My hydraulic mill 400 houses?

(twice water police (ddh) agents came to take photos and record flows of water and photos good to see later.


Already it is not the width of the river that counts, but its flow.
Then, and you must know it since agents came to your home, even if you have a water right you have no right to take the entire flow for your mill.
With a "standard" mill (say a wheel 1m wide and 5m in diameter) if you can support the consumption of 4 houses whatever the period and 365 days a year that would be good.
I think you do not realize the poor performance that has a paddle wheel ... (which must still be subtracted from that of the generator)

I did not study more than that the video ... But the type in question (I am not sure but I believe that he is or was a member of this forum) put this mill back into service and today injects electricity back into the EDF network ... He invested at least a decade of his life to get there and a nice bundle of cash ...

And indeed there is an error in the calculations .... 30KWx24h = 720Kwh x 365 days per year gives us 262800 KWh x90% = 236520 Kwh annual (and not 22000 as marked on the video) or taking the Kwh at 0.11 € € 26017 of energy value produced ...

Hi snowy

The permanent power of your standstill mill is equivalent to the average flow rate of its outlet.

I am new here, I signed up on this to have possible answers on renewable energy and where we are currently in France on this point. whether these blah blah or not! because we are talking about making electricity with clean energies !!! and the water mill which is legion in France and which requires that to crack down on its next, we talk about it very can or not enough, I tell you its because I myself own a mill and which can with its flow of water flowing continuously supply at least a town of 400 see more homes. So to whom to turn to be able to assert this energy potential. thank you

It is totally true.

Small hydraulics are completely neglected.

It's true, so true that it is overlooked by the vast majority of mill owners themselves.
How many mills can we see whose wheel is not maintained, and not even in operation ... when it simply does not fall into disrepair.
Quite a few (rather affluent) people buy a mill for "style" and don't give a damn about its energy potential.
Yet without great skill and without any particular complication, it is already so simple to be able to heat your home thanks to the power of the wheel.

What factual elements allow you to reach this conclusion?

Or is this completely pifometric even the on dit from the village?

I do not know,

based on 400 W on average per house, 400 houses represent 160 W

it's not impossible, but it depends of course on the turbinable flow and the fall ...

By counting a height of 10 meters (beyond, it is no longer really a mill, but a turbine with a pipe), that would give a flow of 1600 kg or 1,6 m3 per second (to increase the conversion efficiency) .

By being less optimistic, with a fall of 5 meters and a yield of 50%, we arrive at a flow of 6,4 m3 / sec ...

It seems a lot ...

I almost broke my piggy bank for a (old flour mill) .... But I would not have had the least € to rehabilitate the turbine and manage to fit out my home in it ... But the owners did not want to sell the mill proper separate from the rest of the outrageously luxurious property complex ... It made me a little hole of 100 € to achieve my goals ... then we should have seen for the water rights which must have been lost in the administration meandres ... Since the time the factory was shut down ...

The efficiency of a very good wheel barely exceeds 30% (for the most advanced versions and with a particularly careful construction)
If you want better you have to go on a turbine.
