Actually I doMelida asks: "Do you have any idea what plasma torches are capable of doing? "
The short answer is yes I do.
Nowadays was using plasma blasters in underground mining as early as 1982.
They could blast a hole the size of a minivan in a rockface without having to deal with the noxious fumes associated with using dynamite.
I've seen them in action.
Why do you ask Melida?
