And it's actually because if you want to make an energy source out of thisβ¦
So this had a gain of around 1.5, that namely the fusion energy was approximately 1.5 times the laser input energy.
Okay, this is a fairly significant threshold.
However, from the science of what I just told you, is that there's two fundamental efficiencies which come into it, which really come from physics, really.
One of them is hydrodynamic efficiency.
What I mean by this is that it's a rocket.
So this just has a fundamental...
efficiency built into it, which comes out to orders of like 10%.
So this means is that your ability to do work on the system is just limited by that, okay?
And then the other one is the efficiency of laser systems themselves, which if their wall plug efficiency is 10%, you've done spectacularly well.
In fact, the wall plug efficiency of the ones using that experiment are like more like 1%, right?
So when you go through all of this, the approximate, you know, place that you're ordering this is for a fusion power plant would be a gain of 100, not 1.5.
So you still, you know, and hopefully we see experiments that keep climbing up towards higher and higher gain.
But then the whole fusion power plant is a totally different thing.
So it's not one BB and one laser pulse per day.
It's like five or ten times per second, right?
Like that, right?
So you're doing it there.
And then comes the other aspect.
So it's making the targets, delivering them, being able to repeatedly get them to burn.
