OK, that figures, I thought of butane, propane. There is talk now that we can manage without russian gas for one year in Europe, how is this, do we have large stored amount of gas? Also US are going to ship gas to us, but thats smaller amounts?
For long time ago we used gasified carbon, "stadsgas" in swedish homes but stopped because of CO-danger, also we got electricity. It was a "popular" way of commiting suicide, putting you head into a owen and turn on the gas. As I understand, this is a good way to die, non-painfull? I think submarines carry a canister of compressed CO-gas that can be used for suicide if the boat sinks and can not be rescued.
