100% Biodegradable NANOIL(TM) Ready for Automobiles

Nano Chemical Systems Holdings, Inc. (OTC Bulletin Board: NCSH), (Nanochem or "The Company"), announced that, their latest entry into the multi-billion dollar performance chemical category, NANOIL(TM), a "nano-enhanced" GREEN motor oil. Unlike today's fossil and synthetic oils, NANOIL(TM) is non-toxic and bio-degradable, thus eliminating the current disposal issues with present commercially available lubricants.Nanochem will produce NANOIL(TM) utilizing its nano-technology patent applications and inventions that directly address bio-fuel production for a nano-enhanced line of "green" bio-lubricants. Initial results indicate that these bio-lubricants can perform as well as today's fossil and synthetic oils. Further, the viability of bio-fuel production can be significantly enhanced by utilization of materials needed to be removed from Biodiesel and using these materials as feed stocks for NANOIL(TM). "We can not overstate the environmental impact of "GREEN" motor oil that if sufficiently biodegradable, can reduce or eliminate the need for disposal of crank case oil as a toxic waste, and eliminate that ugly blackline down the center of the freeway lanes where commercial vehicle traffic is concentrated," says Alex Edwards, III, CEO and President of NanoChem."NANOIL(TM) is the first product to be launched in our new 'WHY NOT GREEN' campaign," Edwards concluded. With retailers such as Home Depot and Wal-Mart announcing their own "GREEN" initiatives, the Company anticipates easy acceptance for NANOIL(TM) into the extremely competitive motor oil market. Further, consumers are looking for ways to find green alternatives and there are plenty of consumer awareness programs being directed at the consumer of how toproperly use these new green products and how to dispose of non-friendly old products. "Disposing of used motor oil is a constant challenge for do-it-yourselfconsumers and, though it is never recommended, they will dispose of it in a variety of ways including dumping it into their yard," says Lou Petrucci, COO and VP Sales of NanoChem. "With 100% biodegradable oil, this activity will no longer present an environmental concern."

Benefits of Molecular Manufacturing

Overview: Molecular manufacturing (MM) can solve many of the world's current problems. For example, water shortage is a serious and growing problem. Most water is used for industry and agriculture; both of these requirements would be greatly reduced by products made by molecular manufacturing. Infectious disease is a continuing scourge in many parts of the world. Simple products like pipes, filters, and mosquito nets can greatly reduce this problem. Information and communication are valuable, but lacking in many places. Computers and display devices would become stunningly cheap. Electrical power is still not available in many areas. The efficient, cheap building of light, strong structures, electrical equipment, and power storage devices would allow the use of solar thermal power as a primary and abundant energy source. Environmental degradation is a serious problem worldwide. High-tech products can allow people to live with much less environmental impact. Many areas of the world cannot rapidly bootstrap a 20th century manufacturing infrastructure. Molecular manufacturing technology can be self-contained and clean; a single packing crate or suitcase could contain all equipment required for a village-scale industrial revolution. Finally, MM will provide cheap and advanced equipment for medical research and health care, making improved medicine widely available. Much social unrest can be traced directly to material poverty, ill health, and ignorance. MM can contribute to great reductions in all of these problems, and in the associated human suffering.
Advanced nanotech can solve many human problems.
Technology is not a panacea. However, it can be extremely useful in solving many kinds of problems. Improved housing and plumbing will increase health. More efficient agriculture and industry save water, land, materials, and labor, and reduce pollution. Access to information, education, and communication provides many opportunities for self improvement, economic efficiency, and participatory government. Cheap, reliable power is vital for the use of other technologies and provides many conveniences. Today, technology relies on distributed manufacturing, which requires many specialized materials and machines and highly trained labor. It is a difficult and slow process to develop an adequate technology base in an impoverished area. However, molecular manufacturing does not require skilled labor or a large supporting infrastructure; a single personal nanofactory (PN) with a single chemical supply and power supply can produce a wide range of useful, reliable products, including copies of itself to double the manufacturing infrastructure in hours, if desired. Thus PNs, and many of their products, are "appropriate technology" for almost any setting.

