$PLUG Was very busy today and didn't see the big news until now....I recall from Investor day about the AMZN trials..."we are looking at other opportunities with that same customer for other sites this year, which could increase that number. As far as the on-road vehicles, we're working on trials for a number of vehicles of different class types for that customer." Today's PR "This product expands Plug Power’s market reach into heavy-duty on and off-road applications that include Class 6, 7 and 8 trucks, transit buses and various port applications." The opportunities for the Heavy Duty ProGen are...HUGE!! Hold on...big things in '20!!
