A burst of interest
Fusion energy is appealing for various reasons, the most important being its inherent safety. The fusion reaction requires a large amount of energy to begin. As a result, stopping a fusion reaction is as simple as turning off the initial energy source, eliminating the risk of runaway reactions, which is a significant difference from fission. Furthermore, fusion is sustainable because we have the know-how to produce the necessary fuel without causing environmental damage, explains Ma. Approximately one out of every 10,000 particles in seawater is deuterium oxide (D2O) rather than regular water. While tritium requires breeding, she says we have perfected its production techniques.
