How? One day you walk into a welding store or a... Hey can you mix up some hydrogen and oxygen/helium gas for me. I have my tech diver card. I struggle to get pure O2 sometimes in my area. I'm a doctor and a tech diver. lol. thanks for the video, very interesting.
As a swede myself I´m a bit curious about the group of hydrogen divers you are talking about. I can´t really make out the names you were talking about, but I think one of them is Åke Larsson? According to his profile in a swedis divers forum it seems to be the guy you mentioned. But the woman? In all honesty the pronounciation isn´t really spot on 🙂, (swedish is a difficult language, so I´m not complaining) so to say, but I think you say that the surname is Lind? But can you please type her first name? And if you have the name of the group that would be awesome too. 🙂Thanks for a great video!
