FLU GAME RANKING N1H1 DO YOU KNOW THE SYMPTOMS?


The Grade 6 students conducted a morning shift box to differentiate flu from the flu N1H1. Was carried out in Excel and find pictures to identify the symptoms. Learn to prevent. Excellent job!

NUMBERS AND THE SOLAR SYSTEM


During this year we worked with students in Computer grade 3 morning shift, the Solar System. Was carried out in Word and taking into account developed in class. Congratulations! for boys for the precision and dedication.

simple scheme in Chile

non-conventional renewable energy: Solar Chimney in Chile. all know how important it is to diversify the energy matrix of our country, yet all is said but nothing is done, not enough to pass in the Senate a bill that forces in Chile generate 10% of energy by renewable means by 2024, apparently lived rationing in the 90's was not enough to take measures to resolve the underlying problem. The National Institute of Statistics (INE), in your newsletter on June 16, 2006, announced the distribution of electricity consumption in Chile. This study yielded the following results:

The generation of these 51,575 GWh, Chile's generated as follows:

is, the solar energy in Chile is not being considered, it is wasting energy potential in the north of our country. It is good that wind power is the open road but is it enough?, do not know, will be the subject of study for later.

A great alternative power generation is solar energy, due to low investment costs of both generation and maintenance.
my point is that we must seize the north of our country by industry high solar radiation as shown below.

This energy can be harnessed in many ways, small-scale or large-scale household level industrial and mining. My point is made elsewhere in the world, and of course Chile can not be left behind.
last year submitted the draft Development Fund for Scientific and Technological Advice (Fondef) called "Building a scale from Solar, clean and renewable resources, which is based on the construction of a great fire of about 1000 meters high and at its base, covering a large area, is a kind of greenhouse air temperature rising making it up through the chimney, and turn this air can spin turbines to transform that energy into energy supply.

and maintenance costs are obviously muchomenores generation compared to conventional power generation, from $ US_ from 0.4 to 0.7 cents / kWh.
What today is being expressed is to build this fireplace supported on a hillside in the sixth region, however, I think the best option is to build it between the first and third region so as to take on a higher radiation solar and this also make a contribution to SING.
Now the main reason to do in the north of our country, it is because mining is the sector that consumes more electricity with an Approximately 32.3% of total consumption in Chile.
I think this alternative is that Chile must continue to avoid energy crisis like we are living now, innovative power generation alternatives and we do not have to rely on neighboring countries to illuminate our homes, therefore, to consider construction of a nuclear plant would be as prepared to face a similar case as we are living now with Argentina.

A solar chimney - often referred to as a thermal chimney - is a way to improve natural ventilation of buildings using convection of air heated by solar energy passive.

A simple description of a solar chimney is that of a vertical shaft utilizing solar energy to enhance natural ventilation stack of flats in a building .

In its simplest form, a solar chimney is a chimney painted black. During the day solar energy heats the chimney and the air inside it, creating an updraft in the chimney.

The suction created at the base of the chimney can be used to ventilate and cool the building.

In much of the world is simpler to take advantage of prevailing winds from the site, but on calm days and warm this type of fireplace can provide ventilation where otherwise there would be no.

There are however a number of variations in solar chimney. The basic design elements of a solar chimney are:

• The solar collector area: This area can be located at the top the chimney or can include the whole shooting axis.
• orientation, type of paint, insulation and thermal characteristics of this element are crucial to attract, retain and use solar energy.
• The main ventilation shaft: The location, height, cross section and the thermal characteristics of this structure are also very important.
• The inlet and outlet: The size, location and aerodynamic aspects of these elements are also significant in performance.

Building on the same principle of operation have been proposed solar power generation systems with a large greenhouse at the base to heat the air which then rises to a high speed from a high chimney where wind turbines are located . Also called hurricane plant.
