The nuclear fusion

Stars generate heavier elements by using a process called nuclear fusion, but how does it actually work? Is it industrially possible?

Nuclear fusion requires certain conditions to be achieved. First of all, the atoms put in doubt must achieve an unbelievably high temperature that can turn the gas inside the core of a star into plasma.

Please note that the plasma is the fourth state of the matter besides solid, liquid and gas. It is characterized by the separation of atomic components, instead of having a neutral corpuscle that is electrically neutral, the electrons are ripped apart from the positive ion composed of neutrons and protons which makes the cloud electrically conductive. 

The plasma can be used in plasma light: by heating the mercury gas, for example, a plasma form which conducts electricity and gives us light.

But on the scale of stars, the excessive temperature induced by the excessive pressure and gravitational forces in the core makes the positive ion in a furious motion state. The accelerated positive ions are accelerated sufficiently enough to crash into each other defying the repulsive coulomb forces of two atoms handling the same sign of electric charge.

The shock then merges the two particles together releasing a huge amount of energy due to the interplay of two opposing forces which are the Colomb repulsive force and the nuclear force.

Is it possible then to create an artificial nuclear fusion?

Hell no, at least for the moment, and unless, somehow, we manage to create a device that can attain 15 billion degrees and 265 billion bars which are respectively the temperature and pressure of the sun.

Seriously we don't need that much, we aren't going to recreate the sun but surely the biggest fear of humanity is the cost of such a project, it would be a gamble of billions of dollars and maybe even if we manage to work the reaction it won't be generating energy enough to recover the cost of the procedure. This is why investing the money in other sources of renewable energy that have already proven their efficiency may be a better choice.
