Thank you kindly Bernard for your quick reply.  Yes it makes total sense now.  It's a very common oversight with my French speaking colleagues..when they mean to say 20%.they often say 1/20.  

But good to clarify 1/5 which kinda makes sense.  I do feel that purevap scaling silicon nano-powders could be much bigger than 1/5 of PyroGenesis....it could in essence blowup to 1/3-1/2 if we really disrupt the EV battery market replacing graphite component with silicon nano-powders made by purevap!!!
