White House Issues Apology By Jaczko



Chief of Staff Bill Daley breaks White House silence over escalating conflicts about the NRC



The shouting may be over in the long simmering dispute that broke out into the open last Friday at the U.S. Nuclear Regulatory Commission. NRC Chairman Gregory Jaczko has issued an apology via the White House to the other four commissioners who jointly signed a letter complaining about his management practices.

A hearing by the House Oversight Committee scheduled for Wednesday December 14 will not see the fireworks that were expected as a result of the heated accusations that were exchanged today between committee chair Darrell Issa (R-Calif) and Rep. Ed Markey (D-Mass) on the MSNBC TV network. Their verbal fireworks threatened to derail any effort to contain the conflict.

Now, it is more likely that the hearing will include acts of contrition and pledges for better communication among the five commissioners. Skeptics think it won't last much longer than the late night news coverage, but stranger things have happened in DC. The good news is there are no allegations of financial wrong doing and no got drunk and jumped in the reflecting pool with a stripper.

Daley said in his letter that he believes the sources of the conflict can be addressed and he emphasized that while this is taking place that there will be no compromise of safety at the nation's 104 nuclear reactors.

Rep. Issa is not convinced that an olive branch has been extended by Jaczko or the White House. He said in a statement released late Monday evening that "the White House is in denial" about the serious nature of infighting at the NRC.

White House wakes up and smells the coffee


These late breaking events follow an action packed Monday of meetings in which Daley and other White House staff worked to stave off a major meltdown of the regulatory agency.

According to press reports about Daley's letter to Issa, Jaczko has issued a personal apology and will seek third party mediation to help work out the differences that have emerged between him and the other four commissioners.


"The chairman apologized for the distractions caused by the present tensions and has taken responsibility for improving communications among the commissioners," Daley wrote.

Daley also wrote, "We have concluded that while there are tensions and disagreements among the commissioners, these management differences have not impaired the commission's ability to fulfill its mission"

From that formal language it appears that the White House counsel is in the picture reminding the President what happens to the nation's electricity supply if the NRC is determined to be non compos mentis. Based on the letter the four commissioners sent on October 13, all five have had plenty of reasons to be distracted even if they also contributed to the fray by responding to perceived as well as real provocation. Now, the White House says, it is time for the nonsense to stop.

A white dove flies over troubled waters

The White House had little choice but to get Jaczko to make a peace offering while also backing him in the position. Many who have rankled, with some justification, at Jaczko's erratic tenure at the NRC feel this may be a time when he might be forced to leave the agency or to step down as chairman. Neither is likely to happen as replacing him would be politically difficult.

But once his disputes went public, he became a liability, but not for the reasons that ordinarily come to mind. In terms of realist politics, Jaczko was given the job for one reason, and that was to bottle up the Yucca Mountain project by preventing the license application from ever getting a hearing.

In the world of political appointments in Washington, DC, when people get mission focused tasks like that, they are supposed to do their job, and then keep their head down on all other matters.

Jaczko became a liability because he disregarded this salient piece of advice getting into a high profile series of ego driven personality conflicts with the other commissioners. Again, from the point of view of realist politics, it was an unwise series of moves that could mark the rest of his career because he blew up the one reason he was useful to the Obama White House.

Who's the real opponent of Yucca Mountain?

Sen. Harry Reid has long been tagged as the point man for opposition to Yucca Mountain. In point of fact, he was a very convenient point man too giving the Obama campaign in 2008 a made to order wedge issue to win Nevada electoral votes,

It was the President who appointed Jaczko to the NRC and the fact that he came from Reid's staff is simply the mechanics of DC politics.

While Jaczko had previously worked for anti-nuke arch druid Rep. Ed Markey, that probably didn't matter to the wonkish Obama White House which may have been more impressed with his Ph.D. in physics from a top university.

The president needs to win Nevada again in 2012, and he needs Yucca to remain dead dead dead. But Jaczko made himself a target by pestering the other four commissioners over penny ante stuff like travel, staff assignments, and an unpleasant management style. Of course the iceberg that was 7/8ths under water was the dispute over the Yucca Mountain license. You wouldn't know it from the newspaper headlines.

