Yarn Spun from Nanotubes

jabberjaw writes "Nature is reporting that Professor Alan H Windle has spun nanotube yarn by twisting nanotubes onto spinning rods as they come out of the furnace from which they are made. Professor Windle's team used ethanol (carbon source) with ferrocene (catalyst) and thiopene (for thread assembly) to create the structure. To create the tubes a mix of the above chemicals is inserted into a furnace in a jet of hydrogen gas. However, do not get your hopes up yet, the press release also indicates that the yarn has a strength comparable to that of most modern textiles but the groups does state that there is room for improvement. Yes, for those of you wondering, there is mention of a space elevator."

As the fry passes under the sensor it optimizes the fry length and fires a hydraulic piston with a rubber hinge attached to a curved blade, the speed that the piston fires at flexes the rubber hinge so that as it springs back it's speed matches belt. This prevents the fries from being fired off the belt by the knifes. It also accounts for starch build up on the system. All pistons are hot swappable.

      Yes, but such a cheap RLV is also not-yet-existent. Yes, I'd be pleased to see a cheap RLV, but there would be problems once we really start to use the capacity.

      RLV's are loud and polluting. A space elevator has the potential to be extremely efficient and generate no air pollution.

      Another poster has observed that surviving reentry is less stressful with a space elevator--there's no smacking into the atmosphere at twenty times the speed of sound. I suspect that the risk of failure of a space elevator resulting in loss of life is likely lower, though I'll freely admit that we could make engineering assumptions to push that argument either way.

      You can build a space elevator for higher capacity, in principle. Bulky unaerodynamic cargoes can ride the elevator. There's only so much cargo you can put in a practical RLV; for a space elevator you just add more and thicker cables.

As an individual, I could take my Jeep and do it. It's certainly easier than building a railroad.

What if I want some steel girders or a space station module at Point B?

I can even use the original tracks to deliver tracklaying equipment.
