I would add that tunneling is another distinct area that has the potential of a significant revenue stream. And that what we know that PYR is already involved with.

As for the plasma technology, it has tons of other potential applications, that could be explored and pursued by PYR when having enough resources and/or interest to go those directions:

CLEAN Waste Destruction; Enter the steel and cement industries and reduce all greenhouse gases they produce. This latter one has enormous potential, the 2 industries account for a third of global greenhouse gas emissions !!!
