Some articles to read about these two issues:Solar-powered plane lands in New York to complete cross-country trip
Swiss pilots attempt first around-the-world solar flight
Apple U-turns after Taylor Swift slams music policy (What does a 'U-turn' mean?)
I am going to talk about solar-powered planes and about what consequences will have in the future. This types of planes has been recently discover. This ecologic planes use solar energy to move throw the air and in their wings there are solar panels which obtains the energy from the sun.
ResponderEliminarThe advanteges of solar-powered planes are: The air it isn't polluted because they use green enery, the solar energy doesn't disapear as the kerosene. The disadvanteges are: that this type of tecnology isn't developed enough, because this planes can't be flying for more than half an hour and they can't either transport a lot of weight.
All in all, I think that this planes in the future will be very useful, because one day the fosil fuels will disapeared. I hope that goverments investigate more in this type of tecnology, because it will be our future.

I have read this article and I think that this aircraft is fantastic because it was be able to complete flying a section of New York city during the day and then it landed at New York's John F Kennedy International Airport the Saturday night. It is very important because this aircraft hasn't got engine, therefore, it doesn't use fuel and it is only propelled with solar energy. The pilot was very happy because he said that the plane was able to fly day and night without fuel.
ResponderEliminarI think that renewable energy is a great idea for the future and I think the government should do more to help people who are investigating these advancements. Nowadays, people use transport powered with diesel, gasoline, ethanol, bio-ethanol, lead, ....... these fuels are highly polluting for the atmosphere, the environment and for ourselves. Renewable energy has many advantages, but it also have some disadvantages, for example, renewable energy don't give so much power as non-renewable energy.

ResponderEliminarI am going to talk about the music war between the singer Taylor Swift and the company Apple. It is true that all of us enjoy listening to music and that we don’t like paying for it and the solution it is to download it through illegal pages or to listen to it in musical platforms without paying. The problem is that if we don't buy the music, or any CDs and we don't even pay for any music service, the singers and musicians don’t earn money. They live off the music and they hope to get some profits, thing that doesn't always happen. I agree with her, because I reckon that she is doing her work and she must make profits from it.
ResponderEliminarIn contrast, it is true that Apple wants the best for their customers to keep them happy. Although the solution isn't this one.
The girl is very brave fighting for what it is from her.
I think that U-turn' means in Spanish, cambio de sentido.

Since appearing internet is very easy access to all kinds of music, so we can listen to music at all times without having to buy it. It is true that we all young music downloaded by mobile applications and have all the songs you want without having to pay anything.
ResponderEliminarOn the one hand I agree that singers live music and many others working in the world of music. It is not fair for them to do a job for months to earn nothing.
On the other hand the internet has become a very easy tool to use and that we all have in our homes and in our phones, so it is very difficult to control any information is there, even the music.

ResponderEliminarI think that Apple is one of the best brands in the world because it has a lot of electronic devices. The Battery of its electronic devices is very good and it lasts much more that other batteries. Its image is also extremely good and also its physical appearance. His security is one of the best thingS that iOS has. It has much more than other mobile phones.
ResponderEliminarApple is also one of the most modern deviceS and one of the most known in the world. Apple is a very modern and active company and it brings to market a new mobile or a new device very quickly.
Apple also has some problems like its price. Every time that Apple releases a new mobile or device you have to pay a lot for them. You also have to pay to use some applications like music or games. IF one of your apple devices breaks down, you will have to pay a lot for it repair.
As you can see Apple is a very good brand, but is very expensive. I wish that one day their prices will decrease.

ResponderEliminarTechnology is always surprising us. More and more amazing inventions are appearing everyday. The airplane was made a long time ago, but have you ever seen an airplane that only uses solar energy? Well, yes, this has been made. A solar-powered aircraft flew over New York a few years ago. Unfortunately, the revolutionary plane, powered by some 11,000 solar cells on its oversized wings, had to land earlier than expected because of a problem on his left wing. However, that doesn't mean it's not a great invention.
ResponderEliminarOn the one hand, solar planes are a great idea because today there is a lot of pollution and we have to do everything possible to reduce it. The fuel that planes carry, and that is spread all over the sky when they fly, is very polluting. Moreover, sunlight is a clean energy that never runs out. "It was a great success for renewable energy" Borschberg said.
On the other hand, as I said before, the plane had to land earlier because there was a problem in one of the wings; what would happen if it happened in a normal flight with a lot of passengers? Besides, solar panels are very sensitive and planes fly very fast so it is very likely that an accident can happen during a flight. Moreover, at night planes couldn’t take solar energy from the sun and they may have run out of power.
All in all, solar-powered planes can be very good for us but we have to be careful because sometimes they can be dangerous. In my opinion, they should invent an airplane that has both solar panels and fuel.
Today for my taste and for that of many people apple is the best brand of mobile and computer.
ResponderEliminarAll this is due to the fact that it has a great mechanism inside and that its battery is quite good, it has good graphics and a good screen vision and it also works at a fairly fast speed.
Another good thing about this brand is that it makes new products in a short time, so every x months we have a new mobile or computer.
But everything that this brand has is not good since anything from this brand costs a lot of money, and some cannot afford it.
In my opinion, I think that if it were a little cheaper, more people would buy it and earn much more money.
Salvador Pretel
For me Apple is the best brand of electronic devices.
ResponderEliminarI have different devices from this brand and its battery lasts longer than other brands. Another factor that also seems to me to be of higher quality is the camera. It is characterized by everything because its operating system is not Android, it is IOS and for me it is more complete than Android.
I think that although they are more expensive, I think they are worth buying.

