Hi again Peter
My main profession is highway maintenance, I remember some time ago there was talk about PYR getting into the tunnelling bussiness with plasma tourches. Is there still any interest in this? Why I'm asking is because the methods right now to get services under the roadyway are terrible, boring is expensive and usually gets stuck somewhere along the line and you end up cutting up the asphalt anyway, but I can see where a plasma tourch if small enough would work better by "melting" a hole. That way not disturbing surrounding infrastructure. Kind of like a phaser in star trek ;)
Thanks Mike
