I'm tossing around a story idea I had. Basically, there's a zombie apocalypse, and for several years small scattered groups of survivors are struggling and hiding. But the zombies slowly decay, and eventually die. And since most of the human population became zombies all at the same time, they all die at the same time, too. The main characters were at a fertility clinic (a mix of clients, donors and workers) when the zombies first attacked, and they managed to get the place fortified and safe. The clinic had an uninterruptible power supply capable of keeping the freezers running for a week without power. During that time, they realize this isn't going to blow over quickly, and most of humanity is gone. So someone decides that they should do whatever they can to keep the freezers running and preserve the genetic diversity stored within them, because if humanity will ever recover, they'll need to counter the effects of inbreeding. They succeed in keeping the power on throughout the apocalypse, and when nearly all the zombies drop dead, they decide to send out a van with sperm to scout out for people and try to convince as many women as possible to have babies conceived by sperm donors. I have two big questions. First, how will they keep the power on? Anyone know what a medical grade UPS needs, and where you'd scavenge it in a zombie infested city? I'm thinking eventually they'd set up solar panels and possibly wind power, but would that be enough? Second, what are some of the reactions they're likely to get once they're on the road? Both positive and negative.
