Anyone know anything about DARPA's PowerSwim?

A few years ago I remember a bunch of chatter about DARPA developing (or redeveloping) a device called PowerSwim that was based on the old Aqueon concept. It was supposed to be a kind of foil-based human powered DPV replacement for combat swimmers. There was all this talk about how great it was and they were going to rush it into production, but now I can't find any information on it that is less than 3 years old. I have sent DARPA a request to find out what happened to it, but have not heard anything back yet.

Does anyone out there know anything about what happened to PowerSwim?

Is any one else interested in lightweight PowerSwim style DPV alternatives to the heavy battery powered workhorses of industry standards?

a bit of info on Lunocet Monofin and PowerSwim here MONOFIN My guess is PowerSwim either worked so well that they made it secret, or it didn't work out so they lost interest. The Lunocet Monofin sounds interesting... a bit price-riskey however for something that's not main-stream and proven.

Thanks for the reply scraphound. I never did get a response form DARPA. The project appears to be closed and there is no longer a contact person listed to get any information. It seems to be all gone; vanished without a trace.

My impression: From this video, the DOL-Fin X-15 monofin system appears to function far superior to the videos I have seen of PowerSwim. In addition to appearing to be faster (from which we can assume it is also more efficient), the X-15 looks to be more compact, a lot more maneuverable and more practical to use.

What do you think?
