Hi Gary,
That is a very powerful version he was using.
The torches you can buy from Eagle Research of course uses a lot less and produces less.
Interesting you can melt tungsten like butter but the flame won't burn your hand.

Melt a rock into a puddle and when it hardens like a moonstone with hardness of 9..diamond is 10. Lots of other applications.
I saw that video clip you posted. Was on the news. Not sure how he can get a patent, George Weiseman already put the info in public domain and Yull Brown had a patent on the concept and Rhoads (William??) had a similar one. Anything in public domain is not patentable. He may have independently discovered it and was unaware it already existed.
Patents are good for 17 years I believe and Rhoads and Brown's expired. The exact method that guy in the video is using is basically what you can buy off the shelf at Eagle Research...or build your own.