Many diverse problems are related to water: A few basic problems create vast amounts of suffering and tragedy. According to a World Bank document water is a major concern of the U.N. Almost half the world's population lacks access to basic sanitation, and almost 1.5 billion have no access to clean water. Of the water used in the world, 67% is used for agriculture, and another 19% for industry. Residential use accounts for less than 9%. Much industry can be directly replaced by molecular manufacturing. Agriculture can be moved into greenhouses. Residential water can be treated and recycled. Adoption of these steps could reduce water consumption by at least 50%, and probably 90%. Water-related diseases kill thousands, perhaps tens of thousands, of children each day. This is entirely preventable with basic technology, cheap to manufacture-if the factories are cheap and portable. MNT can provide similar opportunities in many other areas. Much water today is wasted because it is almost but not entirely pure. Simple, reliable mechanical and electrical treatment technologies can recover brackish or tainted water for agricultural or even domestic use. These technologies require only initial manufacturing and a modest power supply. Physical filters with nanometer -scale pores can remove 100% of bacteria, viruses, and even prions. An electrical separation technology that attracts ions to supercapacitor plates can remove salts and heavy metals. The ability to recycle water from any source for any use can save huge amounts of water, and allow the use of presently unusable water resources. It can also eliminate downstream pollution; a completely effective water filter also permits the generation of quite "dirty" waste streams from agricultural and industrial operations. As long as the waste is contained, it can be filtered, concentrated, and perhaps even purified and used profitably. As with anything built by molecular nanotechnology, initial manufacturing costs for a water treatment system would be extremely low. Power will be cheap (see below). Well-structured filter materials and smaller actuators will allow even the smallest filter elements to be self-monitoring and self-cleaning. Self-contained, small, completely automated filter units can be integrated in systems scalable over a wide range.

