Exploitation of the mechanical energy of the rock

Renewable energies except solar electric or thermal (seeforums dedicated below): wind turbines, energy from the sea, hydraulic and hydroelectricity, biomass, biogas, deep geothermal energy ...

In this case, and in all cases where a mountain is already there, that the difference in height exists and that there are materials available on site ... why not take advantage of the configuration of the terrain to really constitute a reservoir water! You would then have an inexhaustible and renewable source of energy! And you would have enough electric power to transport the ore in the valley ...


So there you make me laugh : Cheesy: you '' econologists ''. In '' econologist '', there is ecology, isn't there? You say you are progressive and at the slightest original idea you bring out the coal power plant! An O_o hydraulic power station and what else !!!

Not only are we no longer in the Stone Age (or should we go back?… In any case Gaulois raises this question in us) but in addition it is an ecological disaster: because of the floods which destroy the local ecosystem and causes the disappearance of indigenous species, hydraulic modification by disrupting the seasonal flow which dries up the water tables and concentrates the sediments, not to mention the ecological fragmentation which blocks migration. Fish ladders you say? Might as well try to make stairs go up to an ass of a mancho bowl!

In short, I actually think that we can go over the aesthetics and build a wheel to lower the stones. After me, I am not a scientist I let you think about the problems of constancy of the flow etc ...

But hey anyway ... a hydraulic plant it was very good!

So that we don't forget the ecology (here especially the salmon!)

Excuse me Obamot if I have offended you with my spelling. I see the problem with the acute accent (which indeed had to be absolutely raised in view of the very serious extent of the fault) but on the other hand I do not see the problem of my 'logue' but I imagine that it is a scientist joke : Cheesy: . In the future try to make jokes a little less subtle the story that I can laugh too.

So much chatter, let's get back to the topic. I understood the problem of the type 'pull-buttock' system: number of pulleys etc ... and well understood the advantage of the wheel: a bearing and a large lever arm. Only the wheel is relatively bulky. I ask you the question are there other alternative systems?

After a while, anyway, if we don't break the mountains down for energy, erosion will do it for us. So while to do ...

Reshaping the Alps may seem surprising at first, but that's what must have happened in a few million years for other massifs! At worst, we can leave peace at Mont Blanc, there are enough other summits to meet our expectations for a few decades !! After all the question is: how much do we want to expect from such a solution? By way of comparison, wind power production in France is 6 TWh. It should be possible to set up facilities to produce the same order of magnitude, perhaps a little less anyway.

However, no source of energy recovery in any form should be overlooked.
I remember my grandfather, who was a farmer. He notably owned a grain silo, which he used to dump grain into tractor trailers. And he realized that he had a significant potential energy reserve, and completely untapped !! He therefore manufactured and installed a microgenerator at the exit of his silo. In fact, the falling grain drove the blades of a kind of wheel, thus making it possible to operate a coffee grinder and an electric coffee maker. That way, while the grain was loaded into the trailer, it provided enough energy to heat a coffee, and grind the grain for the next. So he could drink a coffee with the guy who came to get the beans !! And in addition it replaced the booze, it was not worse, because it booze ... Finally there is not the subject !!
Still, he had been able to exploit the potential energy of wheat to prepare his coffee! Well, it turns out that afterwards, with the cousin, we replaced the coffee maker with a horn that played "la coucarracha". It was much more fun, but much less useful as an enhancement ...
But here is my conclusion: nothing should be overlooked.

Finally, I will end on this note: it is said that "Faith transports mountains". This is exactly what I am proposing here.

Economically,

Gallic

you don't care about us with your mill at the bottom of the silo

the grain is not liquid, the grain comes out of a hole at the bottom of a 100m high silo without more useful force than a one meter silo!

the only way I know of exploiting the potential energy of the silo is to unload it with a crane with clamshell with cable, whose winch is a good electric motor well reversible: the grab takes up the silo and goes back down to bottom full, producing a little more electricity than it consumes to go up

this is the problem of bulk material, when moved by screw conveyor belt, chute, there is so much friction that it always consumes more than any potential energy

there are only frictionless things that can work: train, cable car, cable crane ...

"The mechanical energy of rock" it was aiming too high. Here it is rather "Sandbox" : Mrgreen:

Back to "hydraulic, wind, geothermal, marine energy, biogas ..."
