Well, let me try again: Since the cable will, to some
(significant) degree, vibrate mechanically anyway, one
method of gathering power for use along its length (such
as powering elevator cars from electricity) could be by
scavenging this mechanical energy, rather than by
beaming it from a
source at the base or counterweight,
etc. Bungston has it absolutely right, btw, this
vibrational energy is commonly known as twang... Any
technological development would have to be scaled up
from the microelectrical devices now working--I guess I
was simply pointing out that this might be not only a
possible form of energy to use on a space elevator, but
also might to some degree serve as a damp on such a
structure.

The page linked to says it's for micro electrical mechanical systems ... I doubt that it would be sufficient for space elevator cable cars. |
|

Where is all this vibrational energy going to come from? The cars going up the cable, by chance? |
|

I don't think that this sort of thing belongs. Post the idea, or don't post at all. This has a spammy smell.... |

a) wind generators = baked
|
|
| |
b) previous patent = baked
|
|
| |
c) [marked-for-deletion] see a) and b) |
|
| |
Would coating the cables in some sort of magnetic custard help? |

I think you are supposed to pluck them with a big pick. A sort of giant space bass. |
|
| |
Or bowed, with a big honkin' rainbow. Depends on your point of view, of course. |

It would make a neat toy (I haven't looked at the link but I presume the cars inch up every second quarter-wavelength of a vibration) |
