Fusion energy learning path
Move from simple particle ideas to reactor engineering, fuel cycles, power conversion, economics, and research frontiers.
Level 1Foundation
Atoms, isotopes, plasma, temperature, density, confinement, and why fusion is hard even though the reaction is simple to describe.
Level 2Reactor concepts
Tokamaks, stellarators, inertial confinement, magnetized-target fusion, field-reversed configurations, and z-pinch approaches.
Level 3Power plant systems
Blankets, tritium breeding, neutron damage, superconducting magnets, heat loops, turbines, maintenance, and regulation.
Level 4Fuel strategy
Compare D-T, D-D, D-He3, and p-B11 by ignition difficulty, neutron output, fuel availability, and conversion potential.
Level 5Commercial readiness
Read milestones carefully: net energy, wall-plug efficiency, duty cycle, materials lifetime, tritium inventory, and grid cost.
PracticeUse the 3D simulator
Change fuel, temperature, density, and magnetic field strength to see how gain and stress move together.
How to study fusion without getting lost
Start by separating the physics question from the engineering question. Physics asks whether the plasma can produce more energy than it loses. Engineering asks whether a complete plant can operate repeatedly, safely, affordably, and with maintainable hardware.
When you read a new milestone, ask four questions: What fuel was used? Was the energy measured at the plasma, target, device, or wall-plug level? How long did the pulse last? What system still needs to be built around it?
