I read it and watched the vids. Bunk. I can melt steel in the backyard fire pit with wood. Try it sometime it's not that hard, it stays hot for a long time, sometimes I can go back the next day and kick the ashes and get the hotspots started again sometimes. Other things I have melted. Beer cans, glass, a plastic rake, the bottom of my shoes, potato chip bags, an old playstation black promo disk from Pizza hut and army men.
