Summer's.....
« on April 21st, 2015, 09:00 AM »
....coming up, so I thought I'd do something fun with an old lawn mower, just because.
I was thinking trying out a GEET bubbler, much like what Firepinto did, just to see what gives.
Can't seem to be able to find any open documents on the matter though showing the how to bits, does anyone have something they feel like sharing......?

Otherwise if your build is open source FP, feel free to show me what you did.
I feel like doing just a little something to pee off the fossile fuel companies, that's always a hoot and a holler :hide: :-D

search GEET.

there is also a lot of things like getting the rod polarity correct and length right ECT.

ull need to do some home work before you jump in. there are some  things that need to be done correctly...  to get the reactor to work any way...  as far as the vapor part... i think here are Manny things that can be done on that end... ultrasonic transducers ECT.

Well, thank you kindly Sir :-D

I figured I'll just start with the bubbler, having the exhaust recycled through the bubbler, vaporizing the gasoline, feed it back to the intake manifold, mix it with air and plain just feed that mix to the motor, to start with anyway.
If I can cut gas mileage, or gas lawn acres more like it, then that would suit me just fine :-)

Hi Lynx, I don't know if you saw my post in reply about a geet question, but here it is:
kenssurplus post about his geet reactor experiments
Quote
Many years ago, I built a geet reactor for use on a ~6.6 KW genset.  In my testing and observations, these are my experiences with it.
Now admittedly, I quit following the progress of the development team and the various versions and the like soon after the inventor took his ball and left the playground. 

To answer your questions based upon my experiences,
1)  It does actually work.  However, I don't know what advertisements you are referring to.  I found that I could run my gasoline genset from a geet reactor and bubbler with just a little gas and lots of other stuff in the bubbler.  It wasn't foolproof, needed babysitting constantly, and could not respond to varying loads without manual adjustment.

2)I'm not sure.  I didn't use an injector, just a bubbler filled with stuff to burn, so perhaps you are referring to a variation I am not familiar with.

3)The hot exhaust gasses pass around the outside of the intake tube (if I am recalling the config correctly) and preheat the fuel /air mixture thats in the inside intake tube. Inside the intake tube is the steel rod which gets at least red hot, hot enough to crack the heavy hydrocarbons to a smaller hydrogen or at least a smaller hydrocarbon.  I guess I am not sure about your question.

4)The steel rod in some variants is stationary with weld bumps holding it in a snug fit position inside the intake tube (my version).  in other versions, the tube is free to rotate and spins up to a high speed rotation with the incomming air vortexing around it at mach number speeds.  The length of the rod is determined by the type of fuel you are trying to crack.  light fuels, require a different length than heavy crude etc.

5)My steel rod is a stainless steel print head guide rod from an old dot matrix printer.  See above answers about what it does.  I have no idea if there is anything better. If you have the money, why not try a platinum rod? That should be awesome as a catalytic cracker.

6)I would venture a leap of logic that HHO would be a better solution. I always had to be adjusting the air/fuel ratio by opening and closing valves.  The fuel in the bubbler first vaporizes the lighter fuel fractions first, and then the heavier ones after, so for modern fuels that are a mix of many fractions and gunk, that means always adjusting for a changing fuel type as you are running.  For a scooter, this sounds nightmarish, because you are then adding in varying loads to the motor which needs to be adjusted for not only the new change in load / rpm / but fuel / air mixture.

Good luck with your project though, I don't want to squash anyone's motivation to do something.

Oh, one other thing I should mention.  The geet reactor runs best with the motor starving for air ( in other words operating at a higher vacuum than normal).  You can tell when your vacuum is getting close as the engine will nearly turn over just by flicking it with your finger (very easy to crank).  The vacuum is regulated by the air intake valve, the fuel valve, the exhaust diversion valve, and I think one more valve somewhere. :)
I used a plastic 5 gallon bucket with a plastic lid (an old motor oil pail) for the bubbler.  I inititally had difficulty maintaining the seals from my copper tubing entering and exiting the bubbler.  Then, when I did achieve good seals, the plastic was not strong enough to withstand the vacuum placed upon it by the generator and it collapsed in like a raisin.  So, use a bubbler container that has some good strength to it as well as limiting how much surface area it has to crush itself.

Also check out firepinto's reply after mine in that thread.  He ran a push lawnmower with a geet device for a season.  Very good info from him.
If you would like pics of my setup, it is still attached to the generator, but I have not touched it for several years.  I might could take some quick snaps of it if you beg nicely.
:D

Thanks Ken, appreciate it :thumbsup:
By the looks of it my first goal should be to just try to run the lawnmower on the bubbler using the exhaust to preheat the (recycled) gas, if I get that far I'd be most happy, then I could start comparing gas consumption between the two (original - bubbler).

