If current news is any indication, Nanotechnology is poised to play a significant role in the development of clean, less expensive energy. The potential of nanotechnology for solving some of today’s greatest energy challenges is vast.

Nanotechnology refers broadly to a field of applied science and technology whose unifying theme is the control of matter on the molecular level in scales smaller than one micrometer, normally 1 to 100 nanometers, and the fabrication of devices within that size range. For scale, a single virus particle is about 100 nanometers in width.

Encompassing nanoscale science, engineering and technology, nanotechnology involves imaging, measuring, modeling, and manipulating matter at this length scale.”

At this size dimension, the physical, chemical, and biological properties of materials differ in fundamental and valuable ways from the properties of individual atoms, molecules, or bulk matter. The properties displayed at the nanoscale create a host of potential innovative uses for nanomaterials. One of these uses includes the creation of exciting and revolutionary energy applications. These potential nanoscale energy applications apply to a host of different sources of energy, including hydrogen, geothermal, unconventional natural gas, fission, and solar energy.

While hydrogen is an energy storage medium, it is not a primary energy source. Therefore, full realization of hydrogen as an alternative energy source is frustrated by gaps in technology, which do not precipitate the efficient and cost-effective storage and transport of hydrogen. Nanoscience provides new approaches to basic questions about the interaction of hydrogen with materials to enable the efficient and cost-effective storage and transport of hydrogen.

Applying nanotechnology to geothermal energy increases the opportunities to develop geothermal resources by enhancing thermal conductivity or aiding in the development of noncorrosive materials that could be used for geothermal energy production.

The recovery of unconventional sources of natural gas is yet another potential application of nanotechnology. Unconventional sources of natural gas include tight sandstones, shale gas, and coal bed methane. Nanotechnology applications may prove useful in accessing or exploiting these unconventional natural gas sources. For instance, nanocatalysts and nanoscale membranes may prove useful in assisting in Gas to Liquids production. Furthermore, certain nanostructured materials may assist in compressed natural gas transport.

Nanotechnology may also prove useful in solving the waste problems of the nuclear energy industry. For instance, certain nano-engineered barriers may prove useful in preventing the migration of or containing nuclear waste products.

Nanotechnology applications may assist in making solar energy more economical. Nanoscience can be utilized to improve the efficiency of photovoltaic cells, creating cost-efficient conversion systems, effective solar power storage systems or even the generation of solar energy on a larger scale. For instance, “nanopatterning” can artificially change the optical properties of materials to allow light to be trapped in solar cells.

Nanotechnology might someday allow for more powerful, more efficient and less expensive energy generation, storage transmission and distribution. Nanotechnology is being used to optimize production from existing energy sources and to exploit new sources such as geothermal, liquefied natural gas, nuclear and solar energy. Nanotechnology is also improving and opening new possibilities for the transmission and storage of energy, especially electricity and possibly hydrogen in the future. Nanotechnologies have the potential to reduce energy consumption by making it possible to manufacture lighter and/or more energy efficient cards and appliances. Even though nanotechnology is a relatively young field, the potential for future nanotechnology applications within the energy industry could turn out to be one of the most important technological developments of our time.

Tatiana Velitchkov asked:


People show their emotions in many diverse and specialized ways, some of which a computer can be programmed to detect. By employing nanotechnology, a camera and image analysis software, some computers are able to observe a user’s body language and, with proper programming can accurately interpret a person’s posture, restlessness and various facial expressions like grimacing, smiling or scowling. Nanotechnology advances provide onboard sensors which can monitor heartbeats, breathing rates, fluctuations in blood pressure, and other subtle body changes such as skin temperature and voice inflection.

Because human skin has the capability of transmitting electric signals which can be utilized as a method of transmission, nanotechnology researchers have already been able to develop computers that are designed with nano sensors that have the uncanny ability to actually ’see’ and ‘hear’ the people using them. Inevitably it is only a matter of time until the technology is available to create a computer that can readily identify whether their users are in high spirits or in a bad mood.

With ever advancing nanotechnology equipped computers, scientists figure it is entirely possible to develop a computer that is able to interpret a user’s mood via input it receives based on body language, voice tone and facial expressions and that it will be programmed to adjust itself by providing images designed to provide a feeling of comfort and serenity. Since emotions are ambiguous, transient and ultimately difficult to interpret, it would be very difficult for a computer to accurately construe the many human mood variances, regardless of how advanced the nanotechnology utilized. Therefore, in order to operate with any modicum of precision, a user would have to input the required data in advance.

Nanotechnology, with its sensor based abilities, gives programmers little problem with ‘intelligence’ based activities such as diagnosing a medical condition or participating in a game of chess, yet even with the major advancements in nanotechnology in recent years it is still somewhat of a challenge to design computers that accurately simulate human sight, audio functions, language interpretation and/or motor control.