The White House got an apology from Jaczko because he was no longer following the mandate of do one thing, do it well, and don't make waves on anything else.

The four commissioners shouldn't take the apology personally for the simple reason it isn't about them. Jaczko's mea culpa is to the White House and Congress over forgetting why he got the job.

Jaczko is smart guy, but the train of events indicates that that he might have outsmarted himself. It's a hard lesson to learn. Maybe now the NRC can get back to work.

Use the power of the Sun as a source of alternative energy and save

Getting the world to shift away from fossil fuels to alternative energy sources whenever and wherever possible is the reason for this article because i really believe in a better tomorrow with a cleaner planet for everyone to enjoy.

Having crystal clear water to drink fresh from any source anywhere without having to clean it with chemicals and processes and fresh clean air to breath without any co2's or diesel fuel emission or any other chemicals in it which makes up the soup we breath today - should be our rights. With all the natural disasters like floods and hurricanes and the continually changing weather patterns should be enough to make everyone think seriously of using alternate green sources of energy to supply energy needs.

So, that being said i think everyone should try to convert totally or at least half of all their energy needs from gas / coal or electricity ( from electrical plants ) to alternative clean energy sources - be it wind power, solar power or zero point power which is made using magnets or even wave and tidal power. Lead by example and people will follow. I myself own an adult electric tricycle and i use it for all my intercity trips ( shopping / visiting ), it saves me on gas and works even in the winter. I get compliments all the time for how cool it is and let me say just about everybody wants one.

Solar Power Your Life

Did you know that harnessing and converting the energy coming from our Sun as a source is one of the coolest and most talked about ways for producing alternative energy these days? Using solar panels to gather the heat rays from the Sun and then convert them into electricity is just starting to catch on and you can learn to use it to power your lights in your home or instead of gas to heat your home. You can also convert your car to electricity and just plug it in to recharge it at your own house for next to nothing. Hey business owners you can power your business with solar power too. The best thing about converting your home and business to solar power is that it can and will be able to take care of all of everyone's energy needs far into the future at a fraction of the cost of purchasing from electrical retailers and will only create a fraction of the pollutants.

In researching which alternative energy source to use you will want to make sure that you seriously take solar power into consideration by learning all the advantages this alternative power source has to offer, it would well be worth your time and effort to do the research before starting any project.

Money Concerns Will Make You Take Solar Power Seriously

Pretty soon everyone will have to start taking solar power seriously anyway because purchasing electricity from retailers is going to start taking up more and more of peoples disposable incomes and soon will become to expensive for the average family and it's up to you to lead the way and convert your home to a clean alternate energy source and to make sure all of the others in your family get into thinking how to save energy and use it more wisely while they're still young and impressionable. Try making up games to play together for brainstorming ideas on how to save energy. Here's a couple of ideas to start off with - 1 - sell off a TV set so the family can gather in one room to watch TV together instead of separately on different sets, just doing this can save some money and bring your family back together as a loving family unit for a result and - 2 - convert you car to electricity and save on transportation costs and at the same time you will be helping to save the environment too.

Modern Times Call for Modern Thinking

It is the modern times and there are modern ways to approach things like electricity and transportation. You really should want to help the world to clean the atmosphere that we have been destroying for a hundred years by making sure the energy sources and any way we use them give off fewer pollutants and help preserve and possibly rejuvenate the Earth for future generations.

I'll bet that you and others you know use solar power and don't even know it. I'm sure someone you know owns a swimming pool, well,the blanket they put over it when nobody is using it is called a solar blanket which is a crude but is still an effective type of solar energy. The solar blanket helps harness the suns warmth and then transfers it to the water keeping the pool at a more palatable temperature. This way you don't need to use a direct heating source to keep your pool comfortably heated and this saves you money not having to use electricity to do this job for you. Surely this is not same way of collecting the Sun's power and converting it into easy to use electricity, however it is the idea that started the ball rolling on solar energy.

