Space Elevator to Solve World's Energy Shortage

  1. Nov 12, 2005 #1
    If carbon nanotubes are great conductors, and if a wire moved through a magnetic field generates electricity, then a space elevator constructed out of carbon nanotubes should be able to generate a lot of electricity.

    Maybe too much. I think the carbon nanotubes would melt. Indeed, if there is a "showstopper" for the space elevator concept, this is probably it.:grumpy:

    Carbon nanotubes are 6x times stronger then Iron I don't think they'll melt too easily anyway we should be able to control the amount of eletricty that goes though them.

    ... the earth doesn't exactly have a large magnetic flux density...

    Well, I'm thinking of the NASA tether experiment where they extended a tether from a space shuttle and it burned up because the current was too much. If a tether a few hundred yards can't handle all those amps out there, how can we expect a 50,000 mile tether to handle it?
