NUCLEAR FUSION
Nuclear energy…
Nuclear energy…
Is energy released from an atoms nucleus
You can release this energy in two different ways

NUCLEAR FUSION
LETS TALK ABOUT NUCLEAR FUSION
Unlike nuclear fission,
Nuclear fusion is the bonding/fusion of an atoms nucleus
It occurs NATURALLY in stars
It can also be reenacted in machines called…
It can also be reenacted in machines called…
FUSION REACTORS
But how do they work
Nuclear energy can also be released by the fusion of two light
elements
Unlike nuclear fission,
there is no limit to the amount of
fusion that can occur
Fusion reactors are now in experimental stages
at several laboratories in the United States,
at several laboratories in the United States,
and around the world

In nuclear fusion
you get energy when two atoms join together to form
one
1+1=1
In a fusion reactor
In a fusion reactor
hydrogen atoms come together to form helium atoms
In a fusion reactor
hydrogen atoms come together to form helium atoms
neutrons
In a fusion reactor
hydrogen atoms come together to form helium atoms
neutrons
and vast amounts of energy
It's the same type of reaction that powers hydrogen bombs
and the sun
What are the risks of nuclear fusion?
To run a fusion reactor you need little radioactive fuel (tritium)…
And therefore there is a very low loss of radioactivity
So the harm it would do to people and the environment…
Is much less than the harm done by nuclear fission
This would be a cleaner, safer, more efficient and more abundant source of
power than nuclear fission
Unfortunately we don’t have the technology to efficiently use them
YET
Today to create energy with renewable rescources we use
WIND
WIND HEAT
WIND HEAT
WATER
WIND HEAT
WATERSUN
These are the sources of the energy
To create the energy we use power plants like
WIND MILLS
VOLCANOES
DAMS
SOLAR PANELS
The advantages to using renewable rescources instead of fossil fuels
Is that they are cleaner and in infinite amounts
Nuclear fusion is an example of renewable energy
But since we don’t have fusion reactors, yet, we use other rescources
To produce the energy the source must go through a power plant
Renewable rescource power plants all work in a similar way
with slight variations from source to source
Let’s take wind as an example
The power plants for wind are windmills
The blowing wind turns the windmill, which turns the turbine attached to a
generator
The generator turns the kinetic energy into electrical energy that then is used
everyday
In conclusion…
We can say that we are soon to have fusion reactors
But for the time being
But for the time being
We can, and will, use what we have
