So how do we deploy the ring around the earth? Oh wait we can't, large space tethers are unstable.

Oh and stability has not been demonstrated for large perturbations for the discrete skyhook case.

>> almost zero
Prove it. Now if you do the math the probability of a tsunami taking out the generators at fukushima in a 1 year period was almost

>>they are in orbit
They are NOT in orbit. In order to support the skyhooks, the skyhook must change the direction of the cable.

It has been shown that long flexible structures in space can behave in very strange ways because of how the mass is distributed: http://www.wseas.us/e-library/transactions/mathematics/2008/Ultra-long.pdf

Pic related, a possible pentagonal orbit for a very long tether. So uh, its probably not just going to float away and could cause a kessler syndrome.

>> keep them away from populated areas

Ok and how do you do that with a ring that goes around the whole earth?

>> parachutes
And how do you put enough parachutes over the whole damn tether to even be effective?

>> 1-3 years
Ok, so you are going to replace all of Earth's electrical infrastructure in 1-3 years?
For that matter how are you even going to build this thing in 1-3 years?

>> 1c/kwh
If you do that, your 2 GW solar power satellite takes 32 years to pay back its construction costs

Now if electricity gets cheaper because we invent some new cheap way of generating electricity after you finish construction you're screwed.
