Ok I was looking for small stove for my work shop 16 X20 and very well insulated. I did not want to build a chimney so… I found this stove built by a guy on you tube known as Zero Fossil fuel. He is into Bedini / Tesla  stuff. This was several months back and I liked its simplicity. I will complete this stove pretty much as drawn so I have my heater. I will then look forward to a second light weight higher efficiency build.
go to alt-nrg.org/index.shtml


I will post more soon  Thanks

I guess in seven days :(

The round stove on the left hand side of this video is extremely efficente and simple to build. This stove that I describe was first suggested by Pekka, you can see his videos as well.

I understand about the expense. I have been lucky so far My major expense on steel was the outer tank. A used piece of 12 inch well casing 1/4 thick wall 4 feet long . This had a 1/4 inch thick tar and paper coating on the entire out side I had to remove. $46.00 and 18.00 for a piece of 3/8 round stock & 1inch by 1/8 9 feet of mild steel. I also have 36.00 in fire brick. Well off to do more work on her. I hope to do a test burn today. Once that is done I should be close to finishing

4 DAYS UNTIL I CAN POST PICTURES!!!!!!!

Well I scrounged and I bought, I built and I thought. I did all I could to fallow a plan



I gotta say it took far longer than I ever dreamed to get to here. I have enjoyed the build to this point.


I was disappointed with the first burn. I think I know what I did wrong and I hope to have time this weekend to change it.





Ok my theory! I had poor draw until I got the stove a little warm. Then she was drawing good until she got real warm. The flu never got warm.

I think I have to little clearance between the top of my j tube and the outer tank ,about 1 3/4 inch


More  to come

You are very precise in your constructions. First I agree with you, just give a bit more space between the top of the riser tube and the top of the heat exchanger.

Second, in the second video, did you make the fire test with a chimney? can you show us details of the chimney? does it go straight up or is it horizontal? where is the chimney exit located in relation to the combustion chamber? With a straight up vertical chimney, there is a sweet spot where you restrict the primary air and at the same time you have enough air for combustion. This way, you have immediate draw from the chimney and no smoke or fire comes out through the fuel loading door.

Thanks for the kind words and the reply. This video is not the best but will show you the chimney. I have it apart and will get a better vid later along with some dimensions . I want to learn about this Sweet spot.
I am looking forward to you ideas and truly appreciate any and all responses.

Did you fire the stove outdoors? does it smoke outdoors the same way it smokes indoors?

It seems to me that your building is very well insulated. Sooner or later you will have to add outside air to the stove.

Ok I opened up my clearance in the top and it helped but the stove is still non functional at this point. So…  caotropheus  mentioned a sweet spot. I remembered that my tank was about 11 inches taller than Zero’s. My exhaust flu temp. is way to cool, his exhaust is behind the J tube though a bit off center. This would be much warmer air. I have mine a good 8 to 10 inches lower than the J tube. MUCH COOLER air … Hum…
I wonder?  



NOW where to relocate the exhaust too......?

Yes, you gain in heat transfer from the stove to the environment, exhaust is cooler, but draft is lousy. I would place the chimney exit just above the combustion chamber

I headed out back and recut my exhaust slightly lower than the burn chamber. The bottom of my 4 inch pipe is about 1/2 lower. I did this before I read caotropheus response. I agree with him and may move it up but... WoW what a difference. The big issue now is I wish I had not opened up the top of the J tube to the tank. The top of the stove is not getting as hot as I want it. :x  I am burning far hotter and have good draft. I will cut a 6 inch steel box tube spacer and play with fine tuning that. The good thing is I am getting a good understanding of how it works. I also feel good that I will be able to actually use the stove. I will get pictures and video soon. I want to dial it in and the explain what I did. Thanks again
