Despite appearances, this is a mobile phone and not a satellite phone. Maybe I should say it's a mobile phone with satellite pretensions. Whatever, it's the latest concept phone from Japanese company KDDI, and despite its ability to operate without a battery, it's clearly not going to go on sale any time soon (at least,not in the UK, where our five days of sunshine a year would render it less than useless!)

KDDI also had several other odd-looking concept phones on display at this year's CEATEC 2008 event, which you can see after the jump.
