The Tokamak Fusion reactor

In my series I rely upon the tokamak fusion reactor for power. According to the US Department of Energy:

A tokamak is a machine that confines a plasma using magnetic fields in a donut shape that scientists call a torus. Fusion energy scientists believe that tokamaks are the leading plasma confinement concept for future fusion power plants. In a tokamak, magnetic field coils confine plasma particles to allow the plasma to achieve the conditions necessary for fusion. One set of magnetic coils generates an intense “toroidal” field, directed the long way around the torus. A central solenoid (a magnet that carries electric current) creates a second magnetic field directed along the “poloidal” direction, the short way around the torus. The two field components result in a twisted magnetic field that confines the particles in the plasma. A third set of field coils generates an outer poloidal field that shapes and positions the plasma.

I copied this verbatim because it is the clearest explanation. They wrote the statement above using tax money, and as a tax payer, I believe I can copy it since I own at least a bit of it. 

Many believe it is the energy supply of the future. The first one began operating in the USSR (current day Russia), in 1958. Scientists have therefore been working on it for sixty-five years. 

I use paired tokamaks because I believe it will be easier, and safer, to refuel them alternately. I, of course, am guessing, but since no one else has made one function continuously, who knows? I might just be right. (And am most likely wrong).
