The graphene has properties that make it a unique material on our planet. It developed the first material that has two dimensions, is the finest and the toughest at the same time. The best conductor of heat, conduct electricity more efficiently than copper, is virtually transparent and is so dense that no gas can pass. And, more importantly, is a potential replacement for silicon chips in computer science.
Theoretically, graphene was at the head of scientists for decades, and it was not until 2004 when researchers at the University of Manchester achieved two-dimensional crystals of the material. Since then, several research teams have published advances that come to its practical application. For example, in April, scientists at the University of Texas managed to create a graphene sample of an inch in length. (Until then, there had been micro-sized).
Besides size, another challenge is to create sufficient quantities for industrial use. Several teams around the world work with various methods to achieve it. And they are getting interesting achievements. For example, in December 2008 IBM announced graphene transistors 26 GHz.
But where else will the field to highlight, in my opinion, will be on notebooks. The most tangible and immediately you will notice is that it will solve the problems to achieve total connectivity call: you can not load the whole day with the PC, your phone has a screen too small and the processor speed does not always have the joy wanted.
solution: a portable graphene a material capable of becoming a monitor (because it is transparent) and processor (ten times faster than silicon) at the same time, it is rolled and folded, which is as unbreakable as the diamond and having a single atom thick! Curiously
is that this new material is almost everywhere, but "packaged" in a way that does not perform so spectacularly: we had coal (carbon with amorphous structure), diamonds (crystal structure) and graphite (a form which includes sheets atoms). But we had graphene. Until, in 2004, Andre Geim and Kostya Novoselov, University of Manchester (UK), broke one of these sheets in the least scientific ever. So, not surprisingly, have received the 2010 Nobel Physics.
In his laboratory to study the graphite heat stuck on the sample and tore to remove the surface layers full of impurities. But Geim came up one day looking debris, and discovered that sometimes I could start a separate layers one atom thick that form graphite. So, I got graphene. So Novoselov and he founded Graphene Industries and no longer engage in conduct electrons at the university, but expensive cars on the street, it's more fun.
But I hope they go ahead with this material if it is all true (but rarely has not hit ... it is even cheaper)
The solar thermal is a branch of the solar energy is the use of heat energy from the sun in the lives of human beings.
can be used domestically, such as for cooking (stoves, solar) to generate hot water ( solar water heaters) or for heating. It is also used at industrial level, where water is heated to evaporate the water vapor moves turbines to generate electricity (power plants, solar thermal ).
's use but is now known thermal solar energy is solar water heaters for domestic use. These consist of two main parts, the solar collector and storage tank. The solar collector is a box approximately 2 m2 in which there is a series of tubes through which water, which when in contact with the sun is heated, a hot time is stored in the storage tank (an insulated tank, like a thermos) where it remains hot for when needed. These heaters can produce up to 91% of hot water consumed by a family, depending on usage and the amount of sun that is in the location of the heater.
Another use of solar thermal energy is taking a lot of momentum inside the houses are solar cookers, as they are very cheap (you can build one in your house) and easy to use. A stove solar can cook rice in about an hour and a whole chicken in 3 or 4 hours, so that the use of gas is reduced significantly and immediately in households that use them.
Within the fields of solar energy, solar power is cheaper than PV, so the energy is more support and growth has in recent years.
As I said, solar thermal also be used to generate electricity. This is done by building a tower on top of which there is a giant tank of water around the tower are placed thousands of mirrors that face the tank so the water is heated and evaporates, the vapor is forced to pass through turbines to generate electricity. At night the water condenses and fills the tank so the next day re-generate clean electric power.
Here's a way to optimize a bath ... Bathing is not if but can bathe gatherings while making it beautiful needs.
These stairs if they are best! I would like to see someone drunk trying to climb ...
who has stolen the stairs in my house?! as caught ...
That if it's art ... or the tower of Pisa and hosts! Now, I wonder if when the wolf blows this house will stand. I guess they do not the end of the story told and of course if the house is going to fall like the others to do it well ...
Here is the bath more comfortable the world. Who does not like piss sprawled. Either that or you Gasol and then you have no problems = D
This is a clear example of how to solve a problem in the most professional way possible. But when I close the door be careful that there is no voyeur by the grid xD
No Comments xD.
pegaaaaados is piss ...
Ea! home sauna. What you should be fine pores after a chimeneazo ...
buah! And they say that up and down stairs is a good sport. They have no idea. Down and picking up this a few times ...
Finally, shown here human intelligence. Thankfully, we are the smartest on the planet but ... That if me see your face like that was when they tried go home xD .
This afternoon I have learned that we are world champions. If yes, who I was going to say. I am not referring to World Cup and you're all thinking (always thinking the same thing!). But world champions in solar producer in the world. According Spain has managed to jump through connection, this weekend, the 50 MW thermal plant in Florida, located in the town of Alvarado (Badajoz) and owned by Renewable SAMCA.
The center has developed new technology for parabolic trough and has a thermal storage system by molten salts.
also marks a milestone in the industry for field size, solar that, with 550,000 square feet of catchment area, has become the largest in the world among the plants in operation.
Protermosolar said that, next to the plants already in operation in Spain, there are others already under construction and in less than a year could be connected to the network with an additional power of about 600 MW.
All the plants listed in the register of pre-allocation of pay in 2013 will achieve a power close to 2,500 MW distributed on 60 facilities.
The investment made by companies for the operation of thermal power plants now amounts to about 2,500 million euros and around 15,000 million accumulated in 2013.
