Up-cycle, recycle, reuse

That's for sure...there are some horror stories about people trying to make things out of these sort of tanks. I was told about one guy (I assume the person who told me was telling the truth, but I don't know enough about this sort of stuff) a few years ago a young bloke was trying to make a heater (for his shed) out of an old tank and the minute he hit it with an angle grinder...BOOM....his wife heard the explosion and called the paramedics....apparently (so I'm told) they had to pick bits of the guy off the rafters in his shed...yuk....I'm told the poor bugger left a wife and 4 kids. So, dumb question or not, I'm going to ask if I don't know - regardless of the topic.
