The text discusses nuclear fusion, a potential energy source that fuses light atomic nuclei, primarily isotopes of hydrogen, to produce energy. Unlike nuclear fission, fusion is still under research and not yet a viable energy source. The JET project in the UK and the ITER project in France are key experiments in developing fusion energy. Despite challenges, experts believe fusion could revolutionize energy production due to its low CO2 emissions and minimal radioactive waste. Teljes cikk (Euronews.com)
