Hi,
I did try to repeat alaskastar`s style of making hydrogen (as showed in video) with this results: I used slolution (cca 0,35 L) of sulphuric acid and destilled water in 1:1 proportion and bruteforce way

).
I tryed what I could obtain at this time: copper, lead, iron, stainless steel, galvanized iron, zinc, carbon, aluminium and (I hope) all of their combinations.
Some minor efect of bubling I recognized only with combination of zinc&iron. I also did some measurement (metals not shorted) and best combination seems to be aluminium&cupprum (over 1V).
I tryed also electrolysis with about 14V DC (not loaded) and got nothing better compared to my earlier tests with water&soda (titanium&SS cca 20amp 0,2L of Hydr./min. in one small cell)
So I was quiet disappointed.... in desperation a grabed a SS scourer lying aroud and what the heck! There was a strong reaction at last. Well pretty short but... It left solution with strange color, but it was continuing in minor bublig. I`ve got short video of that. If I could put it somewhere...
Any help is appreciated...
Has anyone some experience with that ?
sorry of my english...
