RE:clean-techYes, I also noticed that Bernard only mentioned 6N+. To me this showed a lot of faith in the technology, and made me even more excited about the near future! When (not if) the Purevap technology is shown to be able to produce that level of purity in one step, I have no doubt that the market will take notice; as will existing companies already producing 4 Nines and higher. I call a buy out at $3.00/share...In my opinion only. Thanks-Buda.
