WE KNOW
THAT TWO TYPES
OF NUCLEAR
REACTIONS EXIST:
FUSION & FISSION

FUSION IS AN
ENERGY SOURCE
 
The resulting atom is lighter
than the initial ones. Where
has the mass gone?
It is converted into 
energy
,
according to the famous
equation from Albert Einstein:
E=mc

In other words:
Energy = mass x speed of
light squared

FUSION WORKS
 
The sun and the stars shine
thanks to fusion reactions
taking place in their core.

HOW CAN WE DO
THE SAME ON
EARTH?
 
The Sun fuses Hydrogen (H)
nuclei into Helium (He).
On Earth, the most efficient
approach is to use two
isotopes of Hydrogen:
•  Deuterium (D)
•  Tritium (T)
