Abstract: An inertial confinement fusion (ICF) system includes a target that is imploded by a driver having at least one laser source. The target includes a fusion fuel layer, an ablator layer, and a corona-forming layer. At least one laser source is configured to illuminate the target with two substantially opposed beams in two or more stages. Such illumination results in ignition of the fusion fuel layer. Other embodiments are described and claimed.

Abstract: The specification discloses a robot for inspection adapted to travel virtually unlimited distances through small-diameter enclosed spaces such as conduits or ducts, preferably using a fluid-driven screw-drive propulsion system. The robot preferably includes a drive module having a plurality of wheels inclined at an angle greater than zero degrees and less than ninety degrees to the longitudinal axis of the pipe, a driver module having a plurality of wheels aligned parallel to the longitudinal axis of the pipe, and a power module. The driver module is preferably connected to the drive module such that the drive and driver modules are capable of providing the locomotive motion of the robot. The power module preferably provides the power to the drive and driver modules.