Solar - The Way To Go

The Sun has enough energy to power yours and everyone's lives on the planet with ease. Everybody needs to learn how to efficiently capture the Sun's energy by using solar panels, saving money and the planet as a spin-off benefit. Solar panels were designed for us to do just this.

The initial outlay for purchasing your own solar power generation system to power every aspect of your life can range anywhere from 10-25 thousand dollars depending on your lifestyle, however you can recuperate your costs within an average of 5-15 years through savings on electricity bills and if you enlarge your system so you make extra power you then sell to the electric suppliers break-even time will be shortened again.

Something you may not have thought of is that you can reduce your start-up and repair costs considerably by learning to do it all by yourself.

Nowadays it's easy to find solar panels at your local solar power retailer outlet but to save some money you should learn to build and install your own solar system. Adding enough panels to your project to totally convert your home to solar power and run all the appliances within is easily figured out and you may even add a couple extra panels to have a little left over energy to sell back to the power companies and pocket some profits. New and more efficient products are being developed every day to help you achieve this.

I must say this again - it is very important that you consider solar power and all that this technology can offer for the building or remodeling of a home or business so make sure to do the research and learn about it. Just imagine no more blackouts or problems with your outdoor lighting or security because the power is out. There is a never-ending list of uses for solar power and the sooner we convert the easier it will be for everyone to breathe easy again too.

Zero carbon emissions when using solar power

And when it comes to using solar power there are zero carbon emissions which today is what is ruining our environment, and with solar power there isn't any major pollution that you need to worry about. Only the batteries you use would fall into this category and if you just make sure to dispose of your used up batteries through a proper government-run disposal service you can be sure they know what they are doing and will dispose of it properly and in an environmentally friendly manner. All that you need to do is to be sure to extend the life of your batteries by keeping your batteries charged at all times and don't leave batteries under charged because this leads to lead sulfates accumulating and reducing the storage capacity of batteries.

Another thing is try to keep your battery cool and if at all possible try not placing it in a hot area like under the hood of your car. If you must do this place a heat shield over it to protect it from the heat that's under the hood of your car - excessive heat can reduce the life span of battery by 6-8 months. There are many different types of batteries and different little things you can do to extend their life. Like on a cell phone you can turn down the screen brightness to save on energy and recharging cycles (the less you need to recharge a battery the longer it will last). And when your batteries just don't perform as they should anymore another option you have is to recycle or recondition the batteries yourself. There are guides to teach you to do this and it's not as hard as you think.

Wind Power is Good But...

Don't get me wrong wind power will work fine but the maintenance of a wind turbine is a little costly because moving parts just seem to break more often and the windmill blades sometimes get bent in big storms leaving you scrambling to fix it, whereas solar panels require basically no maintenance but will incur replacement costs if one fails (try to keep a spare panel handy for just such an instance). But if you live in a place where light from the Sun is a little scarce then wind power generation is another way to go green and save, it's just a little more work.

An Inexhaustible Energy Source

The Sun is one energy source that we are going to be able to exploit for thousands of years to come. It is going to be there even when all other sources have become unavailable. You will find that there is a lot of solar-powered research being done today and it is the most promising future power source at the moment,who knows what the far future may bring.

However the future is happening now just look around and you will see all the solar-powered vehicles, lights, houses, offices and so much more. Actually go outside now and take a walk around your neighborhood and see all people who already use solar power these ways, just look for the solar panels outside a home or business or even the outside solar lights people use to light up their property and you know they are doing their part to save the environment, are you?

If you live in a hot and sunny climate you will find that solar panels are going to be the most efficient alternative power source for you, and the more sun your area receives the better it is for recharging you're system to full capacity everyday.

Do It All Yourself

Don't forget there are guides you can purchase to teach you how to build and set up your own system. These guides will help you learn to do this and are a good way that you can learn something which will save you money and will even help you put some away for a rainy day if you want. If you construct your own solar panels and do all the system set up yourself you can save thousands over paying an installer to do the work for you and that money will now stay in your pocket and now you won't have to pay the big electricity retail giants anything for their power because you will be enjoying the pride and joy of being self-sufficient when your finished.

