Nuclear fusion, may be the answer.
But, if the technology for nuclear fusion is so hard to achieve,
why is it believed to have potentials worthy of developments?
The Sun is huge,
the gravitational force is strong,
with extremely pressure,
which forced atoms to combine.
Hydrogen atoms are essentially protons,
and protons repel one another
because they all carry a positive charge.
But the gravitational force is so strong,
forcing them
to merge.
Take neutrons, or Helium for example:
Helium
has 2 protons and 2 neutrons.
In the process of merging,
it becomes a different element with a larger atomic structure,
this transformation,
is called “nuclear fusion.”
Nuclear fusion is much harder to achieve than fission.
Most people know that hydrogen bombs,
Are much more powerful
than atomic bombs.
Atomic bombs employ nuclear fission,
while hydrogen bombs employ nuclear fusion.
It's really difficult to be controlled,
and has been in R&D for over 50 years.
In the former Soviet Union, they have something called
the “Tokamak.”
It employs the use of coils,
making a huge magnetic field,
and turn
the atoms that would undergo nuclear fusions
into the form of plasma streams.
Because they all carry positive charges,
they could be controlled by the magnetic field,
packing them tightly together.
Triggered by a kind of shockwave,
nuclear fusion would occur,
but still,
it's difficult to maintain a stable energy flow.
Nuclear fusion may be a way out,
but since it's so hard to achieve absolute control,
why is it considered a high-potential investment?
One main reason is the rich in resources for it.
For every gallon of seawater,
about 8% of Deuterium could be extracted,
and Tritium could also be refined
from Lithium in rocks.
Neither the sea nor the rock would ever run out,
so the supply of
Deuterium and Tritium is endless.
