sonoluminescence - nuclear fusion

Atoms are built out of three main particles: protons and neutrons—which make up the atomic nucleus—and electrons, the negatively charged particles that swarm around the nucleus and help atoms bond to one another to form molecules.

Most of the energy we use, such as burning gasoline, comes from chemical reactions. These involve the electrons and breaking or making the chemical bonds they form.

But the real juice is in the nucleus. These kinds of interactions, of atomic nuclei fusing together or splitting apart, are millions of times more potent than mere chemical reactions. In a nuclear reaction, a part of the mass of the neutron turns into energy, and the energies released are a million times those of mere chemical reactions. Chemical energy will move your car well enough. It is fusion energy that drives the stars.
