在这部地平线系列：人造恒星可能吗？片中,Brian Cox 教授進行一次全球旅行去尋找未來能量來源. 稱作「核聚變」,給太陽和宇宙中其他星球提供燃料. 儘管超過50年的努力，科學家們還是不能夠成功地利用聚變發電到電網...
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.
把复杂的事情简单化，才是真正的智者。科学传播的效应。核聚变的可能。科技双刃剑与科学的短处。
