Chapter Summary:

​

• Promise vs physics: Fusion offers high energy yield and limited long‑lived waste, but needs extreme temperatures and net energy gain at viable cost.

• Big science, small startups: From ITER’s Tokamak to private firms (e.g., Helion, General Fusion, Tri Alpha) pursuing alternative fuels and compact reactors.

• Reality check: Experimental break‑even milestones are encouraging, but commercial ROI targets (≈20×) remain the hurdle.

• Takeaway: Fusion sits at the edge of hope and engineering—worth watching, not yet a grid solution.

You can look up the number of deaths caused by Chernobyl or Fukushima and compare it with the number of deaths attributed to coal mining accidents just in China or India in one year. Numbers are diminishing on both sides, due to improved safety practices. Still coal mining related deaths per year tend to be higher than lifetime deaths caused by nuclear plant accidents.
