Barring a catastrophic decline in population, the world will need a new power source in the next century. Given projected increases in demand for power, and without the introduction of a major new power source, oil and coal reserves are likely to be at or near exhaustion within 100 years. Furthermore, the use of these fuels has undesirable environmental consequences. The supply of fuel for conventional nuclear fission power plants is also limited, although fission "breeder" reactors could ease this limitation. However, nuclear fission has its own undesirable consequences, including radioactive waste buildup and potential contribution to the proliferation of nuclear weapons.vbcrlf Many scientists believe controlled fusion is the long-term answe...
. . .
.... For instance, magnetized targets may relax the performance requirements (and hence the cost) for any ICF driver, such as lasers or particle beams; and plasma configurations developed in magnetic confinement research may lead to optimal magnetized target plasmas. The last word on controlled fusion power has not yet been written, and a diversity of ideas would seem beneficial at this point. vbcrlf
