ways to save earth

 Let us make our future now, and let us make our dreams tomorrow's reality.

Hi guys, this time I am come up with top 3 inventions going change the earth has a whole. Last week we saw what are the man-made disasters and some tips to overcome the obstacles. We alone can’t change the entire world so we need some help from our nature, technology and of course from our past. The invention and discovery you’re going to see are currently under process once theses process hits the floor, it’s going to be an enormous change in our lives. Here we go!! Remember, don’t forget to share your knowledge.

Graphene.

 Would you believe me, if I say the whole world is going to change by a simple writing instrument?  That is “PENCIL”. Most of you don’t believe I am sure pencils going to change the world, I will tell you how. We all used pencils right, but we never care about the graphite inside it. YES, the graphite in the pencil is made up of carbon atoms. Just imagine your drawing a straight line using a pencil in a plain paper if you see the line through a microscope we can notice graphite look like a multi-layer of thin papers. If we separate the graphite atom one by one we will get a single layer of carbon atoms “GRAPHENE”. In 2004 Andrew Geim and Constantine Novoselov got a noble prize for finding Graphene by using a scotch tape and graphite powder yes, they did it. Graphene is one of the strongest material found on earth, its 1000 times stronger than steel. It’s one of the thinnest materials on earth and it’s flexible too. Another fascinating thing about this material is it is 1000 times better conductor than copper. We can charge our mobile phones in 5 seconds and we charge our battery car in 30 seconds. Creating solar panels made up of graphite will much better than now. We don’t need any nuclear power stations if graphene comes into play. We know 70 per cent of the world is made up of water and only 3% will be suitable for drinking we can use graphene to make salt water into normal water. The only problem in graphene is its manufacturing is really tough. Hope now you realized the real value of our pencils.

Hydrocarbon.

One of the most hated names in India right now especially in Tamilnadu. Before opposing something we must know what exactly Hydrocarbon is. The name hydrocarbon seems to be so simple it means a combination of one hydrogen atom and one carbon atom, one carbon, and four hydrogens became methane, one carbon and 8 hydrogen atoms became ethane and the reactions go to a chain. We are getting 46% of electricity from oil and coal so one day there won’t be any coal to dig and no oil to mine. At that time we can’t say we don’t want a hydrocarbon project because it is a major source of energy. Let’s take an example if we heat the methane it will react with 2 oxygen molecules and give as water and carbon dioxide while doing this process will produce lots of heat energy that energy can be used to produce electricity.While government digging agricultural lands for this methane projects nearly  14 to 25 million tonnes of methane gas escapes to atmosphere from our earth. The main source of methane gas is “garbage”.  We can take 40 kg of methane from on garbage. Nearly 1 billion ton of methane can be taken from garbages alone for a year and it can be used as a fertiliser for more 90000 acres of land. By doing this we are not allowing methane to escape into the atmosphere because methane is denser than carbon dioxide so global warming can be reduced considerably.

Decoding the past.

In my point of view, the life of future lies in the hands of past.Literally, we forgot many inventions and banned them even we destroyed them. We must get back those inventions to prevent our future.Some of them are mentioned here. If tesla’s death ray rediscovered now it will an immense development top in defence. Death ray which can destroy missiles 200 miles before they reach.Starlite is an invention which can withstand nuclear acctack which is made up of 23 types polymers.Still many to go. Chronovisor is a supernatural invention that may use to view past.  World is hiding something from us.
