The Tokamak Fusion Reactor
The Tokamak method for inducing fusion reactions is the most promising method for the future of fusion energy. A Tokamak consists of a torus shaped vacuum chamber surrounded by high powered electromagnets. Helical magnetic field lines are required to maintain a stable fusion equilibrium (which is necessary for fusion to occur). To create these helical magnetic field lines, toroidal and poloidal magnetic fields must be combined. The toroidal field is created by placing a current through the conductive plasma within the chamber and the poloidal field is created by the high power electromagnets surrounding the torus.
In order to build a small demonstration Tokamak, I would need to figure out how to confine the plasma within an area much smaller than that used in a fully functional and full sized Tokamak, which is much harder to do than I first thought.
For more information on Tokamaks, look up the ITER project.
