Hsu: Inefficient laser heating puts inertial fusion further from wall-plug gain
“Even though they, they're both at the point of 70% of the input energy, the efficiency of tokamak heating is much higher than the efficiency of the laser. So you have a longer ways to go to get true wall plug gain, which is ultimately what you need.”

Von Munch: Pacific Fusion avoids laser energy losses via direct pulsed current
“So instead of using a capacitor bank to charge a laser and a laser to drive a target, we use a capacitor bank to make a large electrical current. That electric current squishes the target, and that's a whole lot more efficient because you don't have this lossy…”
