Coal, a drug for mankind very difficult to leave

Published in Linkedin: Coal, a drug for mankind very difficult to leave (28/11/2014) If someone asks for jobs with less future, probably in all lists would write the coal mining . Coal has historically generated many jobs, however mechanization has been declining number of employers; but in many parts of the developing world is still mining, sometimes in border on slavery, which is feeding (bad eating to be exact) many people from earliest childhood. Now a danger is hovering over this form of living. Although coal will remain nearly 300-year to explode with current consumption, but the need to reduce CO 2 emissions questions the continuity of this mining. Coal was the engine of the Industrial Revolution . The steam machines from the eighteenth and nineteenth centuries moved thanks to black stones that we could burn. But the twentieth century discovered a new fuel: the Oil , which was more manageable, easy to get and it has more potential uses. Later he appeared a third co...

Is fresh water ending in the World? No, but we've got problems

Published in Linkedit: Is fresh water ending in the World? No, but we've got problems Current humanity has got enough knowledge and technical to convert salt water into fresh water. Global water doesn’t change its amount, and sea water we can convert in continental water as we want. But there is a little problem: is expensive. Water is the most abundant mineral in the Earth's crust, as I said in “ Water ”, which is the why that life is based on it, summarize to have other physic-chemical properties that make it unique, which makes it invaluable; although its abundance relegates it to have a residual value. Brazil somewhat smaller than Europe, and it has a patchwork of climates, however its position in Ecuador it has got a rainforest in main part of its territory, yet there are also deserts. The Brazilian population lives mainly on the coast with high densities of population, but they haven't water problems because they live so close to a forest. Until today , the...

Oil falls below $ 90

Posted in Linkedin Oct 16 2014  https://www.linkedin.com/pulse/article/20141016104438-186157434-oil-falls-below-90?trk=prof-post It seems very good news. Historically low price of energy reduces production costs especially with an extremely tech world as the current. But now the paradigm is completely contrary , the financial economy governs the world relegating industry and agriculture to a second order. Today buy and sell moves the world not produce. Oil is one of the more products that financial markets buy and sell, and it mean that follows the marked rules in terms of price. But oil had an artificial price. When created OPEC, it was grouping major countries which had greater oil reserves by the standards of that time; it created a Mega Dumping that killed the oil market, because if the price down production stopped and this turned up. Since the 70s the world energy economy has been captive to the decisions of these countries. Although now it's different, most of...

The great flood

Sea level rises slowly as glaciers melt threatening the population Do not be deceived . A bad summer does not mean that global warming has stopped. In fact experienced bad weather, especially in winter, is largely the result of increased atmospheric activity caused by a higher amount of energy. In the same way that a hot summer does not mean Global Warming, it is very cold in winter nor does it mean it will start an ice age: Climate Change is a long process, but not necessarily slows . NY under sea This winter there was a Polar Vortex that struck northern America, and Antarctic takes an extent never seen; but the average global temperature has continued to grow , which refutes those who spoke about the stop of Global Warming. This warming is melting, not only Arctic Icecap, but is melding also all the continental glaciers. Photographic evidence more observation from satellites leave no doubt. And the continental water just melts inexorably into the sea. The ocean level r...

Windmills or helical turbines

The Windmill has become part of the passage, but it can also become a memory Don Quixote fought to the windmills in the sixteenth century. The wind has been joining to the wood burning one of main human sources of energy. Not long ago, and even today in a sportsmanlike manner, our ships crossing the seas by the wind; and in everywhere we can find mills which are grinding grain or pumping water. So history offers us a way to replacement the fossil power station in front of the disaster of global warming; but has several drawbacks as usual with all renewable energies, hence the difficulty imposed on fossil fuels. When I wrote “ We must change the way we see energy ” I had exposed the difficulty of supply our demand, not only amount of energy and power but punctual peak of them. Another problem is an eco-landscape. The mills are huge blades that rotate at speed relatively slow but relentless with birds that cross the large area covered by them; may appear to be somewhat ane...

Are we alone in universe?

Every people in every time made this question when they see the majesty of night sky. The answer is No . Our Galaxy ( Milky Way ) has 200.000.000.000 stars and is sure that exist more planets as our where there are life. Other thing is if these planets have intelligent life, if these intelligent lives have a technological civilization, and technological civilizations have technologies compatible with ours.  We aren’t alone that is sure, but has our neighbors anytime visited us? More people believe that is true and this is happening now. They think to have conclusive proves of this fact, but science community say these aren’t valid and today officially there aren’t evidence of extraterrestrial are coming now or they were coming before. We would like that a more intelligent people than us, come to earth to solve our problems. ET is the new god who is different than traditional in it lives in the same dimension to us. Today society is finding new referents and new trans...

Is there room for hope?

Imatge
People talk a lot, but they made less. Time is passing and world is turning without stopping and waiting what we decides to do. Weather is every day more extremely, nature is deteriorating faster and number of persons in the world is growing rapidly. But nobody do something to arrange the trouble (read  Trying to understand Warsaw ) . But could we do something really? This is a very difficult question to answer. First we have facts in front us but what is happening really isn’t so clear; because in one way there are a lot of analyses which are showing many kinds of scenarios and in other way facts are seeing as own prejudices says they would be. Second there are more interest playing in climate fight: we have whole industry of fossil which doesn’t want to lose this lucrative business , but other industries which have invested millions in facilities that needs oil or coal (power companies i.e.), and we must not forget the main industry of this world: financial economy whic...
