"decouples fuel compression and ignition using low-energy inputs... potential to cut inertial fusion power plant costs 20X using existing/ proven technologies: lower capital costs with lower complexity/ core components, energy delivery system costing 1/10th capital cost, lower pulse rate enabled by high gain lowering operating costs... since pulsed system adjusts its output, it can also provide flexible, low-cost electricity to support modern grids which utilize high level of intermittent renewables... mid-2030s"
