| Great points and the most obvious beneficiaries would be the existing, large tech companies--the natural partners of the research companies because of the latter's required capital spending once the technology becomes more feasible. This will continue to stretch out Moore's law; and obviously, make for faster, lighter, and stronger planes for Boeing and Airbus stretching well into the 21st century. |

NASA ain't exactly "commerical." That's one expensive cable shielding.
Scale seems to be the Achilles-heel for hard nanotech product. The irony here is almost decisive in terms of an investing theme to my mind. No doubt incremental progress will continue to be made over the years but as an adjunct to major chemicals/materials concerns' R&D. Considering how little we're doing with carbon-fiber already (and how Boeing/Aribus have suffered the tortures of the damned in this department) I'd be surprised if we even have a single commercial powerline up in a decade's time. Against this there is a clear incentive (as well as govt. mandates in the auto industry for example) for faster lighter and a more general need to substitute for pricey alloys and copper. Note bene: first mover here, for all the hype, is government. What's the matter Wall St., can't do the time? Thought so.
I'd be placing my bets, incrementally and obliquely here if at all. Love to be proven wrong.

ID#: 10-050-0020
Agency: NAVY
Topic#: 10-T050 Selected for Award
Title: Innovative Concepts for Lightweight Composite Sandwich Systems for Complex Shapes
Abstract: &nbs The TM2 team proposes Alcv™, an innovative Al composite material with stellar corrosion resistance, better elongation, formability, and strength performance beyond most Al alloys. High strength Al covetic is an Al alloy infused with 5% or more covalently bonded nano Carbon. TM2 coined the term “Covetic” to ¬describe the alloy microstructure where nano C is infused into the molecular structure and serves as a covalent net that binds the Al. This material offers favorable nano tailored properties including thermal conductivity. Alcv™ material has synergistic properties due to the nano C infusion that produces a fine grain structure. Alcv™ 6061 covetic extruded lab samples have demonstrated exceptional elongation, toughness and corrosion resistance superior to the baseline Al 6061-T6. Alcv™ foam will be fabricated with the same technique as for commercial Al foam. Alcv™ foam can be fabricated because lab experiments show that when the Alcv™ is melted the Al and nano Carbon do not separate and thus the foam will retain the covetic corrosion resistant and thermal conductivity properties. The high specific surface area, low density and closed cell Alcv™ foam offers a combination of properties ideally suited for this Navy application when coupled with Alcv™ face sheets. |

The concept of the space elevator is getting more mainstream by the day:
http://money.cnn.com/2009/12/07/smallbusiness/space_elevator.fsb/index.htm?cnn=yes
| Quote: | The long shot is getting shorter all the time. In September a team of physics professors from York University in Toronto showed how they could build a tether made of Kevlar and inflate it with helium. The catch: It could reach an altitude of only 12 miles, making it more suitable as a communications tower than an elevator to the stars. (Still, tourists could see the Earth's curvature from the top.)
The main trouble with a true space elevator is that we don't yet have materials strong enough to build the cable. The miracle fiber known as carbon nanotubes is getting stronger by the year and is already being used for body armor. If progress continues at the current rate, we should be able to build an elevator-ready tether in a decade or so. But if not, all bets are off.
Then there's the funding problem (estimated elevator price tag: $20 billion, or about a fortieth of the economic stimulus package). So far NASA has ponied up $4 million toward Elevator: 2010, an annual challenge that consists partly of teams competing to build the strongest tether. Japan's space agency has committed itself to the goal of building a space elevator, which it thinks it can do for $10 billion -- though it hasn't yet set a Kennedyesque deadline. |

It's been determined that a doctor with a necktie is as dangerous as a doctor who never washed his hands.
Nanotech to the rescue. Clothes so smooth everything falls off--including dirt! Never wash again.....no we've come full circle.

