (he wrote this before nuclear power, therefore, probably in the early 50s).

The men of the next generation (! !!) will wonder how those who preceded them and brought what they have, did not see that there was something else to do than to take so much trouble to dig holes in the earth to make it unlivable, while this energy, they have available around and above them in a sky that shows us the example of purity ”.

Alas, Edgar Nazare had foreseen neither the madness of men, nor the rapacity of the nuclear lobby which hastened to bury his invention to better pollute the planet and ransom its poor inhabitants.

In the article you quote, Christophe, it is mentioned that it is necessary to take into account the Coriolis effect to initiate the vortex: I find it hard to believe that this effect manifests on this scale ... What do you think?

On this scale, the Coriolis effect has no impact, it only has an impact on very large phenomena such as cyclones.
The vortex is in no way initiated by this effect but by convection coupled with the geometry of the partitions (spiral) and the air acceleration at the level of the Venturi neck.

Yes, this is what seems fairly obvious to me. What my naive (falsely) question implies is the seriousness of the claims about the multiplication of the power of the updraft due to the vortex (not concerning the reality of the phenomenon, but on its magnitude).

This is "mainstream" journalism ... The way of the people, it is marked above :D : Cheesy:

I also don't think that the Coriolis effect starts anything in a vortex tower (besides that's not quite what the article says ...) but it must still be perceptible (it all depends on the accuracy of the measurements) on a tower several hundred meters high ...

So it is logical that the tower is built in the direction of Coriolis according to the hemisphere * ...

All pilots with a few hours of flight have already seen rain "spinning" a few hundred meters above the ground ...

* That is to say, when viewed from above, the direction of the anti-cyclone is clockwise in the northern hemisphere (a depression turning counterclockwise when viewed from above in the northern hemisphere)

Which corresponds to the above plan ... (except that it is in American projection ... Since the view from below should be above ... mea culpa the projection is good, only we do not see well the Vortex which should be dotted)

Yes, this is not the actual priming that this Coriolis current would be located, but it would influence the direction of the blades inducing it ...
I'm not sure how the height of the chimney would affect this phenomenon?
Are you sure that the movements of the columns of air carrying rain really turn in the right direction?

Bin Coriolis is only noticeable for phenomena of a few hundred m in size ... which is compatible with Vortex towers ...

The bathtub which empties in one direction or the other following the hemisphere is a popular false belief ... on the other hand I do not really know what phenomena and parameters are at stake in this case there ...

ps: I edited my previous message ...

Uh I think so ... but not 100% sure ... In all weather logic we should have:

a) The rain falls while spinning in the direction of the depressions (anti-clockwise view from above)

b) The rising air columns (I'm talking about thermal or mac) rise in the direction of anti-cyclones (timetable seen from above)

Finally by making a good 3D projection: it follows the same helix so it's "logical" : Cheesy: : Cheesy:

And the trick question: which tornadoes are turning in what direction? It is air that rises in a low pressure phenomenon ... : Cheesy: : Cheesy: : Cheesy:
