Retain Water

11/24/2010 7:09 AM

We can find a way to restore water coming from the dam. For this we have to find a way to bring back the water releasing from the dam to itself. In this way we can produce more electricity and water can be used for some other use.

Oh dear....
To return the water to behind the dam will take more energy that the water generated when it flowed out in the first place.
By all means use the water for irrication, cooling,etc, but you can't sensibly get it back into the reservoir without using more energy than you created.

Simple. Just pump the water back uphill at night. If it's dark, the water won't know it's going backwards up the hill and will ignore gravity. Maybe you can generate the power to run the pumps with wind energy, since solar power is out of the question at night.

Del is right, the net energy required makes this impractical on all but the largest scale. See below:

Build another dam downstream from the first and create a second reservoir and power generator.......a second round of electricity from the same water! No pumping.

Hello Johan Reji:

A possiblity exists should the water from the dam be cold enough to supply cooling to ambient heated recycling gas pump.

Some time back we develop

ed the DaS Valve a gas pressured possitive displacement pump, that is made of pipe and tennis balls for easy construction.

The process works by gas pressure build up attop water in a clinder drives the water out. The hot gas then escapes to cooling and is venturied back into the system where the gas rises to the top and begins heat expansion again.

Sorry dont have Blueprint of DaS Valve alone anymore, it being further developed into Turbine Drive and Internal Combustion Engine.

(One day I will master the Computer and get the picture in the right spot)

Should you have E-mail can post across.

Cheers

Peter

What - like one of these, perhaps?
