The achievement is another key step — albeit in a journey that may take decades to complete — in the quest for an unlimited source of cheap and clean power.
.” While nuclear power produces bountiful clean energy, it has long drawn concerns over safety, though it is getting renewed attention amid an international push to reduce greenhouse gas emissions and slow global warming.
Fusion, on the other hand, creates energy by merging atoms together. It’s long been a dream because it could create limitless clean energy without the radioactive byproducts of nuclear power or the risk of meltdown. Plus, the fuel to make fusion happen is simply heavy hydrogen atoms, which can be found in something that Earth has in abundance: seawater. No mining of uranium is required.
