I'd like a portable generator for my Android device of choice. Would that be Ok? I actually live in an area that can imagine the power grid not being there. Neighbours not far from my place still get some degree of technology. And that some degree means laptops, microwave ovens, satellite TV and air conditioner while being hundreds of miles from the closest power line. You might want to imagine the worst case scenario, but for me it's so unlikely I'd advise anyone to just learn how to cope without slashdot or facebook.
Also, you might want to prepare for the most likely cataclysm: the Internet of zero privacy and high levels of censorship and manipulation. How would you survive that?
Starting with one of the great great GP and TFA, knowing that space is vast, how would people survive separation from the Earth? Would any of you be ready for that?
