RSI Silicon: Solar Grade Silicon Reprise
There has been a dearth of news regarding RSI Silicon Products, LLC since RSI Silicon: Solar Grade Silicon from Pennsylvania (then Alabama) explained the RSI Silicon process. In fact, I missed an earlier article by Solarbuzz titled “RSI Silicon Products Nears Completion of Solar Grade Silicon Manufacturing Plant” from January 18, 2008, that has now been removed from their website. Google’s cache snapshot is here for as long as it lasts. Towards the end of the article, Solarbuzz said:
The major equipment items have been delivered to the 178,000 square foot Easton facility
RSI Silicon: Solar Grade Silicon from Pennsylvania (then Alabama)
Novel process begins with a Sodium Silicate (Na2SiO3) precursor in solution.
The complete production process patent has been published by WIPO.
RSI Silicon claims Solar Grade Silicon production will start in Q2 2008 with 1000 metric ton annual capacity.
RSI (Reaction Sciences, Inc.) Silicon is commercializing a process for six nines (6N) or 99.9999+% pure solar grade silicon that does not require metallurgical silicon (mg-Si) as in an input. Proven polysilicon and solar grade silicon production processes all share metallurgical silicon as a feedstock including the Siemens, Fluidized Bed Reactor, and upgraded metallurgical processes.
After noticing a recent increase in traffic and interest regarding Easton, Pennsylvania USA, based RSI Silicon, I redoubled my efforts to research and establish a dialog with the

Cool Earth SolarCool Earth Solar (CES, http://www.coolearthsolar.com) has revamped their website and is reshaping solar energy. I heard from CEO Rob Lamkin that CES Senior Team member, Dr. Aurelius Prochazka, co-author of RailsSpace: Building a Social Networking Website with Ruby on Rails, was involved with the implementation. Back on August 24, 2007, the press release, COOL EARTH SOLAR FILES PATENTS FOR SOLAR TECHNOLOGY, demonstrates CSE efforts to protect their Intellectual Property (IP). And Cool Earth Solar in the News was nice enough to link to my
