Graphene….. Answer for your energy starvation

We are in need of energy in stored state, for operating our systems, instruments etc. without interruption.  Lithium Ion batteries mainly handling these requirements.   But the cost and weight of the Lithium batteries and chance for explosion are the drawbacks lying with these.  The unending search of alternative energy lead to the invention of novel idea  of producing and storing energy thru graphene .

 Graphene is an excellent conductor electricity and energy and is an extremely light compound , where  as Lithium-ion batteries are bulky and heavier than graphene.  Graphene batteries almost eliminates the possibility of battery explosion.    Normal lithium-ion battery stores around 180Wh per kilo, while graphene stores 1000Wh which makes latter more efficient space wise.  The systems running of graphene can run longer uninterrupted without frequent recharging and they charge much faster.

 The countries currently on the forefront are China , Brazil,  Canada and India, in graphene production and China stands  at the top with a mammoth production of  630,000 MT

2886 KILOMETER's DEEP ; EARTH CORE SPINS, STOPS AND SPIN AGAIN TO OPPOSITE DIRECTION !!!!

The revelations about the universe day by day remind us about this proverb : -

Infinite…unknown…indescribable

The latest among this is the discovery about the earth core.

The melting earth core in the shape of a ball is rotating !!!! It will rotate in clock wise direction…then gradually slow down…

then again start to rotate…but in the opposite direction…anti-clock wise

 The news about the new discovery came in the Nature Geoscience Journal  says, study of the seismic waves from repeating earth quakes over the last six decades points to the fact that core’s rotation stopped around the year 2009 and slowly restarted in opposite direction .

 LAYERS OF EARTH CORE :-

The scientist concluded the  above  discovery is the outcome of the series of the previous findings about the composition of earth core. They also found that earth core is comprised of 7 layers and the inner core is spinning like a ball. 

Astonishingly while describing about the 7 layers of Sky, the Holy book of Quran said in Chapter Al Talaq, ver 12: Sky and earth have 7 layers.

ٱللَّهُ ٱلَّذِى خَلَقَ سَبْعَ سَمَـٰوَٰتٍۢ وَمِنَ ٱلْأَرْضِ مِثْلَهُنَّ يَتَنَزَّلُ ٱلْأَمْرُ بَيْنَهُنَّ لِتَعْلَمُوٓا۟ أَنَّ ٱللَّهَ عَلَىٰ كُلِّ شَىْءٍۢ قَدِيرٌۭ وَأَنَّ ٱللَّهَ قَدْ أَحَاطَ بِكُلِّ شَىْءٍ عِلْمًۢا

LITHIUM BATTERIES FOR SOLAR POWER STORAGE

As a source of environmental friendly , renewable and abundant energy ... Solar power by using various techniques rallies ahead. By enacting various laws and providing subsidies by various countries the future of solar power tapping seems bright.  

The scientists have assessed that the amount of sunlight that strikes the earth's surface in an hour and a half is enough to handle the entire world's energy consumption for a full year.

There are two main types of solar energy technologies—photovoltaics (PV) and concentrating solar-thermal power (CSP). While in PV the sunlight is absorbed by the PV cells .  The energy produces electrical charges by releasing electrons from atoms

In CSP systems mirrors will reflect and converge sunlight on to receivers 

and convert in to heat, which can be stored for future use or can produce electricity directly .  This method is mainly used in large power plants.
