There are two ways to achieve the temperatures and pressures necessary for hydrogen fusion to take place:
- Magnetic confinement uses magnetic and electric fields to heat and squeeze the hydrogen plasma. The ITER project in France is using this method.
- Inertial confinement uses laser beams or ion beams to squeeze and heat the hydrogen plasma. Scientists are studying this experimental approach at theNational Ignition Facility of Lawrence Livermore Laboratory in the United States.
