Fluidyne water pump

nice but that looks extremely inefficient. I would think there are many better ways to do solar work. sterling engine or photovoltaics for instance

doubt it.

[RCFLYER83]

Kinda like a coffee maker?

[pyrobryan]

Thermal syphoning?

[1crazyfocker]

Question is there any check valves in that? and if so where are some plans for it?

[steveBB30]

Guessing the black cylinders contain check valves, arranged to allow upwards flow. Expect they'd have to have fairly low lifing pressures.

my Mr coffee does this a lot easier....AND I get to drink the coffee! now thinking of a solar coffee maker !!! but when its that hot do you REALLY want to drink coffee? maybe the coffee grounds can be the fuel source? boiled hot water in the garden to cook the plants. lovely. but then no coffee.What a waste of time!

[rompeortosss]

to much energy needs that to work

[may9119]

1% efficience..

[docsharp00]

yes but if you put it in your garden, with a parabolic mirror instead of the 'lighter' it's 100% free pumping :)

[bombsawayd]

this is how they built the pyramids

[prototype9000]

what are you using for the valve

[douro20]

It heats and pumps water at the same time. Such technologies have been explored for use in third world countries.

[RockManAU]

Would there be enough heat if you put it at the focal point of a reflective parabolic dish in the sun I wonder?

[Tarzbloke]

Ingenious application of the air elasticity principle that is behind Stirling engines.

Bookmarked and 5 star for sure :-)

[Jims99ZR2]

Weak stream? Enlarged prostate? You might need FlowMax!

Kinda neat!

[secret00agent00man]

that sounds like a truck exhaust part brand!

[Weltar]

i would use a bucket...

[gotalentguy]

Do you sell plans with dimensions to make the setup where you had the one cup on the floor and the other cup way up on the table?

[gilbondfac]

no plans for the moment ...but come soon!

please wait ! thanks !

[DeepGlue555]

i think this is a similar idea to the percolator in your coffee maker

[gilbondfac]

no it's thermodynamic cycle like stirling motor

[electrique527]

Oh, BTW ...

how do you start the engine? Or is it self starting?

Richard

[electrique527]

Hi!

Lovely, well done! Did you determine the dimensions and volumes by calculation or trial and error?

Can you give some dimensions of this pump / engine?

Thank you, good luck!

Richard

[RyuDarragh]

Isn't this the same process as the "percolator" coffee pot as a general principle?

[areenarena]

cool but not effectif.

[overunitydotcom]

Great pump Charles !

Please come to

overunityDOTcom and present your device there

with more infos.

( Please substitute the DOT with a real . )

Many thanks in advance.

Regards,Stefan.

I am curious. Could the same pump action be performed at a much lower temperature using a different fluid than water? I am trying to think of ways to make waste heat more productive, but most waste heat doesnt get to the boiling point of water.

[FckTheFreeWorld]

Im confused

[OgreOwner]

As the water in the right hand side oscillates, it produces pressure changes in the pump section on the left. No percolation of the pumped fluid is going on. The pump section is two check valves that allow it to suck in water on a low pressure spike, then push water out the top on a high pressure spike. This little pump is drawing water from what looks to me to be about 1 meter below the outlet. If the sun could produce the heat of that blowtorch, it could water some plants outside. Nice!

[gilbondfac]

cool!! congratulation you've understand

very well!

[wwwSumatechUSAdotcom]

Is the water percolating or is there some mechanical means of pumping going on? Thanks

[OgreOwner]

The water being pumped is pulled from the containers on the left side and is drawn up by the changing pressures in the fluidyne stirling engine on the right hand side of the apparatus. The heat being applied is a lot hotter than it is easy to get with solar. If you are interested in this engine, you should go to your local University library and look for 2 books by C.D. West "Principles and Applications of Stirling Engines" and "Liquid Piston Stirling Engines." Or just search the web!

[m3sca1]

wow thats cool-does the water being pumped heat up or does the heat stay on the hot side?

[OgreOwner]

All the heat stays on the right side.
