And I would slightly disagree.
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,
The most popular one is a tokamak, and tokamaks are completely junk physics, junk fusion, if it comes to that.
The guy that invented the tokamak said that, actually.
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.
No damn good at all.
And the reason why they're no damn good is because of something called beta.
Beta is a measure of the efficiency of the use of the magnetic field.
So we take a magnet and we're trying to make a fusion reactor out of the magnet.
The beta is how much of the magnetic field we're using.
So for tokamaks, it's about 10%.
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.
So like a shape that is unstable that becomes stable and leads to stability and confinement far higher than physics can explain.
So these plasmoids have a high beta regime.
Their beta is roughly 100%.
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.
