Probably this time next year. PLUG will be in huge demand. Huge untapped market. Airports. Refrigerated truck cargo. Forklifts. City State and Federal gov't contract. And if hydrogen cars take off plug will be there producing the infrastructure. You couple all this with the technology to produce H2 cheaply from H2O, IMHO PLUG will be bigger than Exxon. Don't doubt me! $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$
