RE:As long a plasma torches put out NOXious fumes...What NOXious fumes are you talking about ? A plasma torch is not a combustion device. It does not produce NO2 as does an internal combustion engine or bunker C burner. Please clarify what you are referring to when you mention "health-affecting problems".
"Why spend millions on a problem when the current system is paid for...?" Obviously because you have a problem and the solution is available and will cost less than the current problem.
You are a basher for the sake of bashing.
