What it is not a measure of how much energy you put into the system and what happens to that in terms of you started this campfire with a blowtorch.

What about all that blowtorch energy?

What are you getting for that?

And so I think that's something that high beta is one more measure

side benefit that it turns out is actually maybe the tail that wags the dog is that not only do you at high efficiency get out any of the new fusion energy, which is great because that's what you want, make electricity from fusion, but you also get to recover all of that magnetic energy you put back into it.

And that's the really powerful one.

And that's something that folks have demonstrated over 95% efficiency, that you can put electricity into fusion and then get that electricity back out at 95% efficiency and

plus some very high efficiency, maybe 80%, maybe higher, of all the fusion product electricity too.

So now you're just making a tremendous amount of electricity in one of these systems.

And that has all kinds of performance and engineering benefits that are really powerful.

But it also pushes you to other fuels.

Mm-hmm.

So we talked about how deuterium and tritium fuels make this neutron, which leaves the system to boil water, to run steam turbines, but it doesn't push back on the magnetic field.

So in one of these high beta systems, it's actually not a great fuel at all.

And so the other fuels that are out there are even more interesting.

And one of the candidate fuels that's really interesting is called deuterium and helium-3.

Now, we talked about deuterium, heavy hydrogen.

Well, helium-3, the nucleus is also called a helium.

That's why we named the company that, is light helium, which is a normal helium, which is what you find in a balloon.

It's two protons, two neutrons.
