Familiar only with what info about the specs are that are given online which corresponds with what MB2G had said.  So it's difficult to believe what the competition is saying, eh?  So the press release wording is questioned, no biggie. Perhaps that is Mr. Payne's way of saying, "start your engines," with the difference being that 500 units were bought from HydraGen...  somebody was impressed with the results to place that order, regardless of the surrounding hype, wording, or skepticism.
