800 dams over 000m and 15 million m3? I didn't think so much!

Let's say at 12 m deep (since 15 m high minimum and I assume that there is more dam of 15m than 200m), 3 million m3 ca represents what surface? 25 ha ... or a 500m square ...

Ah yes it's still great!

To make it simple 1 Hectare = 10 000 M² or a square of 100 M on 100M
For the surface a simple multiplication by the height = Volume M3
So 800 dams have just 000 Ha of surface = it is the surface of a country of 1 Km² country type find the error
So it is millions of hectares of land that the 10 billion inhabitants will never be able to develop for food : Cry:

Your calculation is good except that I just estimated that it was rather in the 25 ha per dam since a large dam is at least 15m AND 3 million m3 ...

800 000 ha dams is therefore ... 25 km200 !!

35% of the surface of France ... It seems a lot to me anyway ...

Oops mea culpa: I completely zapped the "of which 52 are considered to be large dams" :D so divide this figure by 800/52 = 15 ...

200 / 000 = 15 km², it's more reasonable, but it's still a lot!

ps: you don't read well either : Mrgreen:

My calculations are correct> I have counted on 800 Dams of 000 Ha in area so it is the area of ​​a country of 1 km ² in the smallest case : roll:
You think that I did not want to go into details because it would take me 1 week and the super computer that has just acquired a certain Administration, because the calculation is anyway impossible having no information (reliable sources) but you forgot many points.
But I just have info on some in France including 1 particular (of which I saw making the model at EDF's study and research office and playing with it, then working on the dam itself and know the trades which realize it so i have some crisp details that i could surely develop if by chance i'm not sidelined : Lol: )
Example the numbers of deaths pouring in concrete> in France and a few others further : Oops:
The various defects therefore suffer certain dams in France> which are surely identical in others
The various games of musical chairs, and the various pressures etc ......

It is not false!

No but hey: we must stop looking for perfect solutions ...

I still prefer concrete that retains water rather than neutrons and alpha, beta and gamma radiation... and other filth that can be found in a nuclear reactor ...

there is much simpler> reducing our consumption would be a start, because traveling through France and sometimes other places the night is no longer the night
When you see millions of bulbs (in France) which are still not low consumption you can ask yourself the question of why?
Just at home (for years the staff have left the light in the offices and PC screens to make it simple and not to list the devices turned on : Shock:

One does not prevent the other ... quite the contrary!

Except that energy savings are a vast debate and of which many actors are in fact hypocrites ... starting with the governments which, to balance "their" virtual and fraudulent * budget, cannot absolutely not do without massive consumption of energy with high added value !!
