Scientists say they have cleared technical hurdle in fusion research. ‘Physicists working in the United States believe they have cracked an important problem facing man-made nuclear fusion, touted as the cheap, safe, clean and almost limitless energy source of the future. In fusion, atomic nuclei are fused together to release energy, as opposed to fission – the technique used for nuclear power and atomic bombs – where nuclei are split. In a fusion reactor, particles are rammed together to form a charged gas called a plasma, contained inside a doughnut-shaped chamber called a tokamak by powerful magnetic coils.’
Nuclear fusion plasma problem tackled. ‘Nuclear fusion could become a more viable energy solution with the discovery of way to prevent super-hot gases from causing damage within reactors.
$13 billion nuclear fusion site gets green light. ‘The International Thermonuclear Experimental Reactor, or ITER, is intended to show that nuclear fusion, which harnesses the same energy that heats the sun to generate electricity, can wean the world off pollution-producing fossil fuels. Nuclear fusion also produces no greenhouse gas emissions, which many scientists tie to global warming, and only low levels of radioactive waste.’
