Conserve Energy with Nanotechnology Solar Panel

With the evident effects of environmental neglect, energy all over the world is becoming more and more depleted. With energy sources becoming scarce, it generally results to a stiff competition to obtain the limited sources for energy resulting to high power charges. There are several sources of energy, and some of them are even natural resources such as wind, solar, and hydro. But even if the sources of energy are natural resources and should be delivered to the people at a lower cost, still, power costs are high due to expenses incurred while generating electricity.

For several years now, scientists and researches has been looking at other means to obtain the following:

  • minimize generation costs of energy
  • provide energy to the people without causing any damages to the environment
  • generate renewable and recyclable energy resources
  • provide energy and electricity with the least possible charges
  • deliver electricity and energy to the public at the lowest possible cost

Achieving These Goals Using Nanotechnology Solar Panel

Nanotechnology aims to build important things with the use of tiny machines or by producing highly advanced, essential, and quality products using tools and techniques provided by nanotechnology.

Part of the researches being conducted is to come up with a solar panel that would accurately capture solar energy that can be utilized at home, in the office, and even in large-scale industrial areas. Although there are already solar panels available in the market today, these solar panels that are usually made of silicone panels only capture 67.4% light incident or solar energy emitted by the sun. Whereas, with nanotechnology, industrial and electrical manufacturers can now produce a coating for solar panels using nanorods that can capture 96.7 % light incident.

Nanorods used in nanotechnology solar panel looks like multi-layer funnels designed to capture light incident. The first layer absorbs the light that hits the panel at wide outer angles and turns it to a slightly narrower angle. The succeeding layers become narrower, like they are passing the light to the next layer even further as it funnels the light till it reaches the active region of the panel at a 90° angle. This process makes the solar panel securely capture the sun’s energy without having to rotate with the sun.

Benefits of Nanotechnology Solar Panel

Installing a nanorod on your solar panel can give out a lot of benefits not just for your personal advantages but to the whole of mankind. Some of these benefits include:

  • Lower solar power cost. The usual silicone solar panels available in the market today are placed at a single angle and can therefore absorb and generate lesser energy making the cost of solar power high. Nanotechnology solar power is designed to absorb the sunlight from any angle thus making generating more energy and making it available at a lesser cost.
  • Environment friendly. By patronizing renewable sources of energy such as energy coming from the sun, you would help in saving the world in your own little way. Solar power is also proven safe and does not emit hazardous waste.
  • Generating energy in a clean and green manner is, of course, just one element of a low carbon economy. Another element is the way in which energy is used and finding ways to reduce waste. In this area, home insulation is a very important factor – just think of how many poorly insulted homes there are in the world! A technology being developed to assist with insulating buildings use formaldehyde. The current tests are developing ways to coat ordinary doors and surfaces with the chemical to trap more air in, reducing heat transfer. This will be another breakthrough of the future.

Nanotechnology in Pharmaceutic Manufacturing

Imagine producing essential products such as medicines, fabric, glass, steel, and plastic materials for your home and office in almost in a blink of an eye. Or think about treating chronic and serious health conditions such as cancer, lupus, or even HIV thru a tiny device that can travel inside the human body and destroy the infected cells before they spread and cause debilitating damages to the body. You picture this: a tiny device, even smaller than an atom but can store massive information such as all the information contained in an international library. If you think that is quite impossible, then you probably haven’t heard about nanotechnology yet.

What Is Nanotechnology?

Nanotechnology used to be regarded in the fields of science as a science fiction: impossible and unattainable. But over time, nanotechnology and its uses among different facets of the society such as agriculture, home improvement, industrial, even in areas of environmental protection is already widely accepted and practiced. Nanotechnology in pharmaceutic manufacturing is also being done in big pharmaceutical and health companies. But what is nanotechnology? For people who are not in the fields of sciences and engineering, nanotechnology may be an unfamiliar word.

Nanotechnology is the engineering of functional systems at the molecular scale or thru tiny engineering. In essence, nanotechnology is the probability to build things from the bottom up using scientific techniques and tools that are currently developed today to come up with advanced, complete, and highly usable and essential products.

What Are the Benefits of Nanotechnology?

The basic benefit of nanotechnology is its ability to produce important products in a massive scale with the least or minimum cost. If managed properly, meaning, if the makers of products using nanotechnology would only make products that will provide benefit to mankind with utmost safety precautions in mind, nanotechnology is the next wave of industrial revolution. Nanotechnology will eliminate production costs for materials, labor, and energy because it can produce bigger and better things invented by our forefathers at a staggering speed and amazing precision there is no room for mistakes.

How Can Nanotechnology Be Applied to Pharmaceutic Manufacturing?

Man is exposed to varied health hazards these days due to the advent of science and technology that most often emit hazardous free radicals and pollutants that contribute to the general decline of mankind. Because of this and also because of man’s increasingly sedentary lifestyle, people need more medication for varied diseases. Millions of people are in need of medication and medical maintenance that is why pharmaceutical companies is a booming business.