On a Personal Note

I feel using any of the alternative green sources of energy generation is our duty to help alleviate the stress on all the coal-fired power plants and to save some hard-earned cash. If enough people switch their home energy source to solar maybe we could shut down some of them coal-fired electrical generation plants and be able to breath easier.

It's also my opinion that governments should retrofit all existing houses with solar panels and / or wind turbines to meet everyone's personal needs. Making repairs tax exempt and / or tax-deductible would help people pay for their own repairs and as a result everyone would live better and most of all more self-sufficient.

Businesses should have to retrofit their own businesses but the same tax exempt and / or tax-deductible offer should be given for repairs.

Purchasing a clean alternative energy should not cost a pound of flesh either, especially in cold climates where energy is needed to keep you warm and ALIVE. Governments must be made to understand this and quit giving approval for insane energy rate hikes year in and year out.

Keep an open mind and you will see that the new ways of producing clean green power has enough benefits to convince you to convert your life and believe me - you won't be disappointed.

Water scarcity: reality or speech


Porto-Gonçalves in the problem analysis of the lack of water is really very interesting. In this first article we will concentrate only on one of the points that works how real is the concept of the "water scarcity".

Of all I recommend to read the full text of water does not deny to anyone, since it has no waste for whom we are concerned about such issues.






Porto-Gonçalves in the problem analysis of the lack of water is really very interesting. In this first article we will concentrate only on one of the points that works how real is the concept of the "water scarcity".

Of all I recommend to read the full text of water does not deny to anyone, since it has no waste for whom we are concerned about such issues.



Since the beginning the author tells us that there is a "speech of scarcity", and here, using the word "he remarks" marks clearly its position that this is a deliberate message and not a simple and innocent description of reality. And this founded it with figures who come to demonstrate that the situation is not as alarming as it seeks us to show.

As he tells Porto-Gonçalves, information circulating most commonly on the "stock" of drinking water as follows:

Planet Earth has 3/4 parts of water. Of this, 97% are the oceans and seas, which is why this water to salt, is not suitable for human consumption. Then is 3% of fresh water, but 2/3 of it are in solid state because they are ice and polar ice caps, ergo, are not available for human consumption at the end of the equation the result is that less than 1% of the total water on our planet would be safe.

This is the brief outline of the discourse from scarcity. And as brilliantly defines the author, it is "made" so that, in the end, the reader is already thirsty. There warns Porto-Gonçalves that we should not give by scientific any mere statistics because - as he says - there are a number of basic errors from the own scientific point of view in these numbers.

If these numbers are not entirely accurate, is because there are others factors were missing in the equation. And what we need to take into account is mainly that the fresh water on Earth is largely provided by the water cycle. And mostly as a result of evaporation from the oceans and seas.


Let's look at some data provides in this regard:

Approximately 505.000 Km3 evaporates each year of the oceans and seas (this is equivalent to a layer 1.4 metres thick on the surface of seas and oceans). Although these sources of water salt, salt is not transmitted in evaporation. Of these 505.000 Km3 80% returns to precipitate on the oceans and seas, but the remaining 20% drop over the continental surface. And the rains that fall on all continents, about 3/4 parts evaporate from lakes, ponds, rivers, soil and plants (evapotranspiration). It is 1/4 remaining drain to the sea again.


This cycle and these levels remain valid according to evidence from the last ice age. In other words, the amount of water available has not changed significant since at least 12,000 to 18,000 years ago.

Moreover, the amount of water available not only not declined but may even be increasing as a result of the melting of the polar ice caps and glaciers due to global warming. Although it sounds like a paradoja…

The question then seems to be that drinking water is not scarce at the global level. And however, according to UN reports nearly 3 billion people have no access to it. That leaves us thinking that the question to ask is not "does there is enough water for all?", but "who controls her?, and what uses it?".

Top 5 Benefits of Using Renewable Alternative Energy

Until some years back, the use of renewable alternative energy wasn't too well known. With time, 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 mankind. As a result, you can observe the use of solar energy, wind energy, water energy and so on, powering the energy needs.


