How will a fusion power plant work? – Video clip
A school class in 2100: The futuristic lesson is backed up with documentary photos and animations and gives the viewer an entertaining survey of the principles, development and status of fusion research. Like the sun, a fusion power plant is to derive energy from fusion of atomic nuclei. To ignite the fusion fire one has to succeed in confining the fuel, a hydrogen plasma, in magnetic fields and heating it to temperatures of over 100 million degrees. The next step in world-wide fusion research on the way to this almost inexhaustible energy source is the ITER international test reactor.
