To piggyback on Tim in Vancouver's question.

Are you able to share with us some of the impediments the iron ore pelletization industry considers in adopting the torch technology other than cost?

Would it be fair to say these companies will be hesitant to adopt if the carbon tax vs torch adoption expense is marginal and just looked at as a cost of doing business. 

There is that component of banks making green technology a component to lending of course that may force their hand?

Am I correct in that the level of nitrogen oxide levels will also be a strong component as to whether or not to adopt?

Secondly, are you able to explain the minutiae of an actual torch maintenance routine preventative maintenance operation?

For example, is there a "swing torch" involved that would be utilized to change out the first torch needing new electrodes and then use that refurbished torch for the next torch in line needing refurbishment?

Or is it ok to have a torch off line for a time to replace the electrodes?

Thanks again for the opportunity presented here in this forum and all you and your team do to create a better world.
