The Potential of Nuclear Fusion: A Clean and Abundant Energy Source

TLDRNuclear fusion holds the promise of a clean, safe, and abundant energy source that can revolutionize society. By combining smaller elements, we can release a tremendous amount of energy. However, achieving fusion is challenging due to the electromagnetic repulsion that pushes atoms apart. To overcome this, plasma is used, which can be manipulated by a magnetic field. Deuterium and tritium are the key fuels for fusion reactions, as they have a high probability of creating helium and releasing energy. Deuterium is fairly common, while tritium is rare. To address the tritium scarcity, high energy neutrons can split lithium into tritium and helium. A blanket around the fusion chamber is used to capture high energy neutrons and breed tritium. The design of this blanket is crucial, as it also converts fusion energy into heat. Beryllium is a leading candidate for the blanket material due to its neutron multiplying properties and low tritium retention. However, beryllium is expensive and can become radioactive. One company, Helion, is taking a different approach to fusion by eliminating the need for costly beryllium blankets and developing a method to produce fuel on-site. They are also using a unique magnetic confinement method. Despite the potential of fusion, cost remains a major challenge for both fission and fusion reactors.
