The Levitated Dipole Experiment (LDX) reactor is housed inside a 16-foot-diameter steel structure in a building on the MIT campus that also houses MIT’s other fusion reactor, a tokamak called Alcator C-mod. Credit: LDX teamFrom Live Science:
Physicists may be one step closer to achieving a form of clean energy known as nuclear fusion, which is what happens deep inside the cores of stars.
A recent experiment with a giant levitating magnet was able to coax matter in the lab to extremely high densities — a necessary step for nuclear fusion.
When the density is high enough, atomic nuclei — the protons and neutrons of atoms — literally fuse together, creating a heavier element. And if the conditions are right that fusion can release loads of energy.
