Pentagonal Moleculs nanomaterials

In recent times has begun to think not so much in the materials used for the production of solar panels, but rather in its design, using from the striking form of Swiss cheese, until new eye-catching designs that seek to achieve greater energy efficiency without thinking of a high cost of production.

Another example of this is the work presented by researchers at the University of Cambridge who are developing nano materials that could even assemble itself by establishing solar thin plate panels (technology in mouths of all these days) and applicable to electronic devices with smaller dimensions to the current.
Design leads to create molecules with pentagonal symmetry which can relocate randomly using a substrate of copper, which gives rise to thin plates of a very high stability, which could be used in future in creating from processors for computers to other types of circuits, as a photovoltaic solar panel.
In addition to providing a very good energy efficiency, they also have the advantage of requiring the use of very little material, cheaper costs and offering the same amount of energy.

Environmental Contamination Poisoned Air

Until the industrial revolution, the purity of the single atmosphere was altered by natural causes, such as for example the volcanic eruptions, but currently, the activity of man is to the atmosphere as a huge volcano not to introduce new substances in the air, making not only pollution but other dangerous evils as the rain.



Also, there is a big difference between gas eruptions and the chimneys and exhaust pipes. The latter release substances often strange, which react between if and natural atmospheric components, causing this, serious disturbances.
The massive introduction of pollutants alter the composition of the atmosphere and seriously damages human health , climate stability, and development of ecosystems, causing damage to the planet that are much more than a generation or a hundred years.

Saving Energy With Programmable Thermostats

Winter and summer are the seasons where more energy is consumed, given that the heating and air conditioning are often increased use. With programmable thermostats installed in the home can be achieved an energy saving more than notable.





With thermostats can program that will condition the temperature at certain times, saving up to 55% of the energy if it is used properly, and this saving will not affect our comfort.
These thermostats can be set to cool environments during the night while you sleep and morning turns off, or in the summer to maintain the air conditioning turned off while we are not at home, and turn towards the hour in which we would be returning.
There are many different models, and some allow us programme several times a day.

Top 5 Advantages Of Using Renewable Alternative Energy Sources

Until a few years back, the use of renewable alternative energy was not too well known. With time, such as the danger of exhausting fossil fuels became a reality, science discovered the use of renewable alternative energy as en excellent way to fuel the energy needs of humanity. As a result, you can observe the use of solar energy, wind energy, water energy, and so on, powering the energy needs.

All this does not come with its benefits bound. The best deal with renewable alternative energy is that you many ways and methods of processing power.

Here are the top 5 advantages of using renewable alternative energy

Solid waste disposal-every household delivers its share of household waste. By this household waste to generate energy to process, could you provide a great environment. By doing this, you ensure a clean environment and the double advantage of generating energy from waste tyres.

These energy sources would never exhaust unlike coal, gasoline and oil that is known with time, get exhausted alternative energy sources would never run out of stock. For example, the chance of losing its warmth, Sun is extremely low. Local production means energy at lower prices and developments in some countries could the fortunes of gasoline and oil prices, price changes due to uncontrollable factors change is minimized with alternative energy methods. Can an energy through this method, local, which means that energy prices would now no longer have to depend on global conditions generate.

Domestic demand meets domestic delivery-a society, for example, 100 MW of excess power. In order to meet demand this power, the society their city government to provide them with surplus power. Alternatively, they could a solar power generator set and work on self-providing energy. A clean future for mankind-the fact that fossil fuels when burned or used, let toxic and poisonous gases such as carbon monoxide, lead Oxide, and so on means they would not be ideal for use, particularly in the longer term. The good news is that with alternative energy, you wouldn't need such a disadvantage.

Out of every 4 people, 2 thinking of using renewable energy for the needs of their energy and strength. This is indeed a good enough transition in the minds of people, but given the increased emphasis on global warming and pollution by greenhouse gases, this percentage can only be seen up.

Buenos Aires: in search of a renewable and sustainable public transport.

The City of Buenos Aires is one of the largest Latin America and like so many others of them, starts showing the first signs of a sustainable public transport planning. In spite of the existing delay this same problem in Europe and elsewhere in the world, the capital of Argentina gives his first steps with the construction of Metrobus (a Bus rapid transit system) to be added to the previous programmes of buses hybrids, bicisendas and bike relay.

Buenos Aires City Government announced the construction of its first line of Metrobus, which will take a walk West across much of the Federal Capital. While the service will be provided by bus lines current (i.e. buses conventional), efficiency of this system will involve a reduction of the transit significant (50% less buses on the same route) thus saving fuel and greenhouse gas emissions.

