Startup Idea : Portable Supercomputer

Used first, second and third generation iPhones all have a few things in common. First, they all have processors that are superior to anything built pre-2003. Second, they share a wifi connection. Third, they are being disposed of as useless and can be picked up for almost nothing. Finally, they can all be jailbroken to run a version of linux with any kind of small application cluster. What if you could take a hundred of these old phones, outfit them with a version of linux that supports a distributed computing platform, and then daisychain them all to a power/USB cable (yes, power them all over USB). Connect them all to a Raspberry Pi, Arduino or gadgeteer controller and then run distributed computing applications that used wifi or blue tooth as a local communications layer. New nodes would be as easy to add as carrying another suitcase of these phones into a room with an existing cluster. Best of all, because they all have their own batteries, the cluster could operate for short periods of time (hours) in environments that have inconsistent or unsustained power grids.
