There were numerous PR's released after public demonstrations of the beta units. At least one news paper article was written on one of the demonstrations. The units did what the company claimed they would do. The only down side was that Hydrogen was supplied by Gas vendors in large cylinders. That fuel cost many times what a reformer could produce Hydrogen for. Understand though, the company was demonstrating the operation of just the fuel cell. These beta units were not just built to prove that the system would work. They were made to test the system and maybe show possible areas that could be improved on before committing to the final production model.
