Oh it's not a new way at all.  I'm up here in the north east USA where it
gets cold in the winter.  When water pipes were steel or copper, we used to
thaw frozen pipes that way.  Just hook on with a welder and let the juice
heat the pipe until it thawed the ice inside.  You had to watch the welder
so you didn't cook it though. A copper or steel pipe doesn't have much
resistance.  It's a heavy draw on the welder but being careful, it works.
