I don't know if this has ever been posted at LENR forum before, I think it has not, and I think is impressive enough to share with our members. It was brought to my attention by Bob Greenyer, who has been recently offered one of the production HHO machines from Yull Brown's extinct company.
A company in South Korea produces and sells large scale industrial equipment that uses so called HHO or Brown's Gas technology for high end metal cutting and hazardous waste disposal. They present interesting videos of their installed machines performing impressive metal cuting tests of up to 800 mm thick steel plates.
The company site is not mobile friendly, and uses adobe flash heavily, but I think it's totally worth the look and having it on the radar. Judging for the images alone, and previously wathed videos of Yull Brown's assembly line in Australia, this South Korean company is using Brown's technology for producing the HHO from water.

The general specifications of their generators (they consume massive power!!!)

Of note is that they claim to have several of these installed in Japan.