While it starts up this project of Metrobus, it is already working for some months the first hybrid bus of the City and the production of new units that could begin to serve this year being taken forward.

British Military Solar Energy

One of the best ways to expand the acceptance of solar energy in different devices is the diffusion of new technologies of various applications, something which has been in the last few days with the emergence of a hybrid generator, and now with something that is applied to the uniform of every soldier.

There are many devices that are used by a soldier in hostile lands, many of them require electricity to operate, and obviously, the most used are stacks of fuel either rechargeable batteries long term creating discomfort, because they tend to be quite heavy.
As a way to lighten the gait of the British infantry, it was decided to opt for this form of renewable energy, in replacement of the fuel cell and using a thermoelectric system that takes advantage of the photovoltaic solar energy to feed different devices, from flashlights to those used for various operations military.
This system, developed by researchers at the University of Glasgow, has been combined to a thermoelectric system with energy storage for a wide variety of applications, taking advantage of its low weight and high portability (can be in backpacks or integrated into the uniform)

The Cremation Of Trash Problems

Today the accumulation of garbage is still a significant, causing various types of pollution problem and that it plans to persist. One of the methods used for their disposal is incineration plants, but actually cause worse evils to the environment.

The incineration of waste does not mean their elimination, but his transformation in ashes and gases whose effect on the environment is much more toxic than the products in its solid state.

While many incinerators have systems to filter and wash the fumes, none is fully effective and they are far from it.

It must be borne in mind that a plant with 99.99% efficiency expels the atmosphere several tons of toxic waste per year.

Among those eliminated gases have been detected toxic metals, lead, mercury and cadmium, and so hazardous products such as PCBs and dioxins, substances that accumulate in the fatty tissues and are highly carcinogenic.

Renewable Energy in Bridges

A new trend is the designing bridges that - in addition to serving as a communication between two places - generate energy from renewable sources. They are called bridges of power generation (energy generating bridges). There are solar energy, such as the Brisbane and also wind. No doubt they are the future in the field of bridges.

Building bridges capable of adding to the production of energy is without a doubt advantageous. Mainly because it involves a large cost saving and space savings. You have these bridges of power generation from renewable sources largely allows to minimize the loss of land involving other types of projects, that both structures are combined into a single.
The bridges are also excellent for the generation of renewable energy because of his height. Being located at one height greater, are usually exposed to winds which easily can be used to produce energy. They also receive a lot of sunlight.
Even though many of them are still a promise, it's worth taking a look at these innovative designs:
1 London

In this design of cherry chetwood, London Bridge not only generate renewable energy, but they also produce organic as a vertical farm food.
2 Seoul

The Bridge will be capable of generating electricity from the numerous photovoltaic solar panels installed on it. The electricity generated will be used for feeding of various facilities in the city and the bridge itself, such as a library, a Museum and a shopping center of IT. The bridge also has docks to act as a parking lot for boats.
3 Lisbon

This Bridge helps to generate wind energy through a network of 2,188 light panels that rotate with the wind. It will be built entirely in recycled steel and its design is based on a system of beams which helps to increase the speed of the wind on the bridge.

Plate Solar Silicon In The Form of Swiss Cheese

Development of photovoltaic solar energy points in large part to the semiconductor material that is capable of converting solar radiation where the cells in thin plate are profiled as replacements to the current in electric power, and even more so the polymer solar cells, although there are also other malleable materials such as silicone, which continue to provide good results.

In this last variant, it is experimenting with modifying designs, because the physico-chemical properties vary according to the disposition of the molecules, and thus a greater conductivity can be gained in those who offer more free electrons.

Developed by the Academy of Sciences of Czech Republic, in conjunction with Swiss oerlikon Solar, is has recently proposed the creation of photovoltaic cells in thin plate using silicone not the distributing as regular, but rather seeks to imitate a honeycomb, or as they have called you, a Swiss cheese.

In this way insterticios are left between the material used, with a substrate derived from Zinc oxide, amorphous panels of lesser thickness, markedly favouring the conductivity and energy efficiency.

United States Wind Power

Today we bring you some pretty illustrative statistics on how much has grown United States wind power. A report from the Department of energy has announced the figures of wind energy in 2010. Within the total capacity of power generation added in the course of this year, within which this renewable had 25%.

This can be read in different ways. On the one hand, the amount of new wind energy capacity over the total decreased for previous years: 25% in 2010, when he came from 42% in 2009 and 43% in 2008. That is quite negative, especially because coal has grown significantly in the last session.

