Back in my high school years I had a portable cutting torch/welding setup that used (I think) a butane or propane cylinder and a pellet that you lit that poduced oxygen. You could heat up a piece of steel to cutting temp and then shut off the gas and use just the oxygen from the burning pellet to cut with.
I really have no desire to have another one, but it was pretty ingenious and I'd at least like to know the name.
