According to the table you posted, such a hydropower station of 1m depth produces 3430 Joule per second. This is 3430W and boils down to 0,000952778KWh. Good luck in powering your house with it.

3430 Joules per second = 3430W = 3.430kW
If this continues for one hour, you have generated 3.430kWh

True, and if you only use it for lights and a fridge or so it will suffice. But if you want to run your washing machine simultaneous with your vacuum cleaner, fridge, toaster, microwave, heat pump, etc. it ain't gonna cut it. Our house has a 9KW connection, so I would need three of these "power plants" and a big river nearby. Not possible in the small stream that runs in the fields next to our plot.

As a proper solution for switching to "renewable energy" it is useless due to it being small scale, and impractical for large deployment. Large scale geo thermal might do the trick, but as with everything else, what are the long term consequences.

And on an other note, what would the life expectancy be of such a mechanical structure in a stream powerful enough to drive it. With dirt and it causing erosion I don't expect to long.

I disagree with your assertion that small scale is useless. I would consider a near continuous supply of 3kW from a clean energy source on my own property to be a huge win. It would mean low cost, low carbon hot water supply and lighting. Add battery storage to enable some higher intermittent loads. The incoming mains supply would then be used to power the highest (but short term) loads.

Yes, I don't understand what exactly is so bad about having lighting, refrigeration, computers and a few other things running 24/7 for free :-//

It's irrelevant, because you are not going to get any of that from whatever nonsense is being presented in this thread  :-//
