Biggest wind turbine in the world in 2009

[RIAZ]

Much ado about nothing in short this jancovici ...
Criticizing is very easy, proposing something worthwhile is another thing ...

Indeed, it is better to laugh!

People who do not understand what JANCOVICI is saying have in common the lack of mastery of basic arithmetic and the belief in Santa Claus.

Hello

large wind turbines, it's not new!

it's great all the same!
To have the power of a nuclear reactor, you would need a pack of these monsters!
But in some deserted areas why not, and there is no shortage of them in France!
On the other hand, at 100 m, a vortex tower would have a much higher power (X30 according to the lowest forecasts ...) provided that it is built!

Centralization has already proven itself and, conversely, decentralization not yet.
Personally, I do not agree even if it actually reduces GHG emissions. Moreover, the requirements in this area are far from being met by these giant bat choppers.
But we are used to measuring in Belgium at the cost of reforms.

At the end of the 50s, a wind turbine was built in Nogent le Roi, in Eure-et-Loir, it operated for a very short time because no one had thought that exceeding the speed of sound at the end of the blades would cause their destruction. The info was kept secret and EDF dismantled the "aerogenerator" declaring that the experiment was over.

It's a bit affirmative as an explanation. See my site dedicated to this wind turbine http://eolienne.cavey.org

1- it is not because the tip of the blades reached the sound barrier that the propeller broke: it had approached these speeds on October 27, 1959. The nominal speed at the blade tip was Mach 0.45 with the second propeller (the one that broke). The rupture is due to mechanical fatigue as a result of self-sustaining vibrations,
2- it is wrong to write that "nobody had thought that exceeding the speed of sound at the end of the blades would cause their destruction". Lucien Romani knew this perfectly and so did my father,
3- I am very critical of EDF about this wind turbine but not to the point of writing untruths such as "The info was kept secret" and "EDF dismantled" the wind generator "by declaring that the experiment was completed ”. The info was not a secret: all residents of Nogent could see the damage and the wind turbine remained as it was for three years! Never has EDF asserted so peremptorily that the experiment was over and the decision to stop the tests was taken long before the wind turbine was dismantled.

The subject is too serious to let legend or hearsay take precedence over the facts.

A beautiful photo report on the construction of the world's largest offshore wind turbine at Le Carnet, near the Loire estuary, 6MW; Haliad, from Alstom.

Awesome!

thank you, it allowed me to read well.


I laughed when I saw this picture

The site Oleocene seems to have his pendulum stopped since June 2010.

Centralization has already proven itself and, conversely, decentralization not yet.

It is intellectually myopic to write this ...
- Centralization revealed its vulnerability and many other faults. It is by becoming aware of this that the American soldiers of the DARPA decided to create a decentralized military command network. They understood that an effective attack on their command center could render their formidable military power 'silly and inoperative'.
- Decentralization is what humanity knew at the dawn of the XXth century (decentralized armies, economies, energies, transport, ...)

Both systems work but have weaknesses.
Centralization has made it possible to accelerate industrial and technological progress ... up to a certain limit ... which decentralization makes it possible to overcome.

The academics who developed ARPANET quickly saw it as a means of exchange, cooperation and sharing far from the military vision that presided over the establishment of this network (The USA was in the midst of a hippie wave, against the tide of the problems of the military, stuck in Vietnam War).

The decentralized network is considered to be intelligent, responsive, capable of more easily freeing itself from "single thinking".

150 years ago, windmills and water mills ensured a complete network of French territory. In the flat Landes department, each stream had a mill every kilometer, 2 meters of reservoir sufficient to feed it.

Today, we know that by covering the roofs with solar panels, we cover, in absolute value, our energy needs easily. The addition of a small 300W wind turbine allows in some places to provide as much energy as 20 m² of photovoltaic panels (for 10 times cheaper).

Finally, decentralization is the return to the stated "common sense of the peasantry" on oleocene in these terms that I like:

I hope to see the end of the world we know, that of abundance and waste, and see the return to ... a world ruled by two economists often cited by my parents and grandparents: one without doubt Corsican: Parcimoni and the other probably Armenian: Abonescian.

We are more in a 'Pariçilamonnie' configuration, no?
