IMO the real challenge to Ecosphere comes in the form of petrofracking, and the big name here is the Canadian company, GasFrac Energy Services. The stock has been on a tear in the last two days. As soon as I learned of this technology and company, I bought into GSFVF and am up 40% in a week. I'm keeping my ESPH shares (bought at .68 in March of 2010) and hoping for another good run, at which point I will be real tempted to get out of ESPH, and let my money ride on GSFVF, which looks like a surer bet in the long run for this investment niche. I encourage you all to check out the company: www.gasfrac.com
