Hydraulics, a false good idea?

Hydraulics: a good idea?




by Wind Howler » 06/03/08, 18:25

In my younger years, I spent my holidays in the Vosges with parents who produced their electricity with a 35 hp turbine. fed by a small local torrent: a diversion, a small threshold with a weir function, so as not to dry out the stream, parallel to the torrent, on a flat field with a slight slope, a narrow earthen dam 7 meters high , inside which wild trout thrived. Everything had been very well studied, two generations before, to feed a mill without disturbing the environment. Another turbine, 100 hp, was put into service to drive the machines of their small factory during flood periods, mainly in the snowmelt.
I am amazed to see how far we have come back to the Middle Ages: municipal, departmental, governmental, ecological regulations, interventions by fishing companies; there are no longer any lords or abbeys, but both have been largely replaced. We: hypocritically complains of being "behind" the neighbors, on European regulations, on the time, on the issue of greenhouse effects as to the deployment of "renewable energies" and we do nothing to - I do not not say incite it - but facilitate or encourage it. There are fewer scruples with the insane use of petroleum fuels.

There is a tiny (and inexpensive) turbine invented in the Czech Republic which turns and produces electricity corresponding to domestic needs from a low head and low flow rates, so without disturbing the structure and the course biotope modest water. The principle is the recovery of the energy of the eddies of the streams - the egg of Christopher Columbus! it was enough to think about it! .Its installation does not require significant work. It can be used on any watercourse capable of supplying between 22 and 33 liters of water per second. This is the SETUR turbine, which, despite the interest it presents, is not yet marketed in France. This device is patented in Europe and the USA and its development has been encouraged by European grants.

The efficiency of water, as everyone knows, is much more important than that of wind, because of the density of this fluid. In addition - except in conditions of drought its direction and its flow are much more regular.

I can only go your way dear Windjammer ...

We spend our time wondering if the fish will survive, it turns out that with a reserved flow and a fish passage, they are doing very well ... I have a stream where there were two mills. 100 years. My father was a young man fishing there for trout with his bare hands !! For 50 years, the mills have been demolished ... And there are hardly any fish! All this is mainly due to chemical pollution: acid rain, fertilizers, slurry made from "dubious carcasses" (do you know animal meal?), Excessive spills of ammonitrates.

Sometimes, the same "fishermen or farmers with an ecological fiber" take their 100 HP tractor to fetch the cows or their huge 4X4 every Sunday to go hunting ... : Lol:

I know some...

all this is very nice ... but it does not bring anything
in the state and the more people are independent the less they are controllable ... the extremist ecologists do not arrange
nothing neither !

One of the main problems with fish is the birth control pill.

Estrogens rejected in the urine and not treated by the treatment plants are found in the rivers and the Pisces monsieurs become Madame Pisces, which generates obvious difficulties in terms of reproduction.

As a fisherman, I confirm that a small turbine does not generate a major impact on wildlife if its installation is well thought out (see example from Rémundo).

However, even by setting up a small stream with a few heaps of stones to encourage fish reproduction, you can be outlawed: you have to submit a plan, etc. and obtain an authorization ... While the flow before and after remains substantially identical and that the only result of facilitating the reproduction of fish!

heo!

where did you see that people had to report to the state?
Is this capitalist thought written in the fingers of man?

easy to type on the extremist environmentalists! you don't want to burn them either?

you're glad to find them when they advertise nrj news for products to be developed! while it is the state itself that is holding back!

do not make fun of it ;-)

Hum hum ... however some of your sentences go in this direction: according to you the man would be responsible for all ...

oh, there are two to hit me! : Cheesy:

for jonule:

this is a finding not an approval!

it's not the people who have to report to the state, it's the energy
they consume, the government does not have a policy
development of local energy production or even
individual (but we do what we want) ... : Mrgreen:

for tophe and janule:

I don't like extremes, even if sometimes
extremist idea can arise a compromise that makes
advance the shmilblick !!! : Lol:
and then when i talk about moles ... i laugh !!! the smiley : Mrgreen:
is made for that

in any case the case of moles is a very good biting example, I would use it again :D

as for paying for the energy distributed by the government, it is a principle either, but they would have to offer what consumers want then; renewable electricity for example.

I am rather to produce my electricity, and to become autonomous so as to consume nothing more.
good, can be resell to the neighbors? -)

the day I would be happy is when I terminate my EDF contract : Cheesy:

You know the company H3E, http://www.h3eindustries.com/pages/produitpag.html, it will please Jean63 and Remundo, she is based in Clermont-Ferrand and she has developed the Aqualian, a high performance hydraulic turbine with an efficiency of 80%:

What do you think?
