We've become accustomed to living in a throwaway society because there is always a replacement for something that breaks, but it would be sheer folly to depend on anything we couldn't replace when it wore out. Rod. Engineering skills would have to be rediscovered and taught, but in the short term existing hydroelectric dams fortunately need little maintenance. With multiple generators and turbines, even if several fail there's still a lot of redundancy left. Even if, by pure fluke, out of the fraction of the population left over, the tiny percentage that knew how to run a power station (do you?) just happened to find their way to them (How? on foot? on horseback), they'd realise that it was only a stopgap. There would be no hope of repairing or replacing anything. You might be able to teach the next generation how to tend a generator, but without an upbringing in a technological world they'd have an increasingly limited understanding of how it worked, eventually just knowing what switches to press to make it work. (This is, after all, the extent of most people's understanding of technology now). As little as one generation down the line, explanations in scientific terminology would be meaningless mumbo-jumbo to a rural society with no laboratories to demonstrate any of it - just stuff the older people would expect you to memorise to be allowed to tend the great machine. Within three or four generations, if it was still working, they'd be worshipping the thing. Then it would break down. Rod. It wouldn't last that long anyway - the hydro stations and power generation generally take a load of people to tend and maintain the equipment, not just on site but all those substations etc. Given there would only be a few survivors - even if they all congregated in a cleaned up town there would be too much electricity generated and it'd need to be transmitted to the grid. It'd fail without the army of bods to maintain it daily. So we are back to portable generators, either small ones that you see on campsites use or big ones like the military have or like you see on Motorway projects. There are loads of them , find a laod of new ones and store them properly and that'll be power for the next 50yrs , if the fuel keeps ( diesel should be the option then it'll still run on poor diesel). No reason to believe that if they weren't stored properly in the pacakging that they wouldn't be OK in 50 yrs. I've seen VW engines from the 60's new old stock still in plastic on pallets found in a warehouse, with fuel and electrics fitted they were perfect. No good for the very long term I suppose, they'd need to be making windmills or water wheels in the meantime. |

Rod. -- Except that reality simply doesn't follow that model. Very few people actually panic in an emergency, the overwhelming reaction is denial and an attempt to cling to what they know for as long as possible. Except where the threat is immediate and certain, such as a hurricane approaching a coastal city and they are being urged to evacuate by government, most people stay where they are, even in war when their city is being devastated by bombing. They will seek whatever shelter they can but most don't flee. Add to that the government's likely closure of many transport routes to maintain access for military and other official transport, and preserve fuel, and the idea of vast stretches of motorway or other main road blocked by vehicles is unlikely, though urban roads might become gridlocked. After the initial die-off, when survivors have exhausted what supplies they have and the stench of decay becomes too much, there will an exodus though never complete; some with less sensitivity and stronger stomachs will always stay to take advantage of the resources in the city. Having lots of rotting corpses around isn't actually as big a health risk as is usually thought, provided you take reasonable hygiene precautions of yourself, your immediate living area and especially any food and water you use. And whether in city, town or farm, when immediate needs for food, water and fuel are satisfied, there will always be time for other things. There will also be older and less fit survivors in groups, who will either have useful knowledge or who will become the researchers and teachers, as is the case in 'primitive' societies all over the world, while the younger and stronger ones become the hunter-gatherers or gardner-farmers. And as always happens, leaders will emerge, some benign others self-serving, who will gather and direct groups. There will be some individuals who will revert to a lone, feral existence, many of them with severe psychological problems, but there has never been a situation, even in the worst of circumstances, where it has been a total one-on-one dog fight for the last sip of water or scrap of food. People adapt. |

I've had batteries last nearly ten years in my old vans . Get a new one off the shelf in a car parts place , charge it up , use it a few hours a day and it'll last a decade I reckon. |
