Hello Peter, this iron ore opportunity is tremendous but it is an application in which the torches just happen to be able to be retrofitted to furnaces that were designed for the current burners. I can't help but wonder if a furnace with plasma torches encorporated in the design as the heat source would be more efficient. There are plenty of active furnaces that you can retrofit but is there an opportunity to partner with these large companies to design a new furnace with the plasma torches as part of the design and do you see substantial benefits in doing this? Is there an opportunity to design new plants for iron ore, steel, cement etc., or are you looking at just replacing the current burners with plasma torches?
