When you're already tracking every kid out there to make sure no one gets into too much mischief, you definitely need a way to make a call whilst in "mountainous areas or at sea," right? Apparently the Japanese government thinks so, as it's planning on bringing satellite calling to the masses by launching a bird that's 50-meters in diameter in order to enable "ordinary handsets" (you know, the ones without the mile-long antennas) to make satellite calls in times of emergency with just slight modifications. The aforementioned sat would be over twice the size of the 19-meter Kiku No. 8, which currently holds the crown for the largest launched by the Japan Aerospace Exploration Agency, meaning that the newfangled equipment would fit nicely within the confines of today's increasingly shrinking cellphone and still find signal. Interestingly, the ministry isn't looking to get the service going before 2015, so we just might be looking at mainstream antenna-less iterations by that time anyway.

Although most modern phones can go quite a few hours sans an AC outlet, we understand the need for juice in unexpected emergencies, and while the solar-powered charger does a fair job at high noon, you'll probably need a different approach come nightfall. Tackling two issues in one fell swoop is the cellphone-charging flashlight mod, which not only provides a beacon of light for those dim excursions, but also offers up hand crank recharging abilities for your fading mobile. Of course, hacking your flashlight to pull double duty as a manually powered charger is a bit more complex than just picking up a hamster or bicycle-powered option, but you've got to admit, crafting a makeshift charger with spliced cables and a soldering iron is totally MacGyver-approved. So if you're interested in giving yourself (and your handset) a bit longer life when robotic overlords eventually invade our domiciles, be sure to hit the read link for a video demonstration, and do mind the managerial cat on duty.
