Finally i got some hours to do tests with my Geet baby.
Here are some of the findings:

12 inch rod: using petrol and petrol watermix
It runs. Rod got magnetic field and nice colors.
Savings on petrol around factor 2
Tried to use diesel and also used oil. Both didnt work.
Maybe i should have used the exhaust heat to warm the fuel, which i didnt.
Temp measured on the outertube: max. 220 degrees celcius

2 inch rod: using petrol and water.
It runs. Rod didnt color and small magnetic field.
Didnt measure consumption here.
Tried used oil and als diesel. Both didnt work.
Temp measured: around the outertube: max 300 degrees celcius

NON rod: using water and petrol. It runs good. On diesel and used oil it didnt.
Temp measured: around the outertube, same spot as always: Max. 360 degrees celcius.

Conclusion: rod length has impact on the outertube temperature.
Not sure if the rod is pulling the heat towards it self. The color marks on the tip of my long rod are blue..
It looks like my engine in comby with my geet runs better without the steel rods.

My goals are still not achieved. I wanted to run this powergenerator on an alternative fuel, like used oil and that didnt work.

More to come after some good nights of sleeping and thinking.

What Color is the Rod? Is it Blue? Is it Carbon Black? Is it Blue on one end, and not the other?  The Rod can tell you what is happening, "If you are a Black Smith."

Thanks for testing and sharing.   It takes a tremendous amount of time and patience, not to mention turtlebucks.

Then again, we all can contribute something to the cause.   

Keep the info coming

Thx Steve

Perhaps the geet has to be good and hot before switching over to diesel or oil.
Perhaps build a second bubbler so you can switch between fuels, with engine running, using taps/vaulves.

So as the rod length decreased the outer tube temp went up.
I think this is because less heat is being abzorbed by the inner tube.
Because the rod causes the gas molicules to speed up and collide with the tube surface more; absorbing more heat.
(Water absorbs heat better than almost anything else)

This restricion also means that the engine has to do more work sucking in the gas and may seem to run out of breath.
Work that gould be set to a usefull task.
When the rod was removed; the restriction was removed, which is why your genset was happiest.

I fear that your geet may just be pyrolysing/vapourising the fuel with very little Autothermal reformation going on.
The french are also using waste exhaust heat to pre boil the water before feeding it to  a geet.
I think this increases the amount of Steam Reformation that happens in the geet.

Another way of getting more heat into the intake gas, without the restriction is increasing surface area.
Finned, spiral, heat exchanger tube is available.
However; I would try a 'propeller' in stead of a rod to get the gass to spiral and thus to come into contact with the tube surface more.
You should see a small drop in outer tube temp if you try this.

Its possible that the geet was simply changing  your diatomic H2 to monatomic H+H which is why it ran on less H/2.
This in itself would be a valuble lesson:
You can use waste exhaust heat to get more out of your Hydrogen.  :)
Whats the metal catalyst for this again?

Hope that helps with your think Steve.

I tried that. I first make the geet as hot as i can with petrol, then i turn to oil or diesl. The issue is propably that i need to pre-heat the coil or diesel with an exhaust heater orso

I agree. It would make sense, but it is difficult to confirm this theory

option here is to make a geet reactor with a bigger innertube with rod. That way i will have a bigger opening for the full. But not sure if that is the way for the needed fuell acceleration......mucho questions.

I heard that a aluminium rod is an option when the reactor has a magnetic field. That way the rod can more easy rotate in the tube! Well, its worth to try.

Another way of getting more heat into the intake gas, without the restriction is increasing surface area.

I have a good idea with making a propellor of a coppertube, that should vortex the intake of the geet...

Its possible that the geet was simply changing  your diatomic H2 to monatomic H+H which is why it ran on less H/2.
This in itself would be a valuble lesson:

I used a steel rod, if thats what you mean? The fun was that i used in that test where i got that good result with less HHO, a bubler filled with water and used oil. The HHO went thru that bubler into the Geet. I need to redo that test and see what did the trick. 

Hope that helps with your think Steve.
Yes, it does, Logic. Thanks!

How do you keep the rod in the tube while allowing it to rotate Steve?

A rod idea:
Use a steel drill, with the unspiraled shank cut off, for a rod.
The spiral grooves will give swirl and less restriction.

Another idea for swirl:

Pleasure Steve  :)
I hope the drill idea works.
The turbulator should be easy to make by twisting a thin steel strip inside a tube.

I still want to know how you keep the rod in the tube while allowing it to rotate plz??

Are you bubbling exhaust through your bubbler?
I think it is important to heat the oil water mixture so that you get more vapour of both and less air.
Also the exhaust should be primarily CO2 and H2O.
The CO2 may be reduced to CO by hot carbon in the geet... ;)
