The world’s largest and most powerful superconducting electromagnet is ready to become the pulsing “heart” inside of a massive tokamak nuclear fusion reactor. Once assembled, the installation will be strong enough to lift a 112,000-ton aircraft carrier, or about 10 monster trucks. At that point, the plasma’s atomic nuclei begin to combine (hence “nuclear fusion”), in the process releasing unprecedented amounts of heat that can then hypothetically be used to provide limitless, clean energy to the masses. ITER engineers expect their tokamak reactor to generate 500 megawatts (Mw) of fusion power using just 50 Mw of input heating–compared with a nuclear fission reactor’s roughly 1,000 Mw of power output from an input of 3000 Mw . Even so, Barabaschi remains hopeful about the tokamak reactor’s potential, as well as what it represents on a global scale.
