Role Plasma Plays in Nuclear Fusion

Google+ Pinterest LinkedIn Tumblr +

Nuclear fusion occurs when two atomic nuclei come close enough together to form a single, heavier one. This phenomenon powers the sun, the planets, and all the other stars and objects in the universal space around us. If we could only harness this energy source, then we would have an inexhaustible source of fuel. Moreover, this would be without the environmental concerns attached to carbon. The role plasma plays is critical to this achievement.

Concerning the Nature of the Phenomenon Plasma

There are four states of matter in physics, namely solids, liquids, gases, and plasma. Plasma is an ionized gas in which the positive ions and free electrons exist in equal proportions resulting in no overall electric charge.

Cold plasma is common in our upper atmosphere at low pressures. It also exists at extremely high temperatures in stars, fusion reactors we shall write about, and perhaps earth’s core. Scientists believe over 99% of matter in the universe we can see is plasma. Hence, this excludes the dark matter that we can only assume exists through celestial observations.

Plasma is usually super-heated because of the energy required to separate the electrons and the nuclei of atoms. Scientists are experimenting with plasma to create a new form of nuclear power they call fusion.

The Role Plasma Plays in Our ‘Normal World’

On earth, lightening creates plasma so we have it in relative abundance. We encounter cold plasma in plasma globes and lamps in children’s rooms, neon signs, fluorescent lamps, and television and computer screens.

We are seldom aware of the role that plasma plays this way. And so we accept it as a form of energy and move on.

The role plasma plays will expand exponentially, if scientists find a way to harness the immense energy of fusion for human good. Sometimes they believe they are tantalizingly close. At other times, the future seems a long way away. We are excited there is a future like this beyond carbon. This could turn out the salvation of our planet.

I tripped over a shrinking bank balance and fell into the writing gig unintentionally. This was after I escaped the corporate world and searched in vain for ways to become rich on the internet by doing nothing. Despite the fact that writing is no recipe for wealth, I rather enjoy it. I will not deny I am obsessed with it when I have the time. I live in Margate on the Kwazulu-Natal south coast of South Africa. I work from home where I ponder on the future of the planet, and what lies beyond in the great hereafter. Sometimes I step out of my computer into the silent riverine forests, and empty golden beaches for which the area is renowned. Richard