ResponderEliminarApple is one of the best brands of both phones, computers, and now smart watches, although it is highly over-rated because if it is true that computers and smart watches are coming out very well and having something that makes them better than other brands, but with regard to mobile phones, if it is true that before if they offered you something that had no mobile of any brand, but that has now changed they are far behind other brands that have stuck a great evolutionary change for the better, whether new brands like those of a lifetime, and it’s no longer worth buying an apple mobile because the first thing you’ve left behind regarding mobile quality for many apps you have to pay or directly are not available and of course the exorbitant price they are worth when, there are mobile phones from other cheaper brands and much better.
ResponderEliminarI think that It possible that I buy one computer of apple, but that I don't buy is one phone, because the cost a lot of, and there are phones of others brands that are more good the one apple.
It´s certain that the pollution in the world is changing our lifestyle, and some organisations and scientist are studying how we can stop this problem.
ResponderEliminarSolar energy can be the answer to this problem, an infinite energy that doesn´t pollute and that can be used to mostly everything. It can sound like a mere dream, but nowadays, solar power is used to many things, for example, some houses warm water with this, some places uses it to produce electricity, and even, there are some cars that use solar power instead of common fuel.
Talking about Apple, I think that years ago, it was the best brand related with technologies, it offered new devices with new features that no one has ever seen before. Nowadays, it is a common brand that only wants money and that it offers mediocre products at high prices. Some brands are gaining more popularity than Apple these years , and this can affect their sales in a future.
I hope this company notices this soon, so it could be the one that it was in a past.

Technology always surprises us. More amazing inventions appear every day. The plane was made a long time ago, but have you ever seen a plane that only uses solar energy?
ResponderEliminarOn the one hand, it is not very common to see airplanes that work with solar panels, since thanks to technology, means and people are able to manufacture safer and more modern airplanes than those that we did not find before, since at that time it had not been developed still current technology.
On the other hand, the planes that were manufactured before, which worked with solar energy, were less expensive than those of today, since the labor was cheaper and also did not use fuel. The problem with these is that you depended on having the sun, since if there was no sun they could have a problem during the flight.
In my opinion they should make airplanes that have both options, both that the tanks are filled with fuel, and that they go with solar energy, this being the most used and in case of emergency use the fuel.
World nowadays has changed along the years. It was difficult to imagine decades ago a car which works with electricity or even electricity obtained from the sun. This new invention has changed the world’s economy and especially its environment for good and is making that more and more things like cars or even your house lighting uses this clean and renewable energy.
ResponderEliminarFor example, there are lots of new businesses that are working on renewable energy such as solar and wind energy which don’t pollute the environment and it’s much cheaper to obtain than other non-renewable energies such as petrol or gas, which are more expensive to obtain and they’re very harmful substances for the environment. Actually, nearly everything is working out with electricity, which is a clean type of energy and easy to obtain. I thing that in a future everything will be working out of electricity; from household items to airplanes.
Mobile phones are also changing. They’re getting more and more expensive with the pass of the time. Obviously, this depends on the mobile brand and the model. Sometimes it's worth it to buy a very expensive mobile if you know how to use it in the correct way and if you know what each of its applications is for. I think that people, especially teens are making a serious mistake when they buy the last model of an expensive brand because they only want the mobile phone to take some photos and use it for chatting or calling some friends and they’re not going to use it in the correct way.
To sum up, I think that renewable energy is one of the best inventions made by the human and I hope that in a future everything will work out of this clean energy to help the environment and to look after the earth.

ResponderEliminarThe technology is changing and improve quickly. I had never thought that some day I would see electric cars or robot which we could use to help medicine and industry.
One of the bigger brand of mobiles phone in the world is Apple who sell many mobiles phone around the world, from my point of view his qualities are the best of all, for example the camera are incredible it takes amazing photos, the battery you can spend more time without charging it because the battery lasts longer than other brands of mobile phone.If you can buy an apple, you buy them although they are so expensive, they are the best qualities in the market.
I believe they are incredible because they can try the first times around the world with solar flight which only can works with solar energy.It is a difficult plan because there is risks because they spend much time flying, they couldn’t sleep and they need do yoga.
Bill Read said that solar flights was not yet even remotely ready for any applications in commercial flights because unless there is a quantum leap forward in solar cell technology, solar cells can’t yet be considered as a sole power source for aircraft.
