May 28, 2020. The SPARC design, though about the twice the size as MIT's now-retired Alcator C-Mod experiment and similar to several other research fusion reactors currently in operation, would be far more powerful, achieving fusion performance comparable to that expected in the much larger ITER reactor being built in France by an international consortium. The new set of papers represents the first time that the underlying physics basis for the SPARC machine has been outlined in detail in peer-reviewed publications. Many of the fine details are still being worked out on the machine design, covering the best ways of getting energy and fuel into the device, getting the power out, dealing with any sudden thermal or power transients, and how and where to measure key parameters in order to monitor the machine's operation. Plus almost free energy would eliminate poverty. Redundancy enables continuous operations. The estimated cost of an ARC reactor that matched the ITER-predicted performance was only a few billion dollars—as little as a tenth of ITER’s price tag. The large multi-institutional team of researchers represented in the new set of papers aimed to bring the best consensus tools to the SPARC machine design to increase confidence it will achieve its mission.
