One of the biggest hurdles we face with any large company is dealing with the safety of the technology, which is very misunderstood. They still have the impression we store hydrogen in a tank. We just have to educate them. They ask about the lines going from the unit to the engine, are they metal or plastic, what kind of wiring do we use, will the unit shut down if there is a problem, ect? All about liability and insurance company compliance. Almost like convincing sailors that they would not fall off the edge of the earth if they tried to reach the New World. Only a few in the beginning were willing to take a chance, and they went down in history. HLNT
