ITER is the international fusion reaction reaction, its being built over the next 8 years in the south of france, and should hold
a mixture of tritium and deutrium gases at a hot enough temperature and high enough pressure to generate more fusion power
output than the electricity need to create the plasma, ITER should run consistantly in the breakeven range of fusion power.
That said, scientists and not created a system for extracting the energy from the plasma yet, and true energy generation
is left from the next reactor after ITER, currently called DEMO, which should demonstrate useful power generation to the
electricity grid. ITER is the successor to JET the joint european torus which was the first reaction to show breakeven
energy generation.
