Turning Clay Into Nanotech

The people at Natural Nano have found that hallousite clay can yield a natural source of nanotubes.The clay, found in Utah, is a natural nanomaterial with remarkable properties. Now, NaturalNano's team of scientists is developing methods of separating out the nanotubes and processing them for use in some 200 commercial applications, such as additives in polymers and plastics, electronic components, cosmetics, and absorbents.

A Car That Makes Its Own Gravy

How would you like a car that makes it own fuel? A unique system that can produce Hydrogen inside a car using common metals such as Magnesium and Aluminum was developed by an Israeli company. The system solves all of the obstacles associated with the manufacturing, transporting and storing of hydrogen to be used in cars. When it becomes commercial in a few years time, the system will be incorporated into cars that will cost about the same as existing conventional cars to run, and will be completely emission free.

You Thought The Smart Cars Were Small

This from Nature:
They measure just 3 by 4 nanometres: a million of them parked bumper to tail would cover the length of a flea. And they are stripped down to the absolute basics: just a chassis and two axles with wheels at either end.

But they move. Using a powerful microscope, James Tour and his coworkers at Rice University in Houston, Texas, have watched their 'nanocars' trundle over a layer of gold1.

The axles and chassis are made primarily of carbon atoms linked into rigid rods that form an H shape. At each axle tip, the researchers attached a ball-like wheel made from the football-shaped carbon molecule C60.

The key question was whether these diminutive vehicles truly roll over a surface, or just skitter about because of their thermal energy, as many molecules do.

Tour and his colleagues claim that the wheels must indeed be turning. When they used the fine tip of a scanning tunnelling microscope, a device normally used for imaging at the atomic scale, to attract the nanocars and pull them along, the cars moved forward but not sideways. That's just what you would expect to happen if the C60 molecules were rotating on an axis. Occasionally the cars pivoted and took off in a new direction, making zigzag paths.

Three-wheeled nanocars with tripod axles could only turn in circles, again as would be expected if the wheels were revolving.

"This is really exciting", says materials scientist Henry Hess of the University of Florida in Gainesville, who has used biological molecular motors to drive nanoscale objects over surfaces.

Open Source Energy

The Open Source Energy Network is a great resource for all of the freelance power generation concepts. More than that, they talk about current topics. This week, they're all about the Katrina spawned oil shortage and gas price gouging.
There, I learned about this wild device: the Stirling Engine (2). A single wheel driven by part of a piston's action from a heat differential. The rest of the drive comes from the remainder of it's action. It's very smart and it's a centuries old idea:

Devices called air engines have been recorded from as early as 1699 around the time when the laws of gasses were first set out. The English inventor Sir George Caley is known to have devised air engines c. 1807. Robert Stirling's innovative contribution of 1816 was what he called the 'Economiser' now known as the regenerator which acts to retain heat in the hot portion of the engine as the air passes to the cold part and thus improve the efficiency.

During the nineteenth century the Stirling engine found applications anywhere a source of low to medium power was required , a role that was eventually usurped by the electric motor at the century's end.

It was also employed in reverse as a heat pump to produce early refrigeration.

In the late 1940's the Philips Electronics company in The Netherlands were searching for a versatile electricity generator to enable worldwide expansion of sales of its electronic devices in areas with no reliable electricity infrastructure. The company put a huge R&D research effort into Stirling engines building on research it had started in the 1930s and which lasted until the 1970's. The only lasting commercial spin-off from this for Philips was its reversed Stirling engine: the Stirling cryocooler.

