Your assignment: Design a post-apocalyptic communication system

  1. I'm a programmer but weak on hardware so I'd appreciate your help. In a novel I'm writing there are about one hundred underground cities housing one million people in the US; the rest of our population is dead. Somewhat smaller percentage of survivors in Europe and Asia. We have several years warning and want to establish a communication system - internet and television - for the survivors, including - if possible - communication with Europe and Asia via undersea cables. The cities have plenty of energy available but there will be none between cities, so I wonder if the distances between nodes will make it impractical.

    Can anyone help me with this? Thanks.

    Sounds like the original design parameter for the internet... so what's wrong with that?

  7. they should use the remaining us nuclear arsenal to broadcast morsecode seismically.

    they can use old USGS equipment if they're a little further away or hard of hearing.
