Probably true of the lower portion, but maybe not of the upper, depending on materials and design. It seems to me, though, that the cable could be made to have arbitrarily low volume density even in regions where the linear density is high. What does it matter what the diameter of the cable is 15,000 miles up? In fact making the cable voluminous should make it more resistant to impact damage. > I would hope so. However, there are more stable cross section forms. I don't assume any particular cross section. -- John Hasler [EMAIL PROTECTED] (John Hasler) Dancing Horse Hill Elmwood, WI -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
