Just sent off another email to DARPA after a phone call. We'll see what comes from it. In the meantime, I will see what info I can pull together and summarize on things, points of contact, perhaps even put together a form letter.
I finally came across a clearer image of powerswim. It incorporates newer materials to be sure and slightly altered configuration but the primary concept and premise of operation are quite old as can be easily seen.
