Unusual design of a free-flow hydropower station

Yes, why don't I answer if he doesn't answer.
My answer is that -  I picked it out of thin air.
I decided to pump him up - but does he understand what he blurted out?

Has it finally dawned on you that this idea is worth stealing?

But how can you steal something that is already in plain sight?

Finally the real clown is out of the bag.  :-DD

@Hydro, do you even understand how much energy is 1J/s which is 1W?

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.

Edit: I overlooked the fact that it is continuous. The small number is just the amount of energy for a single second.

To reiterate:

2. how did you calculate 1600 Nm without taking into account the pulley diameter?

The holes in your knowledge of mechanics are profound.

You don't even know the basics.

For your education, $$\tau = \frac{P}{\omega}$$
where $\tau$ is torque, $P$ is instantaneous power, and $\omega$ is angular velocity.

There is no "pulley diameter", or "lever" in the formula.

Distance from the centre of rotation does not matter.
