Nuclear fusion, the process that powers every star in the observable universe, has moved from theoretical physics into the realm of real laboratory results. On December 5, 2022, scientists achieved ...

Robert Adams updated the work on a phase 2 Pulsed Fission-Fusion (PuFF) Propulsion Concept. Robert works at the NASA Marshall Space Flight Center. This system should be able to achieve 15 kW/kg and 30 ...

Energy efficiency in physics is not measured the way most people think about it. Instead of asking how much heat a process ...

Clean and sustainable nuclear energy may sound like a washed up, post-war dream, but the modern reality of this power source is much more complicated. For one, nuclear energy in the coming decades ...

Matthew Hole receives funding from the Australian government through the Australian Research Council and the Australian Nuclear Science and Technology Organisation (ANSTO), and the Simons Foundation.

They are extending concepts and experiments in pulse power studied at Sandia National Labs. The Sandia Z Machine used currents of about 26 million amps to reach peak X-ray emissions of 350 terawatts ...

If climate change is an 'existential threat to human existence,' as President Biden suggests, nuclear power may have to be part of the transition from fossil fuels. The Bill Gates-backed TerraPower ...

At the same time, a current of cold electrons travels toward the heated plasma from the opposite direction. When the two meet, the plasma develops filament-shaped instabilities that SLAC’s facilities ...

When one thinks of nuclear power, thoughts often include nuclear fission weapons (AKA atomic bombs) and their dangerous consequences. However, new research in sustainable energy production indicates ...

More than 110 countries and countless companies have pledged to reach net-zero emissions by 2050, but can they get there with existing technologies? Probably not. But the net-zero equation is complex.

Nuclear fusion combines light hydrogen atoms to release energy, similar to the sun's processes. Fusion reactors are inherently safe as they cannot melt down, unlike fission reactors. Achieving ...
