Solar water bubble PUMP

Solarstar

Watched a Bubble action pump today and was impressed as it works on the Geyser affect , no moving parts or electricity Pumping fluid for 500 tubes. Send me a private mail to see the video or more info   Paul

New Geyser Pumps

I recently installed a Sunnovations geyser pump. It was very simple, very versatile, and is working well.



Thus far, it's not compatible with evacuated tubes, but works with just about any harp-style flat plate collector.



We dissected it pretty well on this thread:

HMMmmmmm....

I am wondering if this would work with my proposed solid fuel burning appliance... The one thing that causes my sphincter to do the momba is the thought of having a roaring fire, and getting hit with a power outage. Think steam explosion potential. This might be the solution to that problem.



Gonna have to look deeper into the patent application and see if it could work.

Niles Movick had a patent...

He was from the peoples republic of Boulder. Will have to do some research... THe patent was something to do with moving fluid without a pump. I suspect a bubble pump was his concept.

Evacs and bubble pumps

Apparantly several Evac systems out there being pumped by these bubble pumps  but the one in the car wash is the only working system pump like this that I've seen ..scroll down at this link

Not a business plug for these guys as they do not make the geyser pump and are quite expensive , I'll stick with my PV powered pump.   Paul

Kingston ON install

Hey SolarStar,



Is this install in Kingston On?

Solarstar

Yes

Yes It is > Overall quite impressed with the system , of course with 500 tubes it generates alot, and hot water gets used alot with the consistancy of a continually used car wash, almost a perfect match to keep some of the system efficiencies in line with the required demand.   Paul

Lotsa patents for bubbles

The original "Geyser" pump was patented and trademarked by Eldon Haines and Bob Block from a company called Sunrise Research.

They manufactured the "Copper Cricket" for several years in Oregon.

The company folded but Eldon's patents are out there.



We were licensed for a while to manufacture them.

As Mark mentioned, Myles Movick made one and Wilfred Sorensen in Canada also makes one. Googling bubble pumps will get you a lot of hits.



One of the working features is the use of a vacuum to boil water at a lower temperature.

Mixing the water with alcohol (either ethyl or methyl) will help lower the boiling point and make it freeze tolerant.

The boiling water bubbles and lifts "slugs" of water in riser tubes to induce some flow in a closed loop.



We had mixed success with the design. At the time we licensed it, it was not quite ready for prime time.

I think it could lend itself to self pumping wood boilers, but the flow rates for solar are not really big.



It was fun, though! I still have the stuff we used to make the system work.



Of the three, I think the Sorensen design is the most viable, I am not sure about the energy cost (loss) associated with making the system self pump.
