Could we build a miniature sun on Earth? [Science Video]

Stars have cores hot and dense enough to force atomic nuclei together, forming larger, heavier nuclei in a process known as fusion. In this process, the mass of the end products is slightly less than the mass of the initial atoms. But that “lost” mass doesn’t disappear — it’s converted to energy … a lot of energy.

Explore the possibility of nuclear fusion technology to create limitless, on-demand energy with almost no emissions.
