I keep getting lost in the numbers here. What was the net gain/loss for the entire system? Without the “lasers are 1% efficient at 20% energy loss with 40% energy transfer loss” and all that.
People are estimating how this result moves the equation for an overall system that is designed for power production. Most numbers I have seen still leave a theoretically optimal power plant producing around a 30% loss in power with this number.
While at it: I don't think the NIF approach will ever be applicable to commercial power generation on Earth. But I hope it will be one day applicable to a fusion-based rocket engine.