If nanotechnology in pharmaceutic manufacturing would be applied, with the speedy production of quality medicines at a very minimal cost, it will cause economic and social ripples that could be beneficial to mankind. Because of very low production cost, manufacturing companies would be compelled to lower down the prices of medicines. Nanotechnology in pharmaceutic manufacturing would be beneficial not just to end consumers of the medicines but also to the pharmaceurical companies or drug makers because they would be able to produce quality and highly marketable drugs with the least capital and generation cost needed.

Nanotechnology in Cars: Drive of the Future

Cars are common expressions of how developed a nation is. True to this statement, the most developed nations of the world have their own and stable car manufacturing industries that they export to the rest of the world, earning revenues for the source country. More than that, some nations have become synonymous with the brand and quality of their manufactured cars as the case of Japan, Germany, and the United States. Unsatisfied with this and all the modifications they have created on their cars, they have taken automotive technology a bit further by using nanotechnology for cars.

When nanotechnology was discovered, the automotive industry was not seen as a possible beneficiary from this piece of knowledge. Yet in time, the automotive industry became one of the heaviest users of nanotech. With nanotechnology in cars, vehicles were made more efficient.

The Application of Nanotechnology in Cars

The following are some of the most common examples of the application of nanotechnology in cars:

  • Engine and transmission systems. In contemporary cars, a large share of the vehicle’s weight is due to the weight of the engine and the transmission system of the vehicle. As a result, cars are fuel-hungry because of the need to push forward such a heavy machine. Nonetheless, with the advent of alloys, engines were made lighter somewhat but not sufficient to make them fuel-efficient. The answer came with the arrival of nanotechnology. With nanotechnology, engines and parts were made a lot lighter, thus eliminating the need to consume more fuel just to power the vehicle forward.

  • Chassis. In the same manner that the engine and its parts were made lighter, the same benefit happened in the case of the chassis. Aside from being lighter, chassis and engines were also made more durable, making them withstand daily workload on the road.
  • One of the most advanced examples of nanotechnology in cars involves the production of paint that is constituted in microvolumes. The idea is to create a surface that automatically heals itself whenever it is scratched or tainted with some foreign mark. This procedure allows for the paint to release nano paint particles that automatically spreads to cover up the scratched area. It works instantly you’ll hardy notice the surface was scratched at some point.
  • Another of the advanced applications of nanotechnology for cars involves the production of mirrors and side panels that are made out of nano particles. Being so, they filter the rays of the sun, smoke, and other pollutants in the atmosphere. The same technology allows radio and phone signals as well as sound waves to freely enter the cars so that the occupants of the vehicle will not be made oblivious to the world outside. This is beneficial for those who have some form of hearing defects; even with all the windows closed, you may still be able to hear the honking of the horn of the next car. Likewise, you do not have to open the window when it is raining just to get a clear signal when calling from your mobile phone.

Safety Concerns with Nanotechnology: Knowing the Risks and Benefits

Nanotechnology is one of the hottest scientific discoveries of the present times. This is because nanotechnology presents a lot of promise that all other treatment methodologies before it were unable to deliver. Moreover, nanotechnology also saw applications in other areas aside from the fields it was intended for. As a result, the fields of applications of nanotechnology are as varied as the possible risks that come with it. As such, safety concerns with nanotechnology aired by ordinary citizens and experts alike must not be ignored because it is one of the ways to make the technology very safe for anyone using them.

Common Concerns with Nanotechnology

The following are some of the most common concerns expressed by people on the use of nanotechnology:

  • Nanotechnology is a new scientific application. Although this can also mean to be a benefit for mankind, there are safety concerns related to its applications mainly because of the fact that it is something that is not yet fully tested. One of the safety concerns with nanotechnology in this field involves the application of the technology in medical and health fields. Some are afraid that they might trigger harmful effects instead of the intended beneficial effects.

  • Because nanotechnology involves the manipulation of matter at the atomic and molecular levels, there are fears that such manipulation may result to the production of materials that will radically alter man’s way of life. This is seen especially to be dangerous in the field of medical applications where nano particles are used in various ways such as sunscreen and injectable medications. Safety concerns with nanotechnology in these areas are heightened because such manipulation of matter may trigger the body to react in a negative way to the presence of nanotechnology products.
  • There are also fears that the environment may be placed in jeopardy that nanotechnology products may increase the pollution level in many areas at a time when the need for environmental conservation is vigorously pursued everywhere. For example, the production of better engines for automotives and windows for cars may prompt car manufacturers and local dealers to wantonly discard these parts that can possibly cause environmental nightmare with the absence of better programs on waste disposal. An interesting twist here is nanotechnology is a thriving business in the United States, amounting to billions of dollars. However, despite all these income, very little thought is spared for health and environmental concerns. Because nano particles are very small, they are very difficult to degrade and may easily pass on from one person to another, in the process becoming agents of ailments.
  • Another of the numerous safety concerns with nanotechnology is the lack of a centralized monitoring agency that will see to it that all endeavors in this field are religiously monitored. As a proof of this, there are very little journals and researches on the safety concerns with nanotechnology that inevitably enhances the fears that people may have on this technological applications and advancements.
