One has to look at this realistically. If a penny stock company can develop a hi tech PV cell on a shoe string budget, what keeps a very large PV company from throwing a lot of money at the problem and coming up with an equivalent PV cell or better.
I am a believer in SLTD and JN, but I am also a realist. This is why I put a lot of faith in JNs ability to acquire PV installers and grow the company in one of the hottest sectors in the US economy.
