Off the grid power for your phone (and other USB devices), just add water...brilliant!  However, from a quick search on the Internet, it seems it might only cost about $0.12 to charge a cellphone.  And, seeing that this unit will cost $229 or so, it might take some time to make up the cost.  I guess the real intention for this device is for hikers/explorers/no-man's-land-wanderers who will be away from a power source for a long time.  In that case, it would be a very useful device to have handy.
