To laugh a little!
I did this for students!
but it's better to use recycled water!
the mini hydroelectric plant
You have probably seen it before ??

Chao!
Micro Turbine and tap water energy?
Hello,
in the same vein there is also this realization which is not bad (but there it is a question of waterfall):

I just had a look on your site, and it's really great !! on the other hand I did not understand too much, your mill will not work 24/24 is that right?
In any case it is really not bad, there can be something of this kind has to make for the robines of the house which would provide a little more current.
It is true what a compatriot said above, it is preferable to use one of this way for powered a hair dryer or other but I do not believe that this is really feasible.
I would have a few questions to ask someone who knows a bit about electricity because there are places where I can still dry a bit, if someone would have time for me in MP this would be great!

Hello
I came across this forum by looking if something existed to recover the pressure energy from tap water ...
I like the turbine shown by Renaud67, it maintains the flow but uses the pressure and can therefore be used to fill for example a bathtub (the pressure does not matter then, only the flow counts).
You talk about the problem of pressure loss at the valve outlet;
as for me, I was thinking of a solution that would allow this pressure loss to be regulated, in order to convert it entirely (to the nearest yield) into electrical power.
Let me explain: it would be possible to use, for example, an axial turbine with variable blade incidence, coupled with an all-or-nothing valve. When we open the "valve", we open the valve fully and we act on the incidence of the blades.
For a small flow, the blades have a very strong incidence: the turbine turns quickly, it converts a large part of the energy of the water into electricity: the water leaves with a small flow.
For a large flow, the blades are feathered: the turbine does not turn, the water retains all its energy.
This requires a small mechanical device for the orientation of the blades; nothing complex (for an industrial plastic manufacturing for example).
But you can also use a fixed turbine and regulate the generator current to control the flow.
Such a system would make it possible to use the pressure drop of the water, normally lost in heat in a simple tap ...
On the other hand, the exploitation of the electrical energy thus created remains to be defined Put a battery, an inverter and synchronize to the EDF network? A bit complicated ... Powering the bathroom lamp (LEDs for example)? ...
