The energy potential locked in the oceans via deuterium is effectively limitless on a human timescale. The difficulty of maintaining the required temperatures and confining the plasma with magnetic fields is the current barrier, not a theoretical flaw in the process.
Fusion Versus Fission Energy Output: Understanding the Yield Difference
While both processes release energy by altering the nucleus of an atom, the underlying mechanics and outcomes are vastly different. The goal is not merely to replicate the sun’s power on Earth, but to harness a clean, dense, and universally accessible energy source.
The energy yield per unit mass of fuel is significantly higher in fusion. This splitting releases a significant amount of energy in the form of heat, along with additional neutrons that can trigger a chain reaction.
Fusion Versus Fission Energy Output: Why Fusion Delivers Higher Yield
This "lost" mass is converted directly into energy. There is no risk of a fusion bomb-style explosion.