On the other hand should be one no minor detail: the impact of the economic recession of 2008-2009. The growth in the period 2008-2009 for wind power is explained in this context of crisis by the fact that had started to manage in previous years. Now, on the other hand is evident which are very few projects that were initiated during the crisis, with only 5 openings this year.

Power Hydraulics

Since very ancient times seen as mobility flows of water can be very useful in obtaining energy, to push the aspas mill, as he later obtain electricity through the movement of turbines in the so-called power plants, with wonderful construction of dams.

Named as Power hydraulics, and through physical concepts, is the transformation of Kinetic energy and the Energy potential are obtained from the current water or jumps of water either the accumulation of water by dams and the subsequent release of a minimal part, whose current makes move the turbines are directly connected to a generator of electric power.

The main advantage we must consider is that this is a clean energy, renewable, and that it does not generate a greater environmental impact, especially in those regions where orographic conditions are favourable to the construction of a dam, especially where there is a wealth of desniveles in the rivers or are usually frequent rains.

Economic benefits: although they require a high initial investment for the construction of dams, represent a long-term a considerable economic saving compared those power plants which operate by burning fossil fuels, which results in need of imports for its operation.

Dams have a lifespan that can reach up to 100 years, plus their maintenance is practically bajoNo require much staff employment as most of its operation is automatic and is given in the form naturalEn function does not produce carbon dioxide. Yes they do so at the time of its construction, although the amount is very low.

The main advantage, and one of the most criticised, is that if the measures are not taken, can be generated a strong destruction of aquatic ecosystems, something that is neglected to build them, especially design, resulting as a sort of trap for fish.Rivers, erosion caused because the outgoing water dams (which has served to move the turbines) does not contain sediments and thus mobilizes eroding the margins.The alteration of rivers caused by a bad creation of reservoirs can result in flooding in populations adjoining that could even make losing land fertile.

Solar Panels To The Sun

The Sun is one of the most abundant energy that we have sources, the difficult point is to find ways to use it efficiently. Pursuing this, researchers of Smart Solar international in Tokyo, Japan, have designed a solar panel which has a system to track the Sun as it moves in his tour diary.

The basic component of this new device, is a series of aluminum mirror bar rotating, according to the Sun as it moves across the sky. These mirrors reflect light on a central tube, containing several layers high performance solar cells . Their construction requires a number of much less than the of the photovoltaic panels most common silicon.

By its design features, to avoid overheating also has a device that derives from the excess heat to heat water, giving an additional benefit.

According to its creators, this type of solar panels is capable of producing twice the power than other existing systems. This promise will be able to see her promptly fulfilled as they hope to launch in October in Japan, which is expected to help provide renewable energy to those affected by the tsunami.

Photovoltaic chemotherapy medicine

As many know, the most commonly used for diseases autoimmune type and more than anything else in cancer, treatment is chemotherapy, but of course, has its negative side relating mainly the hair loss, passing by nausea, vomiting, and even loss of appetite, as a result of the toxic treatment effect.

A group of students from the University of Texas at El Paso (United States) is working on a modification to the treatment of chemotherapy that employs a renewable source of energy, improving the living conditions of those who suffer from cancer and significantly reducing toxic levels.

Today, the chemotherapy drugs are entered into the bloodstream where they travel by different bodies until finally contact with the target being patients systematically with side effects mentioned above, usually caused by not being able to "sharpen" these drugs to the tumour tissue.

This project, currently in phase of analysis, uses small photovoltaic panels that will allow free drugs only into the tumour, tissue contact activating using an infrared light or laser, which are able to traverse tissues in a depth of up to 10 centimeters.

Taken from a renewable energy source, this amendment will change the treatment of chemotherapy and it significantly the negative effects of treatment, so expect a full success in its development (currently in testing phase)

Purifying Water With Solar Energy

In addition to requiring a very low maintenance, the benefits of using solar energy not only result in a lower CO2 emissions compared to electric power with the burning of fossil fuels, but it can also lead to a lot of uses.

Students at University of Buenos Aires (Argentina) have recently submitted a team Water Purifier that has been thought for those places where is no access to drinking water, especially in rural areas where even don't have access to the electricity grid.

This team is a relatively low cost and requires virtually no maintenance, which further facilitates the task using a derivation of thermal solar energy to make a double distillation of water, and can not only remove heavy metals and other toxic, but also the germs.

Basically, the water passes through a system of pipes which receives a double distillation, interacting with a fluid circuit that transmits the necessary heat and utilization of titanium dioxide to eliminate any trace of germs by a reaction catalytic.

This is added the inclusion of a polymer that allows the passage of ultraviolet light into the water, allowing the irradiation.
