as far as burning in lasers, the only limit is I have one knife switch which will be on a 60 amp or so breaker. Running two at a time might be a problem unless someone else brings another knife switch with tails to tie into panel. Running your laser straight for 8 hours would not burn off hardly any tube volts, it will clean up the gas a bit but it wont bring TV down in that short of a time. I have more garden hose than home depot, just make sure your fittings and connections are solid Site A is 5 minutes from home depot site b is 20 minutes.
I am terible at guessing distances but my best guess is...
Site A is an industrial space, vacant which has about a 30 x 100??? foot throw that is site A. Site A is not 100% yet Site b is a storage warehouse about 20 x 80 or so i dont know which has construction tools and crap stored in them. think of these places as just your basic 12 foot roll up door type places. My buddy has the keys to site a but not the owners approvial YET, site b is less desirable but slam dunk, we will know which one monday or tuesday. I have one other idea but it has low ceilings.
The hard part was finding three phase and water, that was the criteria. I mean hells bells...the cobra only needs 220v single phase at 40 amps and no water to make 50 watts










Both places have access to Broadband cable. site a easy, site b easier
