Imagine if we manage to replicate and miniaturize the process taking place in the core of stars. This would not only provide us a low-cost, clean and virtually limitless source of energy, it would also end our unsustainable reliance on polluting fossil fuels.
In a recent paper published in the journal Nuclear Fusion, a team of physicists at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL), has detailed the design of a viable and efficient fusion device — one that already exists in an experimental form.
The spherical device, known as a “tokamak,” can contain high-energy, superheated plasma produced through nuclear fusion using relatively low and inexpensive magnetic fields. This, the researchers believe, makes it a leading candidate to complement the International Thermonuclear Experimental Reactor — a doughnut-shaped tokamak that 35 nations are building in France to demonstrate the feasibility of fusion power.
The PPPL tokamaks spherical, “cored apple” design also allows tritium — a rare hydrogen isotope — to be created,
