    This is outrageous stuff. I wish you as much success as you can take! We need it. In Germany and Sweden, companies use elektrolytic hydrogen to replace coal, but then you have the efficiency problems with electrolyzers and as I hear, making steel with hydrogen is not simple. This seems to be way more elegant and energy saving.

    Not what i was searching for but that was pretty cool! I studied 2.5 years to become a welder and we learn quite a bit about some of this. Welding is basically a very small process like this of taking the electrodes and either making the courant go through the electrode so that the electrode melts or to make an electric arc from a tungsten electrode that melts a third metal part into the piece. So this method shown here is basically the second way of welding wich makes an arc between two electrodes the apply energy to what's in the middle and melt it.

    Why are there 2 thumbs down to this vid (as at 30 Jan 2021)? Who the blazes wouldn't like this idea?

    Elon said last week he needs a LOT of 99.8 % nickel to make his batteries, Don says his process produces a better grade of metal, ding! a market for this process if it can produce pure enough metal

    Can do anything with clean cheap energy.
    Solar power in the long dry season, Candu in the big wet, and North Australia is the third biggest industrial location, the world needs now.

    It sounds like not very much has been holding back this technology other than the discovery of that special metal alloy (iron-chromium) for the anode. I always wondered why the production method for aluminium wasn't more widespread; with smaller scale electrolytic furnaces perhaps its time has come, and just in time 😊

    Why not convert New Zealand's unwanted decomissioned Tiwai Point Aluminium smelter to producing steel from Taranaki iron sands instead of uneconomic Aluminium subsidised with cheap electricity...?

    Very interesting
