Mirage of Fusion Power
Mirage of Fusion Power: _ “We say that we will put the Sun into a box. The idea is pretty. The problem is, we don’t know how to make the box”. Pierre-Gilles de Gennes _ Figure above shows ITER fusion reactor tokamak. A tokamak is a device used in nuclear fusion research for magnetic confinement of plasma. It consists of a complex system of magnetic fields that confine the plasma of reactive charged particles in a hollow, doughnut-shaped container. The tokamak (an acronym from the Russian words for toroidal magnetic confinement) was developed in the mid-1960s by Soviet plasma physicists. It produces the highest plasma temperatures, densities, and confinement durations of any confinement device. Fusion energy scientists believe that tokamaks are the leading plasma confinement concept for future fusion power plants. _____ Section-1 Prologue: The demand for energy is ever growing, as more people around the […]
