As far as I am concerned, Rossi walked away from trillions when he abandoned the 1MW with the Big Frankies. I know that one move on his part has been swept under the rug, but it does lay to waste the argument Rossi has something. Last Paradigmnoia checked, the discarded shells on those plants were in the parking lot of the Doral warehouse.
After that, my guess is that Dewey or Darden are not worried at all about any lost investment opportunity.
