Generating electricity using the current Sanitary Sewer System infrastructure.

The average U.S. home uses 400 gallons of water or so a day. 300 or so goes down the drain. multiply that times even a small city of say 400,000 assuming four people per household and you end up with 30,000,000 gallons of flowing water a day to work with, that is already being collected and directed. This potential runs under the streets of every US city. We have built large Sanitary Sewer System systems. They are designed to consolidate in to larger and large pipes that flow at high rates of speed. So I am suggesting that where applicable we build generator plaints driven by this waist water. [Interesting to note is that water flow increases during peak electrical demand.]

    It is a very good idea.

    However, why do not we reduce invalid (harmful) happiness
    to save much more energy easily?

    Now with a septic tank you can add a methane generator to it, and that may be something the sanitary companies already doing at an industrial scale.
