True enough. Perhaps the question should be phrased as "How much of the $230M that you are short is directly related to the decision to build a proprietary engine rather than buy an existing unit? Of that, how much is for engine development, and how much for plant renovation and additional equipment?"
above you mentioned being able to "discuss the message rationally" .... to do so it helps to ask rational questions that are based on fact .... look it up, its been released several times, that the cost of the entire project is anticipated to be around $230M .... they aren't $230M short .... regardless of the fact that your question isn't grounded in reality, it serves no useful purpose to ask it here .... as I've responded to some of your prior post, you need to ask the folks who know the answer to such questions .... continuing to do so here is beginning to appear as little more than a mud slinging exercise
