Making a Jig

I'm going to have to make a jig to get the hole centered in the bottom of the cans. Without a jig it's almost impossible. The hole has to be just right, perfectly centered.

Another very cool patent!!

Gordon thats sweet!!!!!!
Tried calling the inventor his number doesn't go thru??
Would love to talk to him and invite him here for a look see!

@Slovenia
Yes I understand centering is a pain to do ,Are you saying it will effect operation or its hard to sand when its off center?

Thanks

Centering hole in base of beer can

No, it effects the line up of the whole assembly. The holes in the frame have to be just right and if the hole in the can is off then the can will be setting right on the edge of the ring. To some degree we can adjust the ring from the side arm in and out, but the can is pretty much done if it's off center. If it's off center, you have to drill another hole in the frame assembly. You just don't have much play in that small ring.

My centering jig is taking to much time to mess with, so I'm going to have to do this another way.

Centering Hole

Well, centering the hole on the base of the can is no big deal after all. It does need to be centered on at least one side though but can be off on the other. Kind of like sighting in a scope. If it's off on both vertical and horizontal your screwed, but if you have it centered on vertical or horizontal, just turn the can till it's lined up with the ring connector hole on the mounting frame. This does need to be lined up so that you can get your ring adjusted right for the can. Now, connect your ring to the threaded rod mount and either adjust in or out until you're gap is equidistant all around the can.

Line:
Mark on one side of your can where the hole is centered with a fine magic marker. Have a center line drawn on the base of your frame lined up with a line drawn from your ring bracket hole down the back of the frame. These lines will help you get started right.

I have a lot of questions.
What container is suitable for boiling water ? I think it must be stainless steel but then : how do you plan to connect electrical terminals and got it without leaking hot water ?

I would like to use cheap aluminium pot but then will have a problem with terminals, because at least one of them need to be put into hole drilled in side wall which is no flat

Questions

Hi Boguslaw,
Your Questions:
1.) What container is suitable for boiling water ? I think it must be stainless steel but then.
Response:
Well, the inventor uses the aluminum beer can for his heater in Serbia and has done so for several years now according to him. According to him it works very well and there is no problem using the beer cans.

2.) How do you plan to connect electrical terminals and got it without leaking hot water?
Response:
The cup, beer can, is the positive electrode and the ring is the negative electrode. He has the cup, beer can horizontal within another container. The housing for the boiler has a water inlet and outlet. The outlet sends water to a heating radiator and a pump recirculates the water back to the heater and so on.

I guess it works very well. There are certain things I haven't asked him yet because I didn't want to frustrate him. I figured that once my boiler was finished he might share some more things with me.

3.) I would like to use cheap aluminium pot but then will have a problem with terminals, because at least one of them need to be put into hole drilled in side wall which is no flat :thinking
Response:
The hole for the beer can goes in the bottom of the beer can at dead center. There needs to be an insulator connected to the bottom of the beer can to help keep it at rigid as possible so it won't bump the negative cathode ring and short out the electrical.

P.S.: Thanks for sharing your thoughts!!

Best Regards,
Slovenia

Inward return at open end

Slovenia

The open and shows an Inner Ridge?
Is this the remains of the can end ?
Cut so as to leave an inner edge??

Thanks
Chet

[Slovenia]

Inner Edge

No, it's supposed to be straight. He does say to sand the edge from the outside putting a sort of bevel to it but, the way these cans are designed if cut straight across no thin material is going to be allowed to bevel inward past the perpendicular inside line of the can.

That was just a fast drawing he threw together for me.

See .... I liked the ridge!!

I was starting to like the ridge , Its called a "Choke" on a shot gun

Another way to Tune or compress the exiting energy..
Sigh ..... I was really liking the Choke!!

I have decided that the wolves can eat my shorts!! { the ones that want to take away my home ]
I am going to get up an extra hour early each day to spend that hour on this Device .

Your rig has some interesting adaptations that can be made,I am way to excited about this to not be doing something productive towards a replication!!
It will be a welcome distraction in my stressed out day!!

Besides I gotta Catch up to you "S"

Thanks Again
Chet

PS
Funny thing I was reading "Cores" thread [Peter Davey [gurugi]
And they were talking Cavitation,Of Course seeing what the little pistol shrimp does with his Tiny claw we know...... Yes Cavitation would be nice

Well one of My customers in NY is a boat yard.{This just dawned on me }
The IO mechanic had a Duoprop boat drive there that he said had gotten all deformed from "Heat".

A Duoprop is two propellers one spins opposite the other on the same shaft
Inline .very cool,, well actually I should say very Hot!!
Cavitation !!
Have you any idea how hard it is to heat something up that sits in the water?
Have you ever seen the vid of the balloon with water sitting directly on an open flame??

I think Mr C has a Cavitation event going on here??
Thats My Theory boguslaw....
But I am a much simpler man than you!!!

And tomorrow when I get home I'm gonna start my build!

I BELIEVE..........................

Finished Build

Hi Chet,

If everything goes well tomorrow, I should have a finished build to show you by COB. I got a lot done on it today. Some household chores have been cutting into this project and I'm sorry for that. The wife has seen me waste a lot of time and money on alternate fuel projects in the last ten years and she doesn't share my interest with alternate fuel. Anyway, I will try to have everything put together by tomorrow evening. I may still have to do some tuning on my cans, but everything else should be assembled by then hopefully.

I came up with some very simple jigs for doing a couple of things. If this pans out like I think it's going to, everyone will want to see my jigs because they make some processes a lot easier and more accurate. Accurate is the key here I think. Many have tried to do stuff and few have succeeded.

When you start your build, I'll share how I did my stuff if you want to know.

P.S.: If you can put a ridge on that baby feel free to try it. Listen to your gut, it doesn't lie. Few pay any attention to their gut because of so many other distractions everywhere.

Best Regards,
Slovenia

The real problem

S
Funny how you hit the nail on the head over here!!
Same problem .....My Wife! Well she's not a problem I'm crazy about her,
But she sees this work as a distraction .

I don't think we're alone either .

She came with me on this trip to NY and Tomorrow I'm Stopping in the Bronx to look for Russian beer cans
WHOOOO Boyyy............

Just a small note that may help with an idea if you need to get a wire through the can without touching the metal and yet withstand boiling water. I've got a water distiller and I can see the heating element in the boiling chamber which if fed power through a stainless steel wall. It appears there is a type of plastic for the feed through and one that obviously can withstand boiling water temperatures. I would guess a distiller manufacturer might be able to tell you what it is if you can't find it with Google.

Keep up the good work guys. Wish I had more time for this now.

Yeah,that's Im looking for, beer can is not a problem but I'd like to use SS kettle as outside water container with inlet/outlet as Slovenia explained. Thus arise problem with electrical connections, insulations and water proof. If that would be worked out and if I found it all workable I will move to adapt my old SS heavy 7L pot working with high pressure steam as a boiler for house. My perpetyal though is to effectively and cheaply heat my home ! That was my number one idea Ever !
Now I might find solution and it's this sonic boiler combined with nice Kapanadze electric generator with just tiny 2.5kW output.
2.5kW times 12 COP means I would get effectively around 30kW HEAT OUTPUT, while I need 16-20kW (that's what I use now , small coal burner 16kW).
Let's do it !

@ewizard
can you post any picture of this solution ?

Nice!!

Sounds great Boguslaw!!

Setbacks

Got in a hurry and had some setbacks. Still trying to meet my deadline for myself.
