It came across my mind few days ago: why nobody ever bother to put a small electric generating turbine (perhaps 3 or 4 inches wide) downstream of any municipal water connections? Or perhaps downstream of domestic water container, so that any waterflow can generate small electricity to make energy conversions more effective?

I meant, look at how many hydroelectricity potencies we waste everyday? We use water everyday, for all of our hygienes and biological needs, and even to flush out our wastes. And all of that flow wasted away; its potencies wasted away!

Anyway, I propose that every tall buildings in the world (exceeding 10 meters high) must have a small hydroelectric powergenerator. The electricity generated can be stored inside a capacitor to be used intermittenly with municipal electric supplies!

Conserve your electricity, Use WATER !
