In a pulse system, researchers in pulsed magnetic fields have demonstrated over 100 Tesla magnetic fields in pulsed magnets.
That's much higher than you can get in a steady magnet or what's been demonstrated so far.
Not yet, but we need to because that's really important.
Okay.
And so we can even talk even a little bit further about how fusion scales.
And so in fusion, the hotter you get the fuel, the more fusion you get.
And we know that by increasing the magnetic field, B squared is in T.
You increase density and temperature together.
More density, more temperatures, more fusion, plus more temperatures, even more fusion.
And so what we see is that in these types of systems, a scaling very clearly of magnetic field to the 3.75 power, or even in a lot of demonstrations, 3.77, that specific scaling.
That's a very strong scaling of fusion power output.
Wow.
and fusion reactions.
And so that tells you you want to go to as maximum magnetic field as you can.
Pulse systems are really powerful.
Pulse systems have showed when you do pulsed magnetic fields compared to a steady magnetic field, researchers have shown over 100 Tesla magnetic fields, where in a steady system, people have showed in the 20, maybe high 20 Tesla systems.
And if it's B to the 3.77 power, already you can see massive fusion power outputs by doing a pulsed system.
But then I said pulsed, and pulsed already implies shorter tau.
And so that is, in the fusion field, the name of the game.
Folks will have a very inertial fusion, will have a nanosecond tau, very short, but then very high pressure.
