Although it seems ironic, I=92ll probably have to follow the advice of Stupendous_Man and read my comics more skeptically. David Billington noted that an adjacent panel was suspect and indeed I found no connection between =93Theobald Wilson=94 and the discovery of acetylene. I did email Tim Hutchins (the engineer/author) to see if he could provide references for his claims, but have not received a response. I am sure that he=92s probably chortling at having fooled another idiot (myself) and he is probably mixing up new batches of fact and fiction for his strip. From reading the strip, I had the impression that the machine described moved a ram as the water in a cylinder froze and expanded. I did not think that they were describing =93explosive welding.=94 (I have seen a HERF (High Energy Rate Forming) machine in real life, but not while it was operating. It was at a company in Pittsburg and was
2-3 stories tall and went down through the floor (shock absorbers below). We saw a high speed video of an aluminum round being formed and you could see the shock waves as the aluminum deformed. Mostly they worked on refractory metals, but it was neat to see.)
What attracted me to the claims in the strip was that they seemed plausible and I=92ve provided some links I found from =93fact checking=94. (Those of you with better things to do should leave now and go do something useful.)