Human vision and other sensory perceptions have evolved over billions of years and the how and why of their operations are still difficult to understand and/or simulate, while things like mathematics are explicitly taught and are, therefore, easier to express in a computer program.

Programmers are also attempting to employ nanotechnology advancements into programs that they expect to be able to accurately determine a person’s innate wishes regarding resuscitation should they fall ill and not be able to make that decision for themselves. Although, theoretically this information would be beneficial to medical teams, caution should be exercised whenever we allow a machine to determine matters relative to ethics. Regardless of the technology involved, machines are not equipped to differentiate between what is intrinsically right or wrong.

Shane Morgay asked:


Automakers are constantly incorporating the most advanced technology in their lineup. This time around they are planning to use nanotechnology to come up with spectacular vehicles. Two of the most sought-after vehicles are Acura FCX 2020 Le Mans and Volkswagen Nanospyder.

Recently, automakers have unleashed their environment-friendly concept cars that are expected to be manufactured using nanotechnology. The latter is a technology of building tiny machines using functional systems at a molecular scale. According to experts, nanotechnology, in its original sense, means projected ability to assemble items from the bottom up, utilizing techniques and tools being developed these days to make complete, high performance products.

Nanotechnology works from the bottom to the inside of the machine called personal nanofactories (PNs). Using mechanochemistry, nanotechnology will facilitate control at the nanometer scale. A nanometer is one billionth of a meter. Basically, it is about the width of 3 to 4 atoms.

One of the striking future cars presented is FCX 2020 Le Mans from Acura. Said car is envisioned to be powered by advanced auto parts from the automaker. It will also be using Honda car accessories to boost its ergonomics and comfort.

Acura FCX 2020 Le Mans appears like a Batmobile. The difference is that it uses lightweight and recyclable materials. Moreover, it is equipped with a hydrogen fuel cell drivetrain that makes it an environment-friendly car. Its molecular nanotechnology made it lighter and more manageable than present day cars.

Another viable future car is Volkswagen Nanospyder. The captivating car is made up billions of spore-like nanobots. The car is inclusive of mouth, eyeballs and other Volkswagen car accessories including tiny logos.

One of the exciting features of this VW Nanospyder is the ability of its lead bots to pick up impending collisions. Aside from that, the information can be sent away to support particular sections of the car.

Analysts in the auto industry are expecting a greener car future because of nanotechnology. In fact, there have been interesting concept cars submitted in the upcoming Los Angeles Auto Show’s Design Challenge. The latter is a competition designed to cover future cars that are environment-friendly. Mechanics of the competition include originality, safety, environmentalism and relevancy to Southern California’s ‘green’ lifestyle.

What if you were terminally ill and your doctor informed you that the venom from a snail could save your life?

What if the technology was available to produce a non-addictive painkiller that was thousands of times more potent than any morphine based product available today?

What if nanotechnology could provide the method of administering these potentially life-saving, pain elimination medicines within the near future? Would you be willing to support its advancement?

Well, nanotechnology is rapidly taking the “what if” out of just such medical conundrums. Biochemists, working in close liaison with nano-scientists, have discovered that the highly lethal venom contained in cone snails, which are found in coastal waters near coral reefs, can be extracted and, when administered via nanotechnologic methods, can potentially be used as a safe and effective alternative to highly addictive morphine-based medications.

Nanotechnology initiative programs are leading the highly competitive worldwide race in mining and providing a conduit for administering spiral snail toxins (known as conotoxins) and are developing methods of administering this peptide in a safe and positive manner.

Changes to the ion channels in human cells are directly responsible for a myriad of health disorders. Ion channels, which traditionally allow only calcium and potassium through their highly specific filtering system, can now be treated with toxins that have the ability to deactivate these channels. However, in the past, administration of these life altering conotoxins has offered a bit of a challenge to biology experts. That is, until now. This is where nanotechnology, with its innate ability to connect quantum dots, has provided a viable method of probing and infiltrating the cells in order to safely administer life altering drugs.

Due to its ability to specifically target finite and defined cells, nano-quantum dot technology provides the wherewithal to deliver conotoxins to targeted areas. Quantum dot, a nano-scale crystalline structure, is being investigated as a method of introducing medicine to specific areas of the body where the crystals act as probes that are able to track and report on antibodies, any viral activity, proteins in the area and even DNA composition.

By a system of imaging, this biochemistry and nanotechnology combination allows scientists and medical personnel alike to monitor the progression of the administered conotoxins within the body and allow the manipulation of toxin released at the designated sites.

Conotoxins have been proven as effective early detection and treatment methods for small cell lung cancer and for promoting anti-seizure treatment in epileptics. In addition, some success has been shown in treating patients who have suffered spinal cord injury, re-activating cells damaged due to oxygen deprivation and in treating clinical depression, irregular heart rhythms and some instances of urinary incontinence. Nanotechnology plays a vital role in the success of administering this innovative treatment by providing a safe and non-invasive method of administering treatment while reducing the risk of rejection by the body.

