Hydro Turbine power generation.

My first accomplishment was to raise water to storage and flow back, next was to connect the hydro turbine direct to the pump. The pump itself is entirely my own design and uses gas pressure to force the water. The gas I use is Carbon-C02. However other more active gasses may be used though to date CO2 is the only one I have been able to get specific graph on as heat to pressure. But first of all back to the hydro turbine/generator. A one litre 9 bar per second 82% efficient (common) rotating at 60 RPM produces 720 watts. This increases by pressure, volume or rotation. Next the pump, this being the DaS Valve also fully developed by myself. It works on the principal that gas shall rise to the surface in liquid. A heat expnding gas pocket above water creates a water pressure exact to that of the gas pressure. This gas pressure is whats used to drive the water from the pump. The minimum 9 bar pressure requirement is reached at minus 10* Celsius, the same gas at plus 100* Celsius produces 10,000 pressure. The pump being fully sealed is 100% recycle. The complete device is constructed by cut and weld of pipe. Care should be taken in pipe strength to make sure it can handle the pressure requirements. I used line pipe for 10,000 bar pressure (720 kilowatts). The three attachments are complete engineerings of the DaS Valve, the ambient heat hydro turbine generator and the CO2 pressure to heat graph. Most happy to help further.

Hi, Welcome to the forum,

The principle would work, but I see a great loss of heat to the water during operation.

A volcanic heat source, Hot spring,etc. for the energy needed to reheat the gas would make it useable. I suppose a Solar furnace could also be used.

But I believe the heat needed to carry out this cycle would better be used to power a steam turbine. This would eliminate the energy loss from the extra cycle conversion.

There may be something here I'm Missing??

Time has proven that I am blind to the Obvious, some of the above may be True?

Hello Greenbelt,

Thank you for welcome.

The system does work hence its being published far and wide in Open Technology in order to reduce Carbon emission.

Yes, there is some heat loss to the water but that makes no difference CO2 heat expands just as readily when passing through hot water as it does when coming into hot surface contact.

Unfortunately Steam turbines have very little spin at plus 100* Celsius preffering a heat setting of plus 550 Celsius and above. At a heat setting of minus 10* Celsius it vey hard to get them to move at all.

Cheers Peter

Hello Posters,
My appologies in origination post I have only submitted the possitive action pump alone. The possitive action pump included in hydro turbine and how Carbon-CO2 is used to drive the system inclusive of heating and cooling but not the Carbon-CO2 heat to pressure.

Cheers Peter

Edited sorry posters site failure to upload image Carbon-Co2 heat pressure graph any help would be appreciated.Edited by DaS Energy 2012-01-05

Only if you use water as the working fluid.
Many fluids boil well below zero Celsius (at atmospheric pressure), and are great for such purposes as refrigeration and air conditioning, heat pumps and so on.

Something like propane is very low cost and readily available, and the boiling/condensing temperatures, and working pressures would make it practical for quite a few applications other than just combustion.

As long as you have a temperature differential, even a small one, you can get fluid to travel in a continuous loop and create a pressure differential.
And once you have a sustainable pressure differential, that can be converted to usable mechanical energy.

Cheers, �Tony.
