As I said in a previous post (about magnet and steel marple), my students are newbies in physics and all I want to show them is that there is a "position energy" (potential in fact but I don't have to use this word because they are too young ;o)).
If the water fall one meter high, I got less energy than if it falls two meters. And that's all ...
So I think you can make a non realistic simulation with a very poor model because we don't need here to have the true angular velocity and the good number of lightning LED ;o))
Thanks in advance,