The possibility of advanced medical treatments when biochemistry, medicine and nanotechnology work in conjunction with one another is limitless.

Nanotechnology research has showed some promise in treatment of aging-related tissue degeneration in humans. With its in- vivo therapy, nanotechnology is credited with repairing degraded components of human DNA which significantly counterbalances and, in some cases, actually corrects the effects of common crippling age-related afflictions such as arthritis, osteoporosis and other debilitating diseases.

The 2009-2014 World Outlook for Nanotechnology

 

 This econometric study covers the world outlook for nanotechnology across more than 200 countries. For each year reported, estimates are given for the latent demand, or potential industry earnings (P.I.E.), for the country in question (in millions of U.S. dollars), the percent share the country is of the region and of the globe. These comparative benchmarks allow the reader to quickly gauge a country vis-à-vis others. Using econometric models which project fundamental economic dynamics within each country and across countries, latent demand estimates are created. This report does not discuss the specific players in the market serving the latent demand, nor specific details at the product level. The study also does not consider short-term cyclicalities that might affect realized sales. The study, therefore, is strategic in nature, taking an aggregate and long-run view, irrespective of the players or products involved. This study does not report actual sales data (which are simply unavailable, in a comparable or consistent manner in virtually all of the 230 countries of the world). This study gives, however, my estimates for the worldwide latent demand, or the P.I.E. for nanotechnology. It also shows how the P.I.E. is divided across the world’s regional and national markets. For each country, I also show my estimates of how the P.I.E. grows over time (positive or negative growth). In order to make these estimates, a multi-stage methodology was employed that is often taught in courses on international strategic planning at graduate schools of business. ( http://www.bharatbook.com/Market-Research-Reports/World-Outlook-for-Nanotechnology.html )

 

 WHAT IS LATENT DEMAND AND THE P.I.E.?

 

 The concept of latent demand is rather subtle. The term latent typically refers to something that is dormant, not observable or not yet realized. Demand is the notion of an economic quantity that a target population or market requires under different assumptions of price, quality, and distribution, among other factors. Latent demand, therefore, is commonly defined by economists as the industry earnings of a market when that market becomes accessible and attractive to serve by competing firms. It is a measure, therefore, of potential industry earnings (P.I.E.) or total revenues (not profit) if a market is served in an efficient manner. It is typically expressed as the total revenues potentially extracted by firms. The “market” is defined at a given level in the value chain. There can be latent demand at the retail level, at the wholesale level, the manufacturing level, and the raw materials level (the P.I.E. of higher levels of the value chain being always smaller than the P.I.E. of levels at lower levels of the same value chain, assuming all levels maintain minimum profitability).

 

 The latent demand for nanotechnology is not actual or historic sales. Nor is latent demand future sales. In fact, latent demand can be lower or higher than actual sales if a market is inefficient (i.e. not representative of relatively competitive levels). Inefficiencies arise from a number of factors, including the lack of international openness, cultural barriers to consumption, regulations, and cartel-like behavior on the part of firms. In general, however, latent demand is typically larger than actual sales in a country market. For reasons discussed later, this report does not consider the notion of “unit quantities”, only total latent revenues (i.e. a calculation of price times quantity is never made, though one is implied). The units used in this report are U.S. dollars not adjusted for inflation (i.e. the figures incorporate inflationary trends) and not adjusted for future dynamics in exchange rates. If inflation rates or exchange rates vary in a substantial way compared to recent experience, actually sales can also exceed latent demand (when expressed in U.S. dollars, not adjusted for inflation). On the other hand, latent demand can be typically higher than actual sales as there are often distribution inefficiencies that reduce actual sales below the level of latent demand.

sharmkan asked:


As we are facing the uncertainly in supply of crude oil, as well as affluent prices, other fuel source is a happening and hot topic. An interesting option could be ethanol, now made out of plants like corn and sugar cane. Companies and universities are eagerly working to grow this process of making ethanol from many other kinds of plant substance; that might considerably augment the amount of ethanol accessible as fuel. Nanotechnology might be to assist this important effort.

Presently ethanol that is used in fuel in the United States is made out of corn especially. The starch in the corn kernels is rehabilitated to sugar using enzymes. This starch is further fermented to shape up ethanol. Any how, in order to make a necessary reduction in the United States consummation of crude oil, we require up that production by a long way. The goal prepared recently by the United States government is to make 35 billion gallons of ethanol a year within the next ten years.

