energy, you know, is a major concern of the human race. To produce energy alter the courses of rivers, forests cut down, you extract fuel from the heart of the earth.
demand for energy is growing steadily and without appropriate technology, our planet and its ecosystems are likely due to the huge energy thirst of man.

But if there were a way to get electricity without damaging the landscape? Again, if there was an energy source whose only waste is water salty? And if this water waste would be salty, but destined to become so and still come the beach cleaner than before?
Well this seems really in the possibility of osmosis plants. Howl

Let me explain. First, what is osmosis?

Osmosis is the process that occurs between two solutions separated by a semipermeable membrane, for which the less concentrated solution seeks to reduce the concentration difference with the more concentrated solution.
Basically if you put in a tank the same amount of fresh water and salt water and is separated by a semipermeable membrane, osmosis will cause fresh water and go attrraversi the membrane to dilute the salt water. During
this shift, the flow of liquid creates a certain pressure, which in the case of fresh water and salt water may vary between 12 and 30 bars of pressure, that is 11/28 times the atmospheric pressure at sea level! Not bad!

It 'just that the operation of a power plant osmosis: it "sucks" fresh water from the mouth of a river, is filtered and put it in contact through the usual semi-permeable membrane, with water sea. The osmotic flow created by the contact of the two types of liquid, will be transferred to the turbines which generate electricity.
The result will be electricity and salt water.
E 'should be noted that the placement plants at the mouths of rivers means that fresh water is not wasted because it was still intended to reach the sea and become salty.


You, O wise readers will say, "Yes! E 'science fiction! We will see this wonder in 30 years !"... And this is where you are wrong. In this wonderful country called Norway, has already been built the first prototype of a central osmosis.
the current state of technology, the plant produces only 4 kilowatts (enough to power two average homes) and it is estimated that the membranes are available today can produce about 3 kilowatts per square meter. Pochini when you consider that a typical power plant produces about 1 gigawatt of electricity.
But scientists (and investors) are very confident that the raw material is abundant, maintenance costs are low and the environmental impact is not only low, but actually could help clean up the water of many rivers / sewer leading to at sea.
It is estimated that about 50% of Europe's energy needs could be covered by these new, exciting technologies.

Howl, a dreamer by nature, already seen in this type of power one of those famous big cocks to integrate with the thousands of jets, which should draw energy to quench the thirst of our civilization.
