Minimal waste: Produces negligible radioactive waste compared to fission.
High energy yield: Potentially more efficient than traditional nuclear and fossil fuel sources.

Current Challenges

Despite the promise, harnessing fusion energy presents significant challenges. The primary obstacle is efficiently converting the energy released from fusion reactions into usable electricity. Traditional methods, such as heating water to spin steam turbines, suffer from substantial energy losses, with efficiencies often capped at around 60%.

Common Issues:

Energy conversion inefficiencies: Losses in heat transfer and mechanical energy conversion.
High operational temperatures: Fusion requires extremely high temperatures to sustain reactions, complicating material and engineering requirements.
