Peter as per this write up by Pyrogenesis, is there internal research by your team in the lab to come up with electrodes with a longer wear period? Without naming the composites, if you are working on this, are there any promising results? 

I suspect the changeout of the electrodes is a straightforward process so this next question is probably mundane but..  where there is a maintenance cost to this process, have adopters of this technology asked if you are trying to build a better mouse ( electrode ) trap thus decreasing the periodic changeout of the electrodes? 

I realize the start and stop of the torches are like night and day compared to deisel units but it's still a stranded cost to change out the electrodes.

Having said all this.. 1000 hours is nothing to sneeze at either and quite remarkable given the operating temperature of these things.

Thank you.
