Direct drive is a method used in fusion energy research where energy is delivered directly to the fusion fuel via high-energy laser beams or ion beams. This approach focuses on compressing and heating the fuel to the necessary conditions for nuclear fusion to occur, aiming for a more efficient energy transfer process. The effectiveness of direct drive is enhanced through techniques such as spherical symmetry and precise timing of the energy delivery, which are crucial for achieving the extreme temperatures and pressures required for fusion.