All of this doesn't come with its benefits tied in. The best deal with renewable alternative energy is that you have many ways and methods of processing energy.


Here are the 5 top benefits of using renewable alternative energy


Elimination of solid waste - Every household delivers its share of household waste. By processing this household waste to generate energy, you could take care of a major environmental concern. By doing this, you ensure a clean environment and the dual benefit of generating energy from waste materials also ties in. These energy sources would never exhaust - Unlike coal, petrol and oil which are known to get exhausted with time, alternative energy sources would never run out of stock. For example, the odds of sun losing its heat, is extremely low.


Local production means energy at lower prices - If the developments in some countries could change the fortunes of petrol and oil prices, price changes due to uncontrollable factors is minimized with alternative energy methods. One can generate energy through this method, locally, which means the energy prices would now no longer have to depend on global conditions. Domestic demand meets domestic supply - For example, a society needs 100 MW of surplus power. To meet this power demand, the society could ask their city administration to provide them with surplus power. Alternatively, they could set up a solar power generator and work on self-providing energy. A clean future for mankind - The fact that fossil fuels when burnt or used, release toxic and poisonous gases like Carbon Monoxide, Lead Oxide and so on means they wouldn't be ideal for use, especially in the longer run. The good news is that with alternative energy, you wouldn't have to encounter any such disadvantage.


Out of every 4 individuals, 2 think of using renewable sources of energy for their energy and power needs. This indeed is a good enough transition in the minds of people, but considering the increased emphasis on global warming and pollution due to greenhouse gases, this percentage can only be seen going up.

The Use of Alternative Energy to Help Keep a Green Earth

La gran pregunta hoy es si va a reemplazar y reducir nuestros combustibles de hidrocarburos de dependencia como los combustibles del carbón y del petróleo. Energía alternativa es quizás uno de los más comentados y hablaba de recursos en la sociedad actual como un posible reemplazo de hidrocarburos. Es ha estimado que todos nuestros recursos naturales se habrán agotados completamente dentro de 150 años, y como tal tenemos que estar en continua búsqueda de las fuentes de energía alternativa viables.


Los tipos más comunes de energía alternativa actualmente en uso son la energía eólica, energía de hidromasaje y energía solar. Las fuentes de energía alternativas vayan de fenómenos naturales abundantes en el planeta, y como tales son en esencia libres. Es estas fuentes de energía alternativa que con frecuencia son perseguidas para proporcionar una fuente energética económicamente viable que puede ser utilizada por todo el planeta.


Echar un vistazo a estos tipos de recursos energéticos alternativos, somos capaces de ver las diferencias de cada uno y las ventajas que podrían tener sobre unos a otros como sustitutos de los combustibles de hidrocarburos.


Energía eólica


El uso de la energía eólica, mientras que una fuente de energía alternativa libre, sería en el escenario actual, la fuente de energía renovable más costosa. Los costos son elevados en gran medida en parte al hecho de que se genera viento turbinas deben ponerse en marcha a lo largo de los países con un número suficiente para garantizar la suficiente electricidad para satisfacer las necesidades de la población, esto incluye zonas donde la velocidad del viento no son muy fuertes. El evidente coste de construcción suficiente turbinas capaces de aprovechar la energía alternativa del viento es sorprendente.


Hoy es el uso actual en los países con la fuerza financiera para invertir en energía eólica y donde el clima permite suficiente viento alimentar las turbinas. Sin embargo, muchas granjas y comunidades rurales utilizan turbinas eólicas para proporcionar energía por sí mismos. En números bajos los costos inherentes de construir turbinas eólicas permite esa inversión a pagar por sí mismos muy rápidamente, sin embargo en grandes cantidades los costos aumentando gradualmente y como tal no han sido utilizados por muchos.