Researchers at Michigan State University are trying nanotechnology in a neat trick. They are heritably engineering corn to comprise the required enzyme. The plan is to make the enzyme unmoving until activated by high temperatures. When the cellulous part of the corn, like stalk, is procedures, the high giving out temperatures might set in motion the enzyme and change the cellulous to starch. This would avoid the added cost of creation the enzyme separately.

Researchers at the University of Rochester are as well studying how bacteria select an exacting enzyme, or enzymes, to break at specific kind of plant or other bio mass. They expect to make enzymes, which could change cellulous to ethanol in one step, other than the two steps used by the accessible processes. The advantage of cars that could be filled up with either fuel or ethanol has been verified in Brazil, they use much of its sugar cane crop to make ethanol. Using nanotechnology / genetic engineering to make ethanol from cellulous has the latent to make a serious dent in our use of crude oil. However we do require keeping an eye on some safety issues.

Tatiana Velitchkov asked:


Harnessing the power of tidal currents has the potential to provide unheard of clean, renewable energy production. Nanotechnology, with its innovative approach and non-surpassed success rate, may be the conduit needed to perfect the viability of ocean-current power as an alternative energy source.

Ocean currents are a natural phenomena located along most coastlines. The only requirement for harnessing their power is that the currents amalgamate under the surface of the ocean at depths of between eighty to two hundred and thirty feet (25 – 70 meters) with a flow of between five to ten feet per second. Harnessing this type of natural energy production it is not only a feasible undertaking, but is also quite an efficient way of supplying a clean, alternative energy source.

Although tidal power is an amazing concept, wave power also offers a much needed link to cheaper, cleaner power and its availability and conversion is being investigated vigorously in the ongoing race to market an economical, clean, renewable source of energy. Concerting above ground wind turbine units to meet undersea performance is technologically possible and, with a few adjustments, present day wind turbines are easily adapted to harness the awesome power of the sea.

Physicists have studied the gravitational pull of the moon and its effect on ocean currents for eons. Ocean tides are predictable, constant, natural occurrences that are easily forecasted for years in advance. This awesome and essentially untapped source of alternative power is not negatively affected either by adverse weather conditions or climate changes – which makes it ideal for further investigation and implementation.

In order to harness the full power of the ocean, nanotechnology may be just the ticket needed to successfully construct man-made tidal dams designed to control the flow as the tides ebb and recede. Predetermined openings would allow ocean currents to flow up through these gaps into a bay or estuary where the water is collected in the dam-like barrage and then released via a series of sluice gates and through a turbine which in turn generates electricity.

This alternative energy source is well established in La Rance France where a 240 megawatt facility has been operating since 1966. In addition, other, smaller sites have also garnered some success in Canada and in South Korea plans are underway to construct a plant larger than the one in France. However, there is one drawback to this type of power harnessing. Naturalists and environmentalists are concerned with the effects that constant flooding of the barrages has on the delicate ecosystems within the bays and estuaries where they are located.

Nanotechnology scientists are working in close liaison with forward thinking ecologists to correct this deficiency by designing a type of tidal lagoon to house the turbines. Instead of creating dams within the estuary itself, they propose to take advantage of strides in nanotechnology in order to erect man-made lagoons just off shore which would be built up from the seabed and reach out at least one meter above the high tide level. In this type of construction, the turbines would be situated in a wall close to, but not interfering with, the seabed itself. The concept is simple and very effective: the water would flow in through the turbine during high tide filling the lagoon, at low tide the flow would be reversed and the turbines turned in the opposite direction. The result is a generation of electricity in both directions four times a day. Careful placement of the lagoon would be determined by the differential between the maximum heights achievable between high and low tides. Producing energy by this means is anticipated to cost less than any coal fired facility, while protecting and encouraging a positive ecological environment.

Plans are underway to begin construction in several locations off the coast of Wales and China. This combination of conventional technology in partnership with nanotechnology advances has put environmental and ecological issues to rest, yet there is still a viable concern that this type of energy plant may have an adverse effect on shipping lanes. However, these concerns have also been considered and development of barrage ocean turbines that operate independently with little or no interference to ship traffic is well into production stages.

Because narrow passages promote the fastest movement of currents, the feasibility of harnessing huge amounts of power via ocean turbines offers an excellent alternative to nuclear and coal fired energy generating plants. With the reduced threat of ecosystem damage, advanced technology, co-operation between industry and environmental agencies and the almost unlimited locations that can potentially provide ideal conditions for tidal/ocean power harnessing, this type of energy source is generating serious attention worldwide.

Therefore, this begs the question: Is it really necessary to expose our planet and its people to constant ecological threat by continuing to provide nuclear power and its associated danger to the environment? The answer is, unequivocally – No. For those of us who care about living in a cleaner, safer world, it is imperative that we embrace nanotechnology assisted methods of energy generation which are proven to exceed present energy output while reducing the threat of pollution and destruction of our ecosystems.
