Seeing as My glass is half Full, I believe you said the same thing about CLNE's Management. (They turned a Very Nice Quarter), they seem to be managing when they need to.
It seems to be, a lack of patience to allow these Companies to get going, Nobody likes change, but it happens and sometimes many are Left Behind. Well there is no dought for Me, this one is well on it's way, even with the falling price in Oil the past 2 years CLNE has made better Numbers and NOW Oil is up, and Many states along with the Fed are pushing for change.
CMI has a good article on the Available Near Zero Engine from CMI/WPRT. Lets Remember, if it was so easy to start and run a business, we would all do it and no-body would work for someone else. When it is Time to Make a tough Decision can Management do it or not? Well we are at that Cross-road.
If this was happening in the 70's, Big oil would have buried this Tech. Today you can't bury it, but you can still make it Hard and that is another Hurdle to jump.... Good Day.
