Answer:
Ya some percents of chance to make arc reactor
The goal? To produce the world's smallest fusion reactor -- one that crushes a doughnut-shaped fusion reaction into a 3.3 meter radius -- three of which could power a city the size of Boston.
And MIT researchers are getting close to their goal, despite a recent cut in federal funding that could slow their progress.
The lessons already learned from MIT's smaller Alcator C-Mod fusion device have enabled researchers, including MIT Ph.D candidate Brandon Sorbom and PSFC Director Dennis Whyte, to develop the conceptual ARC (affordable, robust, compact) reactor.
"We wanted to produce something that could produce power, but be as small as possible," Sorbom said.
A working ARC fusion reactor would use 50 megawatts (MW) of power to produce 500MW of fusion power, 200MW of which could be delivered to the grid. That's enough to provide 200,000 people with electricity.

A look inside MIT's C-Mod, which is only 0.68 meters in radius -- the smallest fusion reactor with the strongest magnetic field in the world.
While three other fusion devices roughly the same size as the ARC have been built over the past 35 years, they didn't produce anywhere near its power. What sets MIT's reactor apart is its superconductor technology, which would enable it to create 50 times the power it actually draws. (MIT's PSFC last year published a paper on the prototype ARC reactor in the peer reviewed journal ScienceDirect.)
The ARC reactor's powerful magnets are modular, meaning they can be easily removed and the central vacuum vessel in which the fusion reaction occurs can be replaced quickly; besides allowing upgrades, a removable vessel means a single device could be used to test many vacuum vessel designs.
Fusion reactors work by super heating hydrogen gas in a vacuum, the fusing of hydrogen atoms form helium. Just as with splitting atoms in today's fission nuclear reactors, fusion releases energy. The challenge with fusion has been confining the plasma (electrically charged gas) while heating it with microwaves to temperatures hotter than the Sun.
Sustainable energy
The result of successfully building an ARC reactor would be a plentiful source of clean and reliable power, because the needed fuel -- hydrogen isotopes -- is in unlimited supply on Earth.
"What we've done is establish the scientific basis...for, in fact, showing there's a viable pathway forward in the science of the containment of this plasma to make net fusion energy -- eventually," Whyte said.
Fusion research today is at the threshold of exploring "burning plasma," through which the heat from the fusion reaction is confined within the plasma efficiently enough for the reaction to be sustained for long periods of time.

A look at the exterior of MIT's C-Mod nuclear fusion device. The C-Mod project has paved the way for a conceptual ARC reactor.
Normally, gas such as hydrogen is made up of neutral molecules bouncing around. When you superheat a gas, however, the electrons separate from the nuclei creating a soup of charged particles rattling around at high speeds. A magnetic field can then press those charged particles into a condensed shape, forcing them to fused together.
The 40-year conundrum of fusion power is that no one has been able to create a fusion reactor that puts out more power than is required to operate it. In other words, more power is required to keep the plasma hot and generating fusion power than the fusion power it produces.
Europe's working tokamak reactor named JET, holds the world's record for power creation; it generates 16MW of fusion power but requires 24MW of electricity to operate.
MIT's researchers, however, believe they have the answer to the net power problem and it'll be available in a relatively tiny package compared to today's nuclear fission power plants. By making the reactor smaller, it also makes it less expensive to build. Additionally, the ARC would be modular, allowing its many parts to be removed for repairs to upgrades, something not previously achieved.
What sets MIT's fusion device apart
What MIT alone has done is create the world's strongest magnetic containment field for a reactor its size. The higher the magnetic field, the greater the fusion reaction and the greater the power produced.
"We're highly confident that we will be able to show this medium can make more fusion power than it takes to keep it hot," Whyte said.
