What you forgot to mention is that that $1 Billion estimate was from the Pellingrino Report which very explicitly stated that it was based on a number of ASSUMPTIONS, including that it worked (which has yet to be proven)
that it is economic to produce (which does not necessarily follow from 3rd party validation).
RE: "No shady transactions!" Many Opel investors would strongly disagree with that.
For example the time Opel issued a PR carefully worded to give the impression a milestone had been achieved without explicitly saying so. Many investors asked for clarification from Opel: was this, or was it not, a milestone. Opel refused to say. Later it became evident that it was NOT a milestone. I'd call that pretty shady.
