I can read most of it. It uses ultra capacitors and the tether cord is a pull string to a generator to charge it up. So you pull the cord to run the generator and charge up the capacitors. The guy in the lower left photo holding it extended is actually charging it. The pull cord is tethered to his back pack so by extending his arm out he's running the generator to chuge the "ultra" capacitor which accoding to this wonderful product sheet, only takes a few strokes to reach a "useful charge".
Its supposedly made of polycarbonate and has a pyrex window. Supposed to be totally sealed to the outside world. I don't think its real, I think some one should try and email Adam Scott Hammerman at gmail.com and see what happens.
I am sure it will sell for $395.95 and should be listed as being available in June (what year we may never know for sure).
