How fusion works?

Engineering, Fusion, Physics, Popular

The energy of a nucleus can be tapped in two ways: by splitting large nuclei into smaller ones (fission) or by combining small nuclei into larger ones (fusion). The first method yields atomic or nuclear (fission) energy, while the second provides fusion energy, which is essentially stellar power. This is the way the sun and…
