The only reason I have put so much hope into H2 is

The only reason I have put so much hope into H2 is that they have an actual plan, apparently funding and are supposedly definately using three engines. That means real world proof of working engines. That alone should jump the stick back to a decent point. From that point we will need one of the larger potential contracts to come through and or full scale production to meet them. It's the most realistic short term goal as those three engines can be produced in existing facility and interested parties can go visit them for some proof. That's my personal opinion on why H2 is so important right now. Plus it's a much easier in road than auto engines. I think he wasted years and years on that as it as his personal vision. The future of this tech is most likely industrial. China has a need for this. But I'm sure they want some action over here first. As would I.