Cheap greenhouses can save water, land, and food: Moving agriculture into greenhouses can recover most of the water used, by dehumidifying the exhaust air and treating and re-using runoff. Additionally, greenhouse agriculture requires less labor and far less land area than open-field agriculture, and provides greater independence from weather conditions including seasonal variations and droughts. Greenhouses, with or without thermal insulation, would be extremely cheap to build with nanotechnology. A large-scale move to greenhouse agriculture would reduce water use, land use, and weather-related food shortages.
Nanotech makes solar energy feasible.
The main source of power today is the burning of carbon-containing fuels. This is generally inefficient, frequently non-renewable, and dumps carbon dioxide and other waste products (including radioactive substances from coal) into the atmosphere. Solar energy would be feasible in most areas of the globe if manufacturing and land were sufficiently cheap and energy storage were sufficiently effective. Solar electricity generation depends on either photovoltaic conversion, or concentrating direct sunlight. The former works, although with reduced efficiency, on cloudy days; the latter can be accomplished without semiconductors. In either case, not much material is required, and mechanical designs can be made simple and fairly easy to maintain. Sun-tracking designs can benefit from cheap computers and compact actuators. Energy can be stored efficiently for several days in relatively large flywheels built of thin diamond and weighted with water. Smaller energy storage systems can be built with diamond springs, providing a power density similar to chemical fuel storage and much higher than today's batteries. Water electrolysis and recombination provide scalable, storable, transportable energy. However, there is some cost in efficiency and in complexity of technology to deal safely with large-scale hydrogen storage or transportation. Solar solutions can be implemented on an individual, village, or national scale. The energy of direct sunlight is approximately 1 kW per square meter. Dividing that by 10 to account for nighttime, cloudy days, and system inefficiencies, present-day American power demands (about 10 kW per person) would require about 100 square meters of collector surface per person. Multiplying this figure by a population of 325 million (estimated by the US Census Bureau for 2020) yields a requirement for approximately 12,500 square miles of area to be covered with solar collectors. This represents 0.35% of total US land surface area. Much of this could be implemented on rooftops, and conceivably even on road surfaces.
Living spaces can be greatly improved: A person's living space has a significant effect on their quality of life. The ability to exclude insects will greatly reduce certain diseases. Thermal insulation can increase comfort and often reduce energy consumption. Water and sewage piping and fixtures increase sanitation and decrease disease. House styles are as varied as cultures, and living spaces cannot and should not be standardized worldwide. However, building supplies and home systems (e.g. power, plumbing) require less diversity, and useful components may be built from predesigned plans. In many areas of the world, something as simple as a water filter or a mosquito net can save many lives. Such small, simple products would cost almost nothing to produce. In areas that already use rectilinear apartment construction, including most inner cities, double-layer, vacuum-insulated wall panels can greatly decrease noise transmission between adjacent living spaces as well as providing excellent thermal insulation. Living space reform cannot be approached as a single problem with an easy solution, but the worst problems can easily be addressed piecemeal.
Computers will be cheap enough for everyone: Molecular manufacturing can create computer logic gates a few nanometers on a side, and efficient enough to be stacked in 3D. An entire supercomputer can fit into a cubic millimeter , and cost a small fraction of a cent. With actuators smaller than a bacterium, a thin, high-resolution computer display will be easy (and cheap) to build. With GHz mechanical frequencies, a mostly-mechanical device can sense and produce radio waves. Thus computation, communication, and display are all feasible with pure diamondoid technology. Computers, PDAs, and cell phones can be cheap enough for even the poorest people on earth to own one, and contain more than enough processing capability for a voice interface for illiterate people. Distributed networking hardware can likewise be very cheap, and distributed networking software, though not trivial, is already being developed. The whole world could get "wired" within a year.
Nanotech can help the environment: Environmental degradation is a serious problem with many sources and causes. One of the biggest causes is farming. Greenhouses can greatly reduce water use, land use, runoff, and topsoil loss. Mining is another serious problem. When most structure and function can be built out of carbon and hydrogen, there will be far less use for minerals, and mining operations can be mostly shut down. Manufacturing technologies that pollute can also be scaled back. In general, improved technology allows operations that pollute to be more compact and contained, and cheap manufacturing allows improvements to be deployed rapidly at low cost. Storable solar energy will reduce ash, soot, hydrocarbon, NOx, and CO2 emissions, as well as oil spills. In most cases, there will be strong economic incentives to adopt newer, more efficient technologies as rapidly as possible. Even in areas that currently do not have a technological infrastructure, self-contained molecular manufacturing will allow the rapid deployment of environment-friendly technology
Improved medicine can be widely available: Molecular manufacturing will impact the practice of medicine in many ways. Medicine is highly complex, so it will take some time for the full benefits to be achieved, but many benefits will occur almost immediately. The tools of medicine will become cheaper and more powerful. Research and diagnosis will be far more efficient, allowing rapid response to new diseases, including engineered diseases. Small, cheap, numerous sensors, computers, and other implantable devices may allow continuous health monitoring and semi-automated treatment. Several new kinds of treatment will become possible. As the practice of medicine becomes cheaper and less uncertain, it can become available to more people.
Removing causes of distress may reduce social unrest: Much social unrest can be traced directly to material poverty, ill health, and ignorance. Molecular manufacturing can eliminate material poverty-at least by today's standards; post-MM standards may be considerably higher. Products of molecular manufacturing can greatly improve health by eliminating conditions that cause disease, including poor sanitation, insects, and malnutrition. Widespread availability of computers and communication devices can provide exposure to other cultures and diverse points of view, and create an understanding of a broader social context in which to evaluate actions and beliefs. (Unfortunately, mass communication also gives demagogues a wider audience, which may undo some of this benefit.) MM certainly will not cure or prevent social unrest, but it will remove many tangible causes of distress.

Introduction to Nanotechnology

Human hair fragment and a network of single-walled carbon nanotubes
What is nanotechnology :
Truly revolutionary nanotechnology products, materials and applications, such as nanorobotics, (are years in the future (some say only a few years; some say many years). What qualifies as "nanotechnology" today is basic research and development that is happening in laboratories all over the world. "Nanotechnology" products that are on the market today are mostly gradually improved products (using evolutionary nanotechnology) where some form of nanotechnology enabled material (such as carbon nanotubes, nanocomposite structures or nanoparticles of a particular substance) or nanotechnology process (e.g. nanopatterning or quantum dots for medical imaging) is used in the manufacturing process. In their ongoing quest to improve existing products by creating smaller components and better performance materials, all at a lower cost, the number of companies that will manufacture "nanoproducts" (by this definition) will grow very fast and soon make up the majority of all companies across many industries. Evolutionary nanotechnology should therefore be viewed as a process that gradually will affect most companies and industries.