Energía solar


Como fuente de energía alternativa [http://www.globalearth.info], la energía solar se deriva el poder natural del sol. Aparte de la instalación del equipo necesario para convertir los rayos del sol en electricidad utilizable es generalmente libre. El costo del equipo necesario para aprovechar el poder del sol en los últimos días ha vuelto menos caro, principalmente debido a los avances en la tecnología. El costo de inversión para pequeñas instalaciones generalmente pagan por sí mismos con unos años más o menos.


Muchos de los viven en zonas tratando de ahorrar energía por tener rodando apagones a diario. Esto ya no es una preocupación para aquellos que utilizan la energía solar! Cuando se utiliza energía solar para alimentar su casa, mientras el generador está activado, tienes poder. La forma de que trabajan de estos generadores, es que durante el día la energía del sol se dibuja en el generador en celdas de almacenamiento. El generador convierte la energía solar almacenada en energía utilizable para su hogar. Esto significa que, incluso cuando el resto de la ciudad está bajo un apagón, tu casa puede seguir ejecutándose suavemente sobre energía solar.


Para los muchos que viven en zonas que están tratando de ahorrar energía por día y utilizando rodando día de apagones, el uso de la energía solar permite flexibilidad y pérdida de poder regular ya no sería un motivo de preocupación. Utilizando la energía solar en casa sólo requiere su generador esté activada para tener la potencia necesaria cuando se producen los apagones. Estos generadores funcionan de manera que durante el día la energía del sol se dibuja en los generadores a las celdas de almacenamiento y luego generador convierte la energía solar que se ha almacenado en las células en energía eléctrica utilizable para que una se utiliza en los hogares. En pocas palabras, apagones intermitentes o programadas permite todavía la casa todavía tener electricidad con esta fuente de energía alternativa.


Material necesario para construir sistemas para hacer uso de la energía solar como una fuente de energía alternativa para los hogares puede adquirirse fácilmente en la mayoría de las tiendas mejoramiento del hogar en las Naciones desarrolladas y ser instalada fácilmente en unas pocas horas. Paneles solares son fáciles de instalar en su cuenta, sin embargo hacerlo usted mismo a veces puede ser difícil, pero normalmente son contratistas que pueden hacer el trabajo de instalación de los paneles solares y generadores a un costo razonable.


Hydro Power


El uso del agua ha sido durante mucho tiempo en existencia particular su uso como un reemplazo de mano de obra, y también hay evidencia de algunos del primer uso comercial de hidromasaje poder como una energía alternativa están todavía en existencia hoy en el tan evidentes de fresado viejo y las instalaciones industriales. Hidromasaje poder hoy en día es poder productos utilizados en las escalas más grandes y las construcciones de represas y instalaciones de hidromasaje está aumentando debido a las preocupaciones sobre los recursos de hidrocarburos naturales agotamiento rápido.


Sin embargo, el uso de la potencia de hidromasaje y fuente de energía alternativa es limitado a zonas donde el agua es abundante y permite que el terreno natural para que pueda ser aprovechada en orden a turbinas que generan la electricidad necesaria. Algunos propietarios han sin embargo en los últimos tiempos comenzaron a dispositivo y desarrollar dispositivos para producir pequeñas cantidades de electricidad suficiente las necesidades de su hogar o granja al aire libre.


Mantener la tierra verde!


Utilizando fuentes de energía alternativas como la energía solar para proporcionar energía a su hogar es una de las mejores maneras en que puede ayudar a mantener la tierra verde! Energía solar no necesita quemar combustibles fósiles y de hidrocarburos y como tal le proporciona la energía necesaria sin agotar los recursos de tierras, teniendo en cuenta que en nuestras vidas no hay posibilidad de agotamiento de la energía del sol. El uso de esa energía alternativa asegura también que hacer su parte en mantener el medio ambiente más sano y limpio ya que no en todas formas contribuyen al agotamiento de los recursos naturales.


Independientemente de qué tipo o fuente de energía alternativa que decide utilizar para sus hogares, el hecho es que seguimos necesitando una fuente viable de energía renovable que puede ser utilizado por todo el mundo pronto, como el más largo que se tarda en encontrar esto, los recursos naturales más empobrecidos y agotados.

