rebuilding post collapse.

[Skean Dhude]

I'm with Paul. The time when coal was just below the surface is gone. It is deep underground and without power for the air and lifts you just can't get to it. Making electronic parts is a specialist business. For most of us it will be living on what we have. For most eventualities we will be back to the Iron age. Only a couple of scenarios have us being able to return to normal in a reasonable timescale and that would be the one where we still have power and a few specialists survive. Not knowing exactly what will happen means that it is possible that be could be back to normal in a few years. That could only be if an event was localised.

You are right though about having the knowledge and eventually we could build back but it will be well into the future. I have books on much of what is needed for rebuilding but will they survive. Some will and they will be owned by the Wizards of the future. Perhaps somewhere there will be equipment and buildings with some of this kit in but IMO it won't be for several decades.
