GLOBAL WARMING'S HAND ON GLACIAL ICE

We are aware that the global warming has adverse effects over this earth. Glacial ice has also been affected by the global warming. It the past, before global warming, there were huge regions of glacial ice. The global warming has increased the warmth of the globe. This warmth has caused for melting of glacial ice. This is the reason for declination of  glacial ice region. At present itself, the glacial ice region is present in very acute level. If such global warming continues, its sure that within few years there will be no glacial ice region. The graphical representation of the glacial regions in the past and present are show below. This would give you the clear picture of the present scenario.

The main reason is the emission of Carbon dioxide into the atmosphere. It was found that around 190 billion tons of carbon dioxide is emitted into the atmosphere every year. Out this, 7 billion tons emitted due to human activity, 91 billion tons due to biological activities taking part in the ocean and the rest due to volcanoes and decaying to terrestrial plants. 

You might think that human activity is contributing the least amount. But if seen properly, the other two have been increased due to indirect human activities. Our activities, like excess mining, excess deforestation, etc., all such activities in excess has disturbed the nature. 

Its very simple, we are disturbing the nature, so in turn its disturbing us by volcanoes, earthquakes, tsunami, etc. This way we are contributing to the emission of carbon dioxide into the atmosphere. We are polluting the water bodies by passing various industrial wastes into it. This affects the normal life cycle in the water bodies like oceans. This again will disturb the carbon dioxide balance between the atmosphere and ocean. So excess amount of carbon dioxide gets emitted from the oceans into the atmosphere. 

This way we are whole responsible for the excess emission of carbon dioxide into the atmosphere. So we have reduce the emissions of carbon dioxide by all means. We have to save our earth & natural resources.

Baby Polar Bears the next victim of Climate Change

Climate Change has become more dangerous that nuclear weapon. If its intensity is not controlled, it could be the most disastrous weapon. This is now mainly affecting the wild life, aquatic life to a greater extent. We too are being affected but to an acute level, but within no time it will affect us.

After affecting coral reefs, rare spices of aquatic life, the climate change is targeting the Polar bears cubs. We know that, due to the climatic change, the ice caps in the polar regions are melting down. This means that the Arctic region is declining. Arctic region is the habitat for the Polar bears. So as this Arctic region gets declined, so they are swimming mile together in search of their new habitat.

The elder Polar bears can swim such long long miles days together, but the small once, its highly impossible. Even the elder bears losses considerable amount of weight during such a tedious journey. They lose around 1/4th of their weight.

It was found that the polar bears were swimming approximately 426miles to reach a region which is similar to their habitat. Even that region is very small, also due to increasing climate change problem, even it is expected to be lost soon. The baby polar bears just swim small distance, and die. This way many babies of polar bear has lost their life.

We know that, these polar bears are the poster of climate change. If this climatic change goes to serious level, soon we have to search for some other animal, or even time will come for putting our image too for the poster, if not controlled.  

We have to take some initiative to solve this problem. If it is not solved, we might also be facing such problems sometime or the other. So lets put our hands together and save our earth & natural resources.

Effective Reuse of Old CARS

Technology is developing day by day. Everyday there is improvement in all fields. Everything is becoming absolute as day pass. In the automobile field its also the same. The people are going for latest models. They will discard the old cars. So it forms solid waste. So it gets dumped on the earth. With an hint of creative idea we can even utilize these discarded cars the best possible way.

These can be utilized for making some new creative form of parks, gardens. So along with entertainment, environment problem like solid waste disposal can be solved. These parks can be the initiative for creative work. 

They can also used in creating museum. This would show the future generation of the past cars. They can see to themselves how the automobiles have developed and much more. Its all how we represent them. If we dump them, it becomes waste and the same thing if we present it quite different way which all like to see. it would surely welcomed and encouraged.

By doing such creative things, we can make the best possible use of them.

If it cant be used for such purpose, we can go for the better way like using its various parts as scrap, recycling them instead of using the fresh raw materials again and again. So raw materials can be conserved at the same time, the energy required to process such scrap will be some what less as compared to the fresh feed. 

So don't waste the resources we have, utilize them to the best possible way. This can help to save our earth & natural resources.

Carbon dioxide a new boon-----used as fuel.

Carbon dioxide along with sunlight produces methanol and gasoline which can be used as fuel. A new innovative method that could reduce the amount of carbon dioxide in the atmosphere.

As everyone know that the excess amount of carbon dioxide in the atmosphere is the prime reason for causing global warming. The global warming has become a greatest problem for the past decade or so. Along with global warming we are facing problems regarding the energy availability. As our fossil fuels are on the verge of extinction, everyone has been alerted for an alternative source of fuels. Till now many alternative fuels have come, but this is going to be more interesting. As this will give solution for two problems at the same time.

Here carbon dioxide along with sunlight can be used as fuel. This will reduce the amount of carbon dioxide in the atmosphere. Along with this energy will also be produced that can be utilized.

In this, carbon dioxide is converted to petrol using sunlight.This is achieved by recovering the building blocks of hydrocarbons by reversing the combustion process. The product so obtained can be synthesized to produce fuels in the form of methanol or gasoline. Already this technology has been tested for small scale utilization. It might require decade or so to commercialize.

Extracting fuel from carbon dioxide is found to be some what expensive. But on fine research it could be optimized. Also the reason for encouraging it is the ever increasing price of crude.

This process uses solar reactors named Counter-Rotating Ring Receiver Reactor Recuperator  which is simply called CR5. This solar reactor uses sunlight and breaks carbon dioxide to carbon monoxide and oxygen. Its simply a heat engine, but it does chemical work instead of doing mechanical work which is done by the normal heat engine.

The prototype that is used has the size and shape of a beer keg. This contains 14 cobalt ferrite rings each having diameter of 1 foot and rotates at 1rpm(revolutions per minute). An 947.23 square foot solar reactor traps huge amount of sunlight into the reactor. This is used to heat the cobalt ferrite rings to about 1427 degree centigrade. At this temperature the carbon dioxide breaks up to carbon monoxide and oxygen. As breaking of carbon dioxide to carbon monoxide and oxygen is an endothermic reaction, it absorbs the heat from the rings. When the rings temperature goes down to 1093 degree centigrade, it is exposed to carbon dioxide.

As the cobalt ferrite rings now lack oxygen, it takes it from the carbon dioxide that it is in contact with. There by leaving carbon monoxide, which serves as building block. This building block is the source for the formation of  hydrocarbon. Further this can be converted to methanol or gasoline, which is a fuel. After the formation of fuel, the cobalt ferrite ring comes back to its original state and is ready for another cycle.

This way the carbon dioxide which is considered as a problem can be utilized properly to give energy.

This to has one drawback, heating of cobalt ferrite ring to such a large temperature at commercial level. Heating for small scale has been achieved. So we have to find how to commercialize it.

By doing this we can save our earth & natural resources.

If anyone has any idea regarding the heating of rings for commercial scale can give. Its our earth and we have to save it.
