  • New Fusion Record Achieved in Tungsten-Encased Reactor

    New Fusion Record Achieved in Tungsten-Encased Reactor

    A tokamak in New Jersey set a new record in fusion plasma by encasing its reaction in tungsten, a heat-resistant metal that allows physicists to sustain hot plasmas for longer, and at higher energies and densities than carbon tokamaks. A tokamak is a torus- (doughnut-) shaped fusion device that confines plasma using magnetic fields, allowing…


  • Japan Debuts Six-Story Experimental Fusion Reactor

    Japan Debuts Six-Story Experimental Fusion Reactor

    The biggest experimental nuclear fusion reactor in operation was inaugurated north of Tokyo today, as scientists continue to plug away at making nuclear fusion a viable source of the world’s energy. The reactor—JT-60SA—is a tokamak, a doughnut-shaped reactor that can heat plasma to 360 million degrees Fahrenheit (200 million degrees Celsius). The reactor fired up…


  • Will Nuclear Fusion Ever Power the World?

    Will Nuclear Fusion Ever Power the World?

    Only an unusually naive child, or a fossil fuel executive, could sincerely argue that our current energy situation is sustainable. For over 50 years now, well before the scope of the climate crisis was clear, scientists have been working toward an alternative: fusion power (i.e., using the heat from nuclear fusion reactions to generate electricity).…

    MIT Receives Millions To Build Fusion Power Plant Within 15 Years

    Nuclear fusion is like a way-more-efficient version of solar power – except instead of harnessing energy from the rays of a distant sun, scientists create miniature suns in power plants here on Earth. It would be vastly more efficient, and more importantly, much cleaner, than current methods of energy production. The main issue is that…