Electronic Paper

I saw that the tide was coming when I saw the XML specification for electronic paper display, I thought it was close. Then I saw the development kit. The kit itself is kind of ugly-- but imagine what the kit for first TV would have looked like. There will have to be several passes of failed experimental models in the marketplace before someone comes out with transistor radio equivalent of electronic paper: cheap, ubitiqitous and handy. To augment the power of electronic paper, gumstix computers will likely play a large role.
Where is this going? I remember the most common complaint of books on computer: they're not as handy as books. Well, what if you either take 500 sheets of electronic paper, plug the book into a USB connection and the pages are zepped with new static text. This week your book is Moby Dick; next week, it's the Art of War. What is more likely is that you will take one sheet of paper that has a bulge for a USB port and four more bubbles. Plug in the paper, the book is zapped into the electronic paper: one sheet of electronic paper. Then, the bubble buttons are for backwards and forwards movement. The problem is that model takes power to rewrite the paper. So that model will take some time.
If electronic paper can become very cheap and widespread is may give a new woe: revisionism. The progress of the DMCA and digital rights management may mean that you can only commit the official source of a document to electronic paper. When they revise the book, you can get a free revision. When they revise the material with a double-plus revision, your old version will be illegitimate; you won't be able to commit it to electronic paper. Voila! Already, people who are trying to free their own cellphones from manufacturer and reseller lockdowns are getting slapped with DMCA violations.
With the tap of some keys a futuristic Winston Smith can remake your edition. You won't keep copies you pay for on your own machine--- not when you have wide open access to the Internet and you can get the document from the source whenever you want it. They'll handle versioning for you. Before you know it, your electronic paper will have nothing but good speak.

FAA clears way for Space Elevator testing.

From from Space.com and TechZonez
The LiftPort Group, the space elevator companies, announced September 9 that it has received a waiver from the Federal Aviation Administration (FAA) to use airspace to conduct preliminary tests of its high altitude robotic "lifters."

The lifters are early prototypes of the technology that the company is developing for use in its commercial space elevator to ferry cargo back and forth into space.

The tests, which are planned for early fall, will simulate a working space elevator by launching a model elevator "ribbon" attached to moored balloon initially up to a mile high. The robotic lifters will then be tested in their ability to climb up and down the free-hanging ribbon, marking the first-ever test of this technology in the development of the space elevator concept.

According to Michael Laine, president of the LiftPort Group in Bremerton, Washington, the FAA go-ahead is a "critical step" in the ultimate developing of the group's LiftPort Space Elevator concept.

Nanoshells: Using Nanotechnology To Harvest Light for Biomedicine

USING NANOTECHNOLOGY TO HARVEST LIGHT FOR BIOMEDICINE

<>Professor Naomi Halas, from Rice University in Texas, is a leader in practical applications of nanotechnology in the diagnosis and treatment of cancer. She has received the Breast Cancer Innovator Award from the U.S. government and her research includes development of nanoshells, a new type of nanoparticle designed to selectively absorb or scatter light in a special wavelength region where light penetrates several inches into the body, making virtually all soft body tissues optically accessible. Halas will discuss these non-invasive applications and how they may change the way doctors practise medicine.

Making Ice Without Electricity

According to SlashDot:
Time Magazine is running an article telling us how Dave Williams is trying to make ice for third-world applications using the Hilsch-Ranque vortex-tube effect (first developed in 1930 by G.J. Ranque-- then improved in 1945 by Hilsch), where swirling air is split into hot and cold components." The method is horribly inefficient but Williams is hoping it could yield helpful results in areas where electricity is really not an option."

Cooling is a small deal for people nowadays but think of what cooling can do: keep food safe; keep medicine safe; cool tired people in the third world. Also, traditional air conditioners and refridgerators have something in common: they're lousy heaters. Run a fridge and it will raise the temperature of the room a little in exchange for cooling its interior alot. All those air conditioners that run in the summertime do three things: expend electricity; dump heat; and cool rooms. It would be nice if there were a device that had the net effect of lowering the temperature.

Rollable Screens


I think I would officially, like to have one of these. The Philips Concept Readius is a prototype of a connected consumer device for business professionals. The device implements a pocket-sized e-reader withouth sacrificing readability, mobility, performance, or weight.

