And just to circle back to it, when we talked about fusion, we talked about it had to be hot enough and it had to be dense enough.

And that's N and that's T. So now I have a very clear equation between magnetic field and density and temperature of the fusion fuel.

And that's really critical.

All plasmas have some, all fusion plasmas have some beta, some number.

The FRC has one of the highest betas, beta equal one.

However, what you also learn in school when you learn about beta the first time is you learn that high beta plasmas are typically unstable.

And so the good way to think about this is a tokamak is an accelerator are stable because those plasmas that are going around in the donut, there's a force on that donut.

But that plasma donut is very well held by all those magnetic fields, by all those magnetic coils.

If it tried to move,

it would be confined by that magnetic coil.

But in an FRC, it's unconfined.

So the plasma is confined, but the whole topology can do something what is called tilt.

Is that this whole plasma donut, because it's under pressure, can just turn over.

The way I think about this is, think about the...

A motor is a good example.

An armature, in the center of your motor, you have a spinning armature.

You have this spinning magnet on the inside, and it is held by the main axis of the magnet.

It can't go anywhere.

We don't have that axis.

We don't have any mechanical things inside these fusion systems.