Lithium air batteries


As an alternative to conventional vehicles, electric vehicles are one of the promises of the future. Because they cause less pollution and not dependent on fossil fuels, electric vehicles are a viable option for transport over the coming years. However, not everything is as simple as it seems.


In recent years, a number of studies have been conducted to be able to judge the popularity of the vehicles electrical. And while there are many people who would love to buy these Green cars also there are a lot of people who prefers the traditional gasoline vehicles.

Why? Well, the answer is quite simple: EVs have no conventional speed of vehicles , have less autonomy and there is also a lack of facilities for cargo. But perhaps the most important factor is the cost, even with the tax facilities in many countries is the purchase of an EV, many people cannot afford them.

To partly offset these problems, scientists have developed litio-aire batteries for electric vehicles. Thanks to the implementation of this technology be could, for example, provide a better range of autonomy for so electric vehicles can travel longer distances.

The litio-aire batteries used two electrolytes: a metal (lithium) and the other is oxygen. Now, generally each battery has an anode and a cathode. When chemical reactions take place, the electric current flows through the battery. In the litio-aire batteries, there is a cathode, oxygen. The batteries are operated to come into contact with the oxygen present in the atmosphere. That allows to be light in weight.

When they are commercially available and if all goes as planned, the batteries of litio-aire bring us closer to a future better and greener. Lithium air batteries have the ability to store a huge amount of energy: up to 5,000 watt-hours per kilogram.

This is even more than the hydrogen fuel cells. The batteries of litio-aire is estimated to have capacity of up to five to ten times more energy storage than a lithium-ion battery. Thus, with these batteries in the car, there will be need to recharge the vehicle each one few hours in case that you want to travel great distances.

The main difficulties of the lithium air batteries

The batteries of litio-aire have their share of disadvantages. Although some assume that once it succeeds in passing, they probably revolucionarán have an EV.

Firstly, the remains of the reactions accumulate in the cathode in the batteries of litio-aire. This makes the passage of air difficult.

Secondly, the automotive industry itself is so great, that a large amount of lithium would have to be used to provide a massive production EVs with battery litio-aire. This is a gigantic task. Thirdly, the manufacture of the litio-aire batteries cost a fortune, and it is still difficult to such spending and investment is seen as profitable commercial eyes business's most important automobiles of the world.

How electricity: which is an electric field



In the 18th century, thanks to research of Coulomb, could be established that electric charges interact at distance, as well as the mass against gravitational forces. I.e., that a mass or load might inexplicably, without any mediator to notice another in their environments.


This idea was uncomfortable with physicists, even to the own Newton. Faraday proposed an alternative interpretation of very useful, based on the idea of field: space surrounding an electric charge is affected by its presence, since it modifies its characteristics.

In his attempt to represent him, Faraday described as invisible tentacles that are moving from the load. In this way, from the moment in which a body takes charge, this information or novelty is stretching in your environment quickly, indeed to the speed of light, and can eventually reach another load.

As it is true to speak of the interaction between a load and another, it is possible to also describe the same incident from the interaction of a cargo area that is.


To electric field can represent it with lines, by Convention, out of the positive charges and entering the negative charges. They indicate the direction of the field at every location, i.e. the direction of the electric force which would experience a timely and positive, load called burden of proof, if it is placed at each position in the field.

The number of lines is proportional to the intensity of the field, IE where the lines are very close, the field is large and where they are separated, the field is small.

Despite the many similarities between the actions electric and gravitational, should be clarified a difference: the gravitational field is always inlet to its source (a mass) while the electric field can be incoming or outgoing on the load that is generated, there are two different kinds of load.

View electric field requires some care, although it is possible to do it with some simple experiences. The simplest is to observe the direction of the hair covering the forearm when, for example,
We are approaching a bowed plastic rule.

Is also possible to obtain a representation at the level of the electric field linesor in the following manner: put a mixture of oil for the body and very small pieces of human hair, no more than 2 mm of
long, on a flat glass, such as a microscope slide. If we bring a charged object, observe that the orientation of the pieces of hair will follow the electric fieldlines.
