I did run into a polish guy who attempted to make one... but it was online and had to be translated by google. I don't know that he ever got it to work as dotto claimed.
On my workbench I have a 4inch wide by 1/4inch thick by 36 inches long piece of solid copper bar. On one end I put peltiers with cold side facing the copper and on the other I put peltiers with hot side facing the copper. When I power it up, I get about 150degree F disparity over that 36inch length. It results in about 40-50mV of potential becoming measurable using a voltmeter lead on both ends of the copper bar. This showed me I need a better method to heat the Hot end. I am looking at inductive heating type circuits to replace the hot side peltiers. Looking for closer to 500-600degree F disparity to be realized between the two ends.
I then have a 12inch long by 1/2inch diameter rod of monel alloy that will be used to bridge the hot and cold ends of the copper bar along with some lumps of silicon to be put on one side of the monel in the junction where it meets the copper to help with the unidirectionality of the flow.
A big problem here is dottos sized copper ring was 1/2inch thick, by 9 inches Tall by 96inches long or so... and I can't find anyone that sells copper in that size. Best I could find was 3inch wide, 1/4inch thick, 96 inches long. And that was still 500 USD. I'd need 6 of those if I wanted to make a composite that matched the sizing dotto noted. (which is what the polish guy did.) Given inflation I don't have the funds to pay for such even if it was available.
I don't know how you will get that done. I'm not interested in collaborating. People always take advantage and never carry their end. I'm good doing this stuff alone. Best of luck to you tho!
People always say that when they make Zero effort on their own hoping the one that Did the work will give it away. I am not that person and being Selfish in this case is your opinion levied as an angle to guilt me into sharing. No thanks. Best of luck!

Hahaha... another clown who thinks he knows best. Fuck off wonder muffin.
