I will start with some facts and small stories. So, read
completely then only you can got the solution.
Our earth was surrounded by 72% of water. In this 97% of
water is sea water and the remaining 3% only drinking water. Now a days many
people are died due to lack of drinking water. One day this 3% of drinking
water will run out. Similarly due to the
vehicles our earth is polluted more.
THEN HOW TO SURVIVE?
You may tell, using desalination process we can convert the
sea water into drinking water. But we have one problem if we want to start this
desalination plant we need more than $19 trillion dollars and also we need many
resources to run this plant. So, it is not economical.
Similarly if we use electric cars to control pollution but
also we have some problem it takes more than 20 hours to charge
completely. So, it is impractical to
use.
SOLUTION:
We can convert the
sea water into drinking water using simple filters. And also we can completely charge
our mobile phones in 5 seconds and charge our cars in 30 seconds.
LET'S SEE HOW IT IS POSSIBLE?
Pencil is the main reason for this. I think you do not
believe this. let’s see how it is
possible? If we see the pencil’s graphite in atomic microscope we see the many layers.
The single layer is called Graphene. It looks like honey comb structure.
In the year 2004 Prof Andre Geim and Prof Kostya Novoselov got noble prize for finding this graphene.
It is the strongest material on earth, 1 million times thinner than paper and
it is flexible and transparent.
The most important is graphene is 1000 times
better electrical conductivity when compare to copper. So, in future we have
only this type of graphene electronic products like thin flexible phones etc.
If we use graphene super capacitor as a battery we can
charge our mobile phones in 5 seconds and charge our car in 30 seconds. And
also we can easily convert the sea water into drinking water by using this
grapheme material.
Thank you we will meet with another one interesting topic.
