Default Paper published on producing arbitrarily long nanotubes.

Ok, I was engaging in a bit of hyperbole there. But even if these methods
could produce arbitrarily long nanotubes at 1/10th the maximum measured
nanotube strength, this would be a major change in materials science.

Nope, the next stop would be ANYTHING practical.

The lack of flying cars has never been a materials problem. There have
been lots of flying cars built.

I agree there. There has a recent announcement of a quad-copter style flying
transport that is intended to be self-flying.

For one, they're super expensive. But, ignoring the expense for now...

The huge problem with flying cars in my mind is building one that's
simple for a "driver" to operate. The masses aren't going to all get a
pilot's license. Heck, most people on the road shouldn't even have a
driver's license based on how awful they drive and on how many wrecks
they cause. Imagine them all flying cars right into each other!

To make this work, you'd need self-flying cars!

Thanks for taking the time to read it. Right, these now are just proposals.
All of them though would be easy and low cost to test for nanotechnology
research labs.


Everything is always "easy and low cost" until someone has to actually
build something and make it work.

Only in a few niche applications where weight and strength are competing
parameters.

For the vast majority of things there is no incentive to build them from
nanotubes.

No, its simply because theyre a stupid outdated SF concept birthed
from a car-crazed society. Once you have a vehicle that can fly between
locations, it makes zero sense to also make it suitable for driving on
roads. Who in their right mind is going to *drive* anywhere they could
just fly to? Who is going trust that a roadworthy vehicle after miles
of driving is going to remain airworthy?

Eliminate the economics problems and flying cars still make no sense.
Imagine a world where everyone is Superman. Superman does not drive to
the rescue. Only motorheads ever thought flying cars were a good idea.


No, Jimp. Flying cars were and are a good idea unless you think you
can just land anywhere you like. If you fly a GA aircraft, what do
you do once you land it?

You are replying to someone else, not me.

Once you land the plane, you taxi to the tie down area, tie down and
secure the aircraft, then go see the FBO. There will quite often be
a dedicated phone to Enterprise. Don't forget to ask for your Aircraft
Owners and Pilots Association discount.

In the post 9/11 world there is yet another complicaton; all airports
have fences around the operating areas, which means if you are not
based at the airport and have the ability to open and close the gate,
you will have to find someone who does to let you on and off the airport
with a flying car.

Drive it away if you own it and you need an airfield.

Let it fly to its next pick up if its automated - after dropping you off precisely where you want to go.

Nanotube Superfiber Materials
Changing Engineering Design
Edited by:Mark J. Schulz, Vesselin N. Shanov and Zhangzhang Yin
ISBN: 978-1-4557-7863-8

Here's a 2013 book on the subject. Please review

Chapter 14 – Direct Dry Spinning of Millimeter-long Carbon Nanotube Arrays for Aligned Sheet and Yarn

Yoku Inoue

Ultralong multiwalled carbon nanotube arrays (forests) were grown by chloride-mediated chemical vapor deposition, in which iron chloride was used as a catalyst precursor. Highly spinnable millimeter-long arrays were grown with a very rapid growth rate of 100 μm/min. By stacking long-lasting carbon nanotube (CNT) webs, unidirectionally aligned CNT sheets were fabricated. The sheet was highly anisotropic in electrical and thermal properties and due to high alignment of the CNTs in the sheets. CNT yarns were fabricated using the millimeter-long CNTs and a detailed analysis of various postspin processes, including postspin twisting and multiply twisting, and their effect on CNT yarns were studied. Mechanical properties clearly depended on the dimensions of CNTs, where thinner and longer CNTs led to strong and stiff yarns. Large contacting surface areas in the yarns, brought by closer packing with high-aspect-ratio CNTs, were effective for higher van der Waals interaction leading to higher tensile properties. Growth of millimeter-long highly spinnable CNT arrays and the material properties of tailored large-scale CNT structures, including unidirectionally aligned sheets and spun yarns, are described.

http://www.mie.uth.gr/ekp_yliko/2_ma...harts-2009.pdf

Basically, materials that exceed anything known today are already in the lab, and are merely seeking the money to build the tools necessary to make them on a larger scale. The most obvious use is aerospace. Lightweight blow down micro-engines, lightweight high pressure ZBO cryogenic tanks, lightweight airframes, lifting surfaces, thermal surfaces - all can be reinvented using what is known today.

Those that bring these research results to fruition first, and do so reliably and cost effectively, will own the aerospace industry going forward - and challenge many other industries as well.
