With all due respect I beg to differ. In my opinion it "could" happen. Even IF FCEL had a market cap of $400M that's still peanuts... a small cap company. Right now they're only a micro cap stock.
The fuel cell industry will continue to grow as the years go by. FCEL may currently be strapped for cash, but technology-wise they're well positioned to capitalize on the market should they continue to secure funding.