Honda announces major breakthrough in the creation of metallic carbon nanotubes - upping the success rate from 25-50%, to as high as 91%:
http://www.detnews.com/article/20091001/AUTO01/910010493/1148/auto01/Honda-announces-research-breakthrough
| Quote: | In the Oct. 2 issue of Science magazine, researchers from Honda Research Institute USA, Purdue University and the University of Louisville describe a breakthrough in controlling the formative process.
Past efforts to produce metallic carbon nanotubes yielded a success rate of only 25 percent to 50 percent. But Honda has achieved a success rate of 91 percent metallic conductivity for grown carbon nanotubes.
Honda says the findings open new possibilities for miniaturization and energy efficiency, including much more powerful and compact computers, electronics, batteries, solar and fuel cells. |

Article discusses the current safety concerns and lack of FDA regulation of nanotech-based products - but also asserts that further advances are inevitable and will have a strong impact on our society:
http://www.palmbeachpost.com/business/content/business/epaper/2009/05/24/a1a_nanotech_0525.html
| Quote: | George Burdock, president of Burdock Group, an Orlando-based toxicology consulting firm, said that while nanotechnology is being used widely in dietary supplements - such as calcium - widespread use of nanotech in foods is three to five years away.
"Nanotechnology done the right way is an expensive proposition, and the profit margins for foods are too thin to allow wide applications of nanotechnology just yet," Burdock said. His firm is working with several clients to ensure their products are safe.
If proper safety reviews are carried out and nano-sized particles are determined safe, consumers could see nearly infinite benefits, Burdock said. For example, the amount of an expensive ingredient could be decreased. Improved packaging could lead to longer shelf life for foods typically consumed fresh.
And, despite the questions, the industry is expected to continue to grow. Global research and development investment totals nearly $9 billion a year, according to the Project on Emerging Nanotechnologies; discoveries likely to lead to new medical treatment and tools, efficient energy production, storage and transmission, access to clean water and stronger, lighter materials - to name a few.
"Nanotechnology is said to have the same potential impact on society as did the Industrial Revolution," Burdock said. "Our job is not to stand in the way of potentially beneficial technology, but to make sure it is used in a safe manner." |

Bayer builds first production plant of carbon nanotubes:
http://www.reinforcedplastics.com/view/1720/bayer-builds-production-plant-for-carbon-nanotubes/
| Quote: | Bayer’s Baytubes® multi-wall carbon nanotubes are typically used in a polymer matrix or in metal systems to produce tough, strong, lightweight materials. The company says the product can be used in a broad spectrum of applications, such as rotor blades for wind turbines, transport containers and sports equipment.
A pilot plant with an annual capacity of 60 tons has been in operation in Laufenburg, Germany, since 2007. Production involves a catalytic process in which the carbon nanotubes are obtained from a carbon-containing gas at elevated temperature in a reactor.
Bayer MaterialScience LLC recently obtained regulatory approval from the US Environmental Protection Agency (EPA) to sell Baytubes in the USA. The approval covers the Baytubes C 150 P and HP grades that are currently produced in the Laufenburg plant. |

Behold! a new....commodity:
http://www.wired.com/science/discoveries/news/2007/11/russian_nano
| Quote: | Profits in Nanotech Come From Intermediate Products, Not Raw Materials
Lux Research Finds Nanointermediates Generate Twice the Profit Margins of Nanomaterials and Nano-Enabled Products
updated 5:00 a.m. AKT, Thurs., Jan. 22, 2009
BOSTON, MA - While it's widely believed that any product enabled by nanotechnology will have the potential for huge profit margins, the fact is that many nano-enabled products are only incremental improvements with small premiums. To assist decision makers in identifying the most profitable opportunities, a new report by Lux Research finds that nanointermediates -- intermediate products, such as coatings, memory chips, and catalysts, improved by nanotechnology -- garnered an aggregate net profit margin of 9% in 2007 -- a figure that will expand to 15% in 2015.
"The real opportunities for nanomaterials have become clearer," noted Jurron Bradley, Ph.D., Senior Analyst at Lux Research and head of the firm's Nanomaterials Intelligence service. "Because of nanotech's broad applicability, understanding the maze of opportunities and filtering hype from reality isn't trivial. Nanotech's winners focus on nanointermediates in the key industries we've identified."
To gauge nanotech's commercial impact, Lux Research used its value chain framework to measure and forecast adoption across four major industry sectors -- manufacturing and materials, electronics and IT, healthcare and life sciences, and energy and environment -- from 2004 to 2015. The report, entitled "Nanomaterials State of the Market Q1 2009: Cleantech's Dollar Investments, Penny Returns," is a result of more than 1,000 primary interviews conducted with technology developers and concludes that:
"Nanotech's impact on the energy and environment sector is real, but the disproportionate activity in the field doesn't look justified," Bradley added. "Still, while those applications account for only a small percentage of the revenues from nano-enabled products, energy-based nanointermediates -- such as batteries, capacitors, and solar cells -- can still be a smart bet."

US Steel's "alloying" of furnace coal alone has probably been more profitable.
