Thanks AN, That is clearer. It is potentially all hope as far as I am concerned. There is no chance I am getting this thing for $3000. I do think when, and if it ever gets scaled down, then we can compare apples to apples. The inefficiencies of one off sites is going to drive the cost up for almost any technology, while panels are coming down. Also the maintenance issues with other technologies has to be considered. I will look at the videos when I have more time. I was looking at the websites you provided the last time this thread was up.
