Bypassing Carnot: the Direct Energy Conversion mandate
Editorial Board: if fusion is to undercut fission, the reactor must be a native electrical device — not a 19th-century boiler.

Material Embrittlement: The Hidden OpEx Destroying D-T Commercial Models
Editorial Board: 14.1 MeV neutrons systematically destroy reactor steel. Any LCOE model ignoring remote-handled rebuilds is fiction.

Engineering
The Stellarator Renaissance: Can 3D Coils Ever Be Manufactured at Scale?
Editorial Board: elegant physics, catastrophic manufacturing. The winner in the 2030s will be the machine that can be mass-produced.

Negative Triangularity: Eradicating ELMs by Reversing the D-Shape
Editorial Board: H-mode with positive triangularity is operational suicide. ELM-free negative triangularity must become the standard.

Vertical Displacement Events (VDEs) in Highly Elongated (κ>2.5) Plasmas
Editorial Board: high elongation without sub-millisecond control is not a reactor—it is a self-destructing physics experiment.

The Artificial Intelligence Mandate: Why Sub-Millisecond Control Loops Are Non-Negotiable
Editorial Board: in the 2030s, the software is the ultimate confinement field. PID controllers will not save a high-beta plasma.

Engineering
Ignition vs. Steady-State: The Flawed Focus on Q-Factor over Wall-Plug Efficiency
Editorial Board: Qplasma > 1 is the entry ticket, not the finish line. Without direct energy conversion, even Q > 20 cannot beat the Carnot limit.

The 30-Tesla Threshold: Pushing REBCO Beyond Safe Engineering Limits
Editorial Board: B4 scaling is seductive, but B2 Lorentz forces will crush standard Hastelloy substrates. 30 T demands MP35N and carbon-fiber over-banding.

Quench Protection in High-Temperature Superconductors: The Vanadium-Oxide Solution
Editorial Board: HTS quenches propagate at millimeters per second. Active voltage-tap dumping is too slow; passive VOx smart insulation is the only viable path.

Engineering
Structural Strain Management: MP35N Substrates and the 0.4% Delamination Cliff
Editorial Board: the difference between a failed startup and a power plant is managing micro-strain at 20 Kelvin. Hastelloy will not survive >30 T.

Engineering
Cryogenic Realities: 20K Closed-Loop Systems and Balance-of-Plant Parasitic Drains
Editorial Board: a 20K magnet is only viable if its cryoplant doesn't consume half the electricity produced. Neutron-free operation slashes parasitic loads.

Engineering
No-Insulation (NI) Coil Architectures: Current Sharing as a Double-Edged Sword
Editorial Board: bare-metal NI coils are a lab trick, not a grid backbone. Smart insulation—VOx layers—is the only viable commercial path.
