Fusion is the process that powers the sun and other stars. It involves combining light atomic nuclei, like hydrogen, into heavier nuclei, like helium. This reaction releases an immense amount of energy, much greater than that produced by conventional nuclear fission.

Key Differences Between Fusion and Fission:

• Fuel: Fusion utilizes readily available isotopes of hydrogen, like deuterium and tritium, while fission relies on heavy elements like uranium or plutonium.
• Byproducts: Fusion produces relatively harmless helium, whereas fission generates radioactive waste that requires long-term storage.
• Chain Reactions: Fusion reactions are self-sustaining, requiring continuous energy input, while fission reactions can become uncontrollable, leading to potential meltdowns.

The Challenge of Achieving Fusion:

The sun achieves fusion at millions of degrees Celsius due to its immense gravity. On Earth, replicating these extreme conditions requires sophisticated technology. Achieving sustained fusion requires overcoming several hurdles:

• Temperature: Reaching and maintaining temperatures in the range of 100 million degrees Celsius is essential for fusion reactions to occur.
• Confinement: Keeping the hot, ionized fuel (plasma) confined within a magnetic field is crucial to prevent energy loss.
• Fuel Delivery: Injecting and maintaining a constant supply of fuel into the reaction chamber is critical for sustained fusion.

Current Approaches to Fusion Power

Researchers are pursuing diverse approaches to achieving controlled fusion, each with its own advantages and disadvantages:

1. Magnetic Confinement Fusion:

• Principle: Using magnetic fields to confine the hot plasma, preventing it from touching the reactor walls and losing energy.
