What makes fusion interesting? For starters, because of it’s AWESOME power. Did you know there is enough energy inside one measly gram of hydrogen to power a 100 watt light bulb for well over 28,000 years?!
There’s four fundamental forces of nature: gravity, electromagnetism, weak nuclear, and strong nuclear. The strong nuclear force is what holds the neutrons and protons of an atom together and is the strongest of all the forces. Fusion energy literally taps into the amazing power inside the nucleus of atoms. It is a demonstration of Einstein’s famous E = mc2 equation. The only other conceivable energy source that could provide more energy is the annihilation of matter with antimatter, but that remains in the realm of science fiction.
