First of all, I own this stock, and have for 2 yrs ....no-one disputes the potential of this technology, but the biggest obstacle right now is getting funding for the run-off filters, etc. to be put in place. It all goes back to the weak economy , and the lack of money available by the various agencies interested in implementing this filtering system. "Hopefully" this will change, but as it stands right now, it's sort of a catch 22. I'm long on this, and will patiently wait for it to move up....in the mean time it's kind of interesting about the move it's made in the last 2 days , although I have not been able to find any news , anywhere to explain it.
