There were never any contracts, just letters of intent and vague things like that.
And the end game is the same, just instead of saying they will come up with a very specific product they are saying they will come up with a general technology that can be scaled and applied to a family of products, all of them pretty similar to what they were originally talking about anyway. And there was always talk about the technology being applied in a variety of fields, from the very start. So that hasn't changed in a bad way. Of course that's all theoretical because as of right now they don't seem to have anything, whether water heater or heat engine or whatever.
The problem isn't whether they have contracts or not, it isn't whether they call it a heater or an engine and it isn't whether they are involved in some investigation. The only problem is they haven't showed something that can heat water efficiently. No product.
