Perhaps there is a good reason no-one uses them? The demo looks good but they demo it in a test tube, why don't they demo it out in the open? Of course the gas puts out a match flame in a closed environment. If they claim it can save a turbine model, let them put up a video of it putting out a big flame from a pool of burning kero in an open environment. The fact that they haven't tells you all you need to know.