Definition of nan'o•tech•nol'o•gy n
So what exactly is nanotechnology? One of the problems facing nanotechnology is the confusion about its definition. Most definitions revolve around the study and control of phenomena and materials at length scales below 100 nm and quite often they make a comparison with a human hair, which is about 80,000 nm wide. Some definitions include a reference to molecular systems and devices and nanotechnology 'purists' argue that any definition of nanotechnology needs to include a reference to "functional systems". The inaugural issue of Nature Nanotechnology asked 13 researchers from different areas what nanotechnology means to them and the responses, from enthusiastic to sceptical, reflect a variety of perspectives.
It seems that a size limitation of nanotechnology to the 1-100 nm range, the area where size-dependant quantum effects come to bear, would exclude numerous materials and devices, especially in the pharamaceutical area, and some experts caution against a rigid definition based on a sub-100 nm size.
Another important criteria for the definition is the requirement that the nano-structure is man-made. Otherwise you would have to include every naturally formed biomolecule and material particle, in effect redefining much of chemistry and molecular biology as 'nanotechnology.' ( as shown fig above)
The most important requirement for the nanotechnology definition is that the nano-structure has special properties that are exclusively due to its nanoscale proportions.

Increase in thermoelectric efficiency by the use of nanotechnology

By the use of nanotechnology to achieve a major increase in thermoelectric efficiency, a milestone that paves the way for a new generation of products - from semiconductors and air conditioners to car exhaust systems and solar power technology - that run cleaner.
Building tiny alloy nanostructures that can serve as micro-coolers and power generators. The researchers said that in addition to being inexpensive, their method will likely result in practical, near-term enhancements to make products consume less energy or capture energy that would otherwise be wasted.

The findings represent a key milestone in the quest to harness the thermoelectric effect, which has both enticed and frustrated scientists since its discovery in the early 19th century. The effect refers to certain materials that can convert heat into electricity and vice versa. But there has been a hitch in trying to exploit the effect: most materials that conduct electricity also conduct heat, so their temperature equalizes quickly. In order to improve efficiency, scientists have sought materials that will conduct electricity but not similarly conduct heat.
Using nanotechnology, produced a big increase in the thermoelectric efficiency of bismuth antimony telluride - a semiconductor alloy that has been commonly used in commercial devices since the 1950s - in bulk form. Specifically, the team realized a 40 percent increase in the alloy's figure of merit, a term scientists use to measure a material's relative performance.
The achievement marks the first such gain in a half-century using the cost-effective material that functions at room temperatures and up to 250 degrees Celsius. The success using the relatively inexpensive and environmentally friendly alloy in bulk form means the discovery can quickly be applied to a range of uses, leading to higher cooling and power generation efficiency.
"By using nanotechnology, we have found a way to improve an old material by breaking it up and then rebuilding it in a composite of nanostructures in bulk form," said Boston College physicist Zhifeng Ren, one of the leaders of the project. "This method is low cost and can be scaled for mass production. This represents an exciting opportunity to improve the performance of thermoelectric materials in a cost-effective manner."

"These thermoelectric materials are already used in many applications, but this better material can have a bigger impact," said Gang Chen, the Warren and Towneley Rohsenow Professor of Mechanical Engineering at MIT and another leader of the project.
At its core, thermoelectricity is the "hot and cool" issue of physics. Heating one end of a wire, for example, causes electrons to move to the cooler end, producing an electric current. In reverse, applying a current to the same wire will carry heat away from a hot section to a cool section. Phonons, a quantum mode of vibration, play a key role because they are the primary means by which heat conduction takes place in insulating solids.
Bismuth antimony telluride is a material commonly used in thermoelectric products, and the researchers crushed it into a nanoscopic dust and then reconstituted it in bulk form, albeit with nanoscale constituents. The grains and irregularities of the reconstituted alloy dramatically slowed the passage of phonons through the material, radically transforming the thermoelectric performance by blocking heat flow while allowing the electrical flow.

In addition to Ren and six researchers at his BC lab, the international team involved MIT researchers, including Chen and Institute Professor Mildred S. Dresselhaus; research scientist Bed Poudel at GMZ Energy, Inc, a Newton, Mass.-based company formed by Ren, Chen, and CEO Mike Clary; as well as BC visiting Professor Junming Liu, a physicist from Nanjing University in China.

Thermoelectric materials have been used by NASA to generate power for far-away spacecraft. These materials have been used by specialty automobile seat makers to keep drivers cool during the summer. The auto industry has been experimenting with ways to use thermoelectric materials to convert waste heat from a car exhaust systems into electric current to help power vehicles.
