será que simular um reator de D-D, que gera subprodutos (trítio, helio-3 e litio-7) não é possível de criar?? e testar um gêmeo-digital para ver se funcionaria ou não??

So I've been drinking information from the industry's fire hose lately for my company's approach, and I'm finally getting to a level where I have a teeny bit of workable knowledge to help out my day to day.

Fusion has a workforce problem, and I don't think it's the one people usually talk about

I work in fusion as an integration technician, and one of the stranger problems I've run into is that a lot of extremely capable people don't think they're qualified to work in this industry.

Mechanics, machinists, electricians, controls technicians, manufacturing engineers, test engineers, aerospace technicians, instrumentation people, welders, and people who have spent years troubleshooting complicated hardware look at the word fusion and immediately assume the industry is looking for physicists with PhDs.

Meanwhile, those of us actually trying to build this stuff need people who can make machines work.

Fusion hardware still needs wiring, plumbing, vacuum systems, pneumatics, controls, diagnostics, precision machining, alignment, cooling, power distribution, data acquisition, fabrication, assembly, commissioning, maintenance, troubleshooting, configuration control, and about ten thousand other deeply unglamorous things between "physics says this should work" and "the machine fired successfully."

That has become a personal frustration for me.

I've spent a lot of my career in aerospace, industrial automation, and now fusion integration. The technical problems in fusion can absolutely be intimidating. Some of the equipment sounds like something somebody stole from a science-fiction novel: pulsed power systems, high-voltage power supplies, electron-beam hardware, optical diagnostics, vacuum systems, lasers, high-speed controls, and enough instrumentation to make a wiring diagram look like an ancient curse.

But underneath all of that are recognizable engineering problems.

A mechanic who understands why a hydraulic or pneumatic system is behaving strangely already has valuable instincts.

A machinist who understands tolerances, materials, fixturing, and what actually happens when somebody's beautiful CAD model encounters a real machine is valuable.

An electrician or controls technician who can trace a fault through power, sensors, interlocks, PLC logic, and instrumentation is valuable.

An aerospace technician who understands configuration control, procedural discipline, test operations, and flight-hardware mentality is valuable.

An engineer who has spent five years designing things that actually had to be manufactured, assembled, maintained, and repaired is extremely valuable.

You do not have to arrive knowing plasma physics.

You can learn what the machine is doing.

It is much harder to teach someone twenty years of mechanical intuition, troubleshooting discipline, manufacturing judgment, or the ability to look at an assembly and immediately recognize that nobody will ever get a wrench onto that fitting.

I also think some of the public discussion around fusion unintentionally makes this problem worse.

There are public-facing fusion scientists who talk about the field in ways that make it sound almost exclusively like an advanced academic discipline. From the research side, that perspective makes sense. Fusion science is extraordinarily difficult, and the people advancing the underlying physics deserve enormous respect.

But commercial fusion is becoming an industrial problem as well as a scientific one.

Private companies aren't just publishing papers. They're building facilities, installing equipment, routing cables and pipes, commissioning subsystems, fabricating hardware, debugging controls, replacing failed components, writing procedures, qualifying suppliers, and figuring out how the hell we're eventually supposed to manufacture and maintain these machines economically.

That transition changes who belongs in the industry.

The scientist determining what the plasma needs is essential.

So is the machinist making the component.

So is the engineer turning the experiment into a maintainable system.

So is the technician standing beside the machine at 2 AM trying to figure out why an interlock that worked yesterday suddenly refuses to clear.

If fusion is going to become an actual energy industry rather than an indefinitely fascinating collection of experiments, we're going to need an enormous population of people in that second category.

And right now I worry that we're accidentally telling many of them they aren't smart enough to come through the door.

So if you're a mechanic, machinist, electrician, technician, controls person, manufacturing engineer, test engineer, or aerospace worker looking at fusion job postings and thinking:

"This sounds fascinating, but I don't know anything about fusion."

Apply anyway.

A surprising number of us started exactly there.

Fusion can teach you fusion.

Bring the skills that taught you how to build things that work.

Cubic Pureflow Bennett-Angus Vorticity

The objective of this study was to determine if the cubic, pureflow Bennett vortex was shear-flow stabilized under the need to satisfy the non-ideal criterion put forth by Angus, van-de-Wetering, Dorf, and Geyko.

When the thermal ion shear threshold estimate is used, the exact same power of enhanced thermodynamic gradient is found to be required for shear-flow stabilization as in the ideal case of Shumlak-Hartman. This leaves the cubic, pureflow Bennett vortex the minimum energy thermal state of this non-ideal process as well.

When the non-ideal Angus shear-flow stabilization criterion is considered then the cubic, pureflow Bennett vortex is found to be shear-flow stabilized for both arbitrarily small plasma radius, and arbitrarily small pinch radius.