Not Hot Air: A Cool Air Car

The people at MDI are trying to bring to market a car that runs on compressed air. MDI is a French company (Moteur Developpment International). You fill up a tank with highly compressed air, the air jets into a system of pistons that drive the engine like an internal combustion engine.
Discovery's Daily Planet highlighted the "air car". They claim it is "the world's cleanest car." The car actually emits cold air (below zero degrees celcius) as exhaust. Does that mean it will contribute to global cooling?
They are planning to release mini-cars, vans and sedans. If they could put an in-car compressor into the vehicle, I wonder if you could drive up to a gas station's air pump, fill, compress, top-up, compress, repeat? That means you could abuse the existing infrastructure. Now, that would be a swell F-U to the oil companies.

The Singularity

I love concepts that tie into the viridian future that we're a part of. But what is progress without the move forward: smaller, cheaper, faster, better. What if our headlong technological charge meant that wind power, fuel cells, wifi and rest of it were just a phase. What if this stuff had the longevity of the 8-track? What if the approach of nanotech and super computing gave us "the singularity"? We're on one side of the singularity, approaching a crazy technological future. The singularity makes everything possible: open ended longevity, intelligent computer, space travel-- the works. Well, that's the theory. Part of the concept of singularity is that which lies beyond cannot be imagined. It would be like Shakespeare writing a Java applet.

This is a cool think piece on the concept of "Singularity.":
The quote I like best:
"It's hard to say precisely what "strong superhumanity" would be like, but the difference appears to be profound. Imagine running a dog mind at very high speed. Would a thousand years of doggy living add up to any human insight?"

Speed != better wiring is a good concept to remember. After all, there are 3.2 Ghz machines out people's desktops. In 1994 when PCs cracked 100 Mhz (0.1 Ghz), did people think that machines with 32x the speed would still jam up? Or, did they think they would be translating foreign languages in real time? We give money to Wintel for their faster machines. Why not wait for a better machine? Mac's move away from Motorola to Intel will only speed this rut. We are in the latter era of Moore's Law where new chips have to be very fast and are very costly to R&D. That means that AMD, Intel, Motorola and a small list of others have to be careful with what they release. If someone comes out with "self aware" architecture or architecture that could allow for a self-aware machine, they will have to justify it to the masses who only wanted the next version of Word.

That architectural jump has be made. When you want to do some hammering, you buy a hammer. When you want to build a pulley, sure you could build one using hammer in some way, but it isn't really going to work. To make a self aware machine, we have to abandon the x86 architecture, or relegate it to some backward task.

The thought I've had for an SF story is the idea of a "bloom." A chunklet of code that, when it's executed, it causing a cascade of von-Neumann style code writing to make the executing machine self-aware. The problem is the simplicity of neural nets/chaos in nature versus the complexity in computer science. If you throw a bunch of water onto a dirt field-- so much so that you get canals and rivulets of water-- the pattern of those courses has a determinism. Reproduce the experiment and you will find similar results in successive experiments. If you could throw that same easy ability to go left or right into a path of code execution, you could get this going on. The problem: it isn't that easy. Maybe it is just that easy.

Other stuff on The Singularity. The best part: an exchange that paints a TV reporter as retarded.

Nanotech: Boffins build cancer-spotting nanobelts

This from the Register:

Research scientists at Georgia Tech have built nano-scale detectors so sensitive that they will be capable of spotting individual cancer cells.

The detectors are based on a new kind of quasi-one dimensional nano material, dubbed nanobelts or nanoribbons, which can be made from a variety of materials, like zinc or tin oxides. They are typically between 30nm and 300nm wide, and can be a few millimetres long.

The semiconducting nanobelts, first synthesised in 2001, can be tuned to exhibit certain behaviours. Introducing oxygen vacancies can affect their conductivity, surface and optical properties.

The Viridian Mindset

Bruce Sterling went on a rant a while back about Viridians vs. Greens. The Green movement is all about wheat skirts and kilns. Viridian is about remaking society so that we can fit our large species into its small small on the Earth. If that takes technology-- even crazy technology, then so be it.
