I have always agreed that the debt could be restructured with ~$3 to 5 million. I wrote about that close to a year ago and indeed agree, flat out, with your assessment. The problem is that it is so simple and logical that one would think it would have been done by now. Because that has not occurred, one has to question what is going on behind the scenes that would prevent it. Because if that could be done, the company should really take off and go forward. So one must ask "what is preventing WSTI from such an event or the other investment scenario in your post?".
The only thing that I can think of is the lack of sufficient sales during the current economic times (e.g along with oil price collapse, solar price collapse, solar company's bankruptcy, etc.) that keep sales down and profit margins low, just from all the competition. I think that would make a perspective investor a bit dubious to part with ~$5 million (+/-) or any large sum of money right now. But that is just my speculation. If there is something more sinister behind the scenes, I have no way of seeing it. With all of the really cool news items on this website posted by pmello3, one would think that things are just hunky-dory, and yet the company appears to be stagnant to us.
I really wish you would get someone to contact Bates and maybe even go over and touch him to see if he is breathing and has a pulse!
