Title: hey storm, Interesting article on Nano tubes...

<snip>100-metre nanotube thread pulled from furnace

A thread of carbon nanotubes more than 100 metres long has been pulled from a fiery furnace. The previous record holder was a mere 30 centimetres long.

Carbon nanotubes are stronger than steel and better conductors than copper, but are often just a thousandth of a millimetre in length. By bundling the nanotubes together into much longer fibres, scientists hope to harness their properties on a larger scale. For example, embedding long carbon nanotube threads in plastic would give tougher composites for airplane hulls.

Post by: Stormbringer on March 13, 2004, 11:02:06 am: This stuff is the only thing we have that is strong enough to build a cable reaching a space satelite from the ground. The cable can be used to get a "car" up to geosych and back. This should be much cheaper than rockets or shuttles. The forces acting on the cable including the car are dampened by additional tethers attatched to out rigger satelites. A manufacturing facility and even a shipyard is near the space end. Ships are built in orbit and never have to deal with the gravity well. Thus they can be as large as we like. As an added bonus the thing generates electricity as it cuts the magnetic field or rather its dampers do.
