How small can a tokamak be?
Using virtually identical physics and related theories, newer designs can bring the size WAY down. A spherical tokamak machine can be about 1/20 the size of ITER, and probably have nearly twice the output – especially if the heat generated can be used more efficiently in generating electricity.
How small can a fusion reactor be?
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.
Is a miniature arc reactor possible?
In short, yes. Teams at MIT are working to create a fusion reactor that would be about 21 feet in diameter. Nowhere near the size of Iron Man’s reactor, but still, a relatively small size compared to other power generation systems currently in use.
How big is a tokamak?
The Tokamak Building will be slightly taller than the Arc de Triomphe in Paris. Measuring 73 metres (60 metres above ground and 13 metres below), it will be the tallest structure on the ITER site.
Do arc reactors exist?
The Stark Arc Reactor is most likely a Multi-Isotope Radio-Decay Cell. This type of fusion reactor exists today at research pilot scale. The reactor pictured, ITER, is under construction and is planned to be the first fusion reactor large enough to produce a net gain of energy.
Is cold fusion possible?
Cold fusion is a hypothesized type of nuclear reaction that would occur at, or near, room temperature. There is currently no accepted theoretical model that would allow cold fusion to occur.
Is Lenr possible?
LENR can generate ideal energy Nuclear meltdown is not possible. Because the fuel is contained in ordinary water, the energy would be available to all countries and could be generated in each home or business. Such energy could not be interrupted by weather, terrorists, or political conflict.
What is a tokamak used for?
A tokamak (a Russian acronym for toroidal chamber with axial magnetic field) is a fusion device that uses a combination of electromagnets and electric currents to contain plasma, which is used to generate thermonuclear fusion power. Building has begun on a large fusion reactor by the international fusion project, ITER.
When will the largest tokamak in the world be built?
Cutaway diagram of the International Thermonuclear Experimental Reactor (ITER) the largest tokamak in the world, which began construction in 2013 and is projected to begin full operation in 2035. It is intended as a demonstration that a practical fusion reactor is possible, and will produce 500 megawatts of power.
What is the maximum power output of a tokamak?
, JET remains the record holder for fusion output, reaching 16 MW of output for 24 MW of input heating power. The word tokamak is a transliteration of the Russian word токамак, an acronym of either:
How do you heat up a plasma in a tokamak?
A gas can be heated by sudden compression. In the same way, the temperature of a plasma is increased if it is compressed rapidly by increasing the confining magnetic field. In a tokamak, this compression is achieved simply by moving the plasma into a region of higher magnetic field (i.e., radially inward).
