Hello Peter, I have a couple of questions. In this latest release you refer to the "opportunities" of the Purevap process as "nothing short of intoxicating". I'm not sure if I am reading too much into this but I noticed you said Purevap and not Purevap QRR so my question is are you working on other applications of the Purevap not related to quartz reduction? My other question is about molten silicon for energy storage which seems to be getting some attention lately and is considered to be a viable technology for energy storage. Can you tell us if you are looking into molten silicon as another project and do you know if plasma torches could be used effectively in this process? Thank You.
