Question:
How many different types of fusion reactors have been developed?
Replies:
The main categories of fusion reactors are magnetic confinement and inertial
confinement, and each category includes several types of reactors. Most work
done today focuses on Tokamaks (one of the magnetic confinement reactors) or
laser ignition (inertial confinement). The ITER project being built in France
is a Tokamak, while the National Ignition Facility that is just coming into
operation at Lawrence Livermore National Laboratory is a laser ignition facility.
The Wikipedia article on Fusion Reactors
http://en.wikipedia.org/wiki/Fusion_reactor
has a nice summary of the history of the various types of fusion devices
that have been considered since the mid-twentieth century and also a good table
categorizing these devices.
