Documentary Description
Professor Brian Cox takes a global journey in search of the energy
source of the future. Called nuclear fusion, it is the process that
fuels the sun and every other star in the universe. Yet despite over
five decades of effort, scientists have been unable to get even a
single watt of fusion electricity onto the grid.
Brian returns to Horizon to find out why. Granted extraordinary
access to the biggest and most ambitious fusion experiments on the
planet, Brian travels to the USA to see a high security fusion bomb
testing facility in action and is given a tour of the world's most
powerful laser. In South Korea, he clambers inside the reaction chamber
of K-Star, the world's first super-cooled, super-conducting fusion
reactor where the fate of future fusion research will be decided.
