Laser-driven inertial confinement fusion is a multi-physics project aiming on efficient and sustainable energy production. It is involving phenomena on different spatial and temporal scales, ranging from macroscopic scales of several millimeters and nanoseconds, corresponding to the fusion target size and the whole time of the process, to the picosecond time scales, corresponding to the energy transport by charged particles and down to femtosecond times and sub-micron scales, where electromagnetic and nuclear processes dominate. A good comprehension of each of these processes and their interactions is indispensable for controlling the fusion reactions and producing commercially usable energy. In this presentation, I will recall the basic ideas of the inertial fusion, describe the physics at each temporal and spatial scale and discuss the present day developments and results with a critical analysis of unresolved issues and problems concerning the macroscopic and microscopic physics. I will conclude with a comparison of mainstream and alternative approaches to inertial fusion, their successes and challenges.
