Matt Beall Podcast
Ashton Forbes | Orbs, Fusion Technology, & the Missing General

And I would slightly disagree.

Matt Beall Podcast
Ashton Forbes | Orbs, Fusion Technology, & the Missing General

I think there is something in there, but I think that that idea is still mostly true, is that if you look at the most common popular fusion reactors right now,

Matt Beall Podcast

The most popular one is a tokamak, and tokamaks are completely junk physics, junk fusion, if it comes to that.

Matt Beall Podcast
Ashton Forbes | Orbs, Fusion Technology, & the Missing General

The guy that invented the tokamak said that, actually.

Matt Beall Podcast
Ashton Forbes | Orbs, Fusion Technology, & the Missing General

He said that Robert Boussard went to a Google TED Talk, and he said...

One of the top theorists in nuclear physics who helped develop the tokamak said, the only thing we learned about tokamaks is they're no damn good.

Matt Beall Podcast
Ashton Forbes | Orbs, Fusion Technology, & the Missing General

No damn good at all.

Matt Beall Podcast
Ashton Forbes | Orbs, Fusion Technology, & the Missing General

And the reason why they're no damn good is because of something called beta.

Matt Beall Podcast
Ashton Forbes | Orbs, Fusion Technology, & the Missing General

Beta is a measure of the efficiency of the use of the magnetic field.

Matt Beall Podcast
Ashton Forbes | Orbs, Fusion Technology, & the Missing General

So we take a magnet and we're trying to make a fusion reactor out of the magnet.

Matt Beall Podcast
Ashton Forbes | Orbs, Fusion Technology, & the Missing General

The beta is how much of the magnetic field we're using.

Matt Beall Podcast
Ashton Forbes | Orbs, Fusion Technology, & the Missing General

So for tokamaks, it's about 10%.

Matt Beall Podcast
Ashton Forbes | Orbs, Fusion Technology, & the Missing General

So of all that magnetic field we're using, we're only really using about 10% of it.

For plasmoid research, which is the heart of field reverse configuration, if you look up helium fusion, tri-alpha energy, a lot of the prominent fusion companies, including the one that Donald Trump just purchased, tri-alpha energy, they do something called field reverse configuration, which uses a plasmoid at the center of it.

This is what Bob Greener talks about all the time, which is a natural instability in plasma that knots itself up and becomes stable.

Matt Beall Podcast
Ashton Forbes | Orbs, Fusion Technology, & the Missing General

So like a shape that is unstable that becomes stable and leads to stability and confinement far higher than physics can explain.

Matt Beall Podcast
Ashton Forbes | Orbs, Fusion Technology, & the Missing General

So these plasmoids have a high beta regime.

Matt Beall Podcast
Ashton Forbes | Orbs, Fusion Technology, & the Missing General

Their beta is roughly 100%.

Matt Beall Podcast
Ashton Forbes | Orbs, Fusion Technology, & the Missing General

This means that using the exact same magnets that the tokamaks use, if you use a different configuration, a field reverse configuration,

they're roughly 10 times more efficient using the same exact magnets.