I basically built mine like the original plans that were on the net over 10 years ago.  It was just a simple drawing.  My rod had 3 welded nubs on each end to keep it centered in the pipe.  I seem to remember someone replacing the welds with ceramic beads at one time.  I know I had made a video of the mower running, but I have no idea if I still have any video.  It was all recorded on a digital tape camcorder.  There is a cameo of the mower in my lost HHO tapes at 2:07 in this video:


https://www.youtube.com/watch?v=QnN3hXWvTHk#

It has it's bubbler removed, because I was working on adapting a small carburator  from a chain saw to replace it.  That never worked out, and I started working on HHO instead.  The bubbler was made out of a water filter like this one:

It eventually stress cracked and broke at the threads.  The O ring stretches from all the gasoline too.  I should go through all my old digital tapes to see what I still have. :P

Ha!  I found a clip of the mower running with a gasoline and water mix in the tank.  The problem is it is on digital tape and I need a PC with firewire to get it here.  That might take some rigging with my junk computer collection. :P

I have the video rendered in HD.  I'm going to upload it tomorrow somewhere that has much faster internet. :)  One of my old salvaged CCTV DVR computers with Kubuntu loaded on it had firewire ports.  With some heavy use of virtual digital duct tape, I got Kdenlive to pull the video off the DV tape.  :dodgy:  It turned out real nice though. :D

Now I just feel real old watching the clip.

The carb was added much later.  I believe this video was taken soon after I completed building it.  I also added a sight glass to the right side of the reactor to try and view plasma balls.  I think I added a 4 way fitting or something, and then took a threaded PVC adapter and glued a round piece of plexiglass into it.  It started with out any extra help if you felt like pulling the cord a lot.  I had a spray bottle with some gasoline in it that I sprayed in a valve opening sometimes.

Very nice work F.P.  Way better than my poor attempts.  Of course, if I new it was going to go prime-time t.v., then I would have  spruced mine up a bit.


I made a exhaust flange to mount to the existing muffler flange to route hot exhaust into the geet reactor.



I used flexible exhaust pipe to connect the reactor to my homebuilt exhaust flange.


 In these pics, my bubbler is missing, and also the exhaust bypasstube to the bubbler is gone (but the connector is still there).

Compiled a set of selected images from your clip FP, just for reference.
Am I mistaken in seeing 3 ports/tubes attached to the motor, 1 thin tube (hose really) on one side and 2 larger tubes attached on the other side, a black tube over a white.......?

I'm thinking there's only need for 2 ports, one for the inlet and one for the exhaust, if I'm not altogether mistaken here of course.

I thought I should show you what the rod looks like:

Here it is in front of the port it goes into. it is 12 inches long  This stainless steel rod is rounded  blunt for about 1/4 to 1/2 inch at the tip where the intake gasses first hit it.



There is bluing that starts from between 2 1/2 inches to 4 inches  from the rounded tip (varies as you turn the rod) to the end of the rod, showing that that is where the heat began to alter the temper of the stainless steel rod.



This bluing starts about where my thumb is.  I probably should have had a shorter rod according to the instructions, but hey, I do my own thing.

Lynx, the small tube F.P. showed in his vid is likely the crankcase vent extended and routed into the intake.  I seem to remember some talk of such things way back.  I didn't do that on mine though.

Also, I found my rod had been sucked all the way into the outlet tee of the reactor that then goes into the engine air / fuel intake.  With my rod all the way against the tee, it may have had an erroneous heat blueing mark, so take it with whatever grains you want.
:blush:

Yeah the small clear tube is the crankcase vent.   I think that engine had weak piston rings, and closed loop experiments probably didn't help them out.  You can see plenty of oil film trying to make it's way through that small clear tube.  The black hose goes into the intake manifold.  I had to do some modifications to the engine because originally the intake was on the other side of the engine.  I flipped the manifold around and rigged it in place with some cobbling.  It was a steel tube with an aluminum flange on the block side if I remember right.  I believe I silver soldered a plumbing fitting to that steel tube.  Those memories are getting foggy. :P

The biggest thing I think should be thought about in the design of these things is full atomisation of ALL of the fuel in the tank.  I had huge problems with the "gunk" in gasoline being left over.  It would not run on that stuff.  The tricks of mixing water and waste oil in the fuel really don't do much.  Some steam might make its way into the manifold to give a steam engine effect, but I think waste oil will not atomize in a bubbler system.   That was part of the reason I wanted to try a tiny carburator.  An injector would probably work the best if it was sprayed directly on to the hot end of the rod in the reactor.  I kind of think most injectors will have way too much flow for a small system like these.

I just remembered another change I did.  The red PEX tube leading from the muffler side of the reactor to the blue bubbler ended up melting.  I replaced it with some flexible copper tubing.  I think I used compression fittings.
