What is failing, what we would change, and the conclusion we are willing to defend.
Fusion energy belongs in the platform, but not as a magic sentence that solves climate, data centers, or energy abundance on a campaign timeline. The current facts are better than the old skepticism allowed and less mature than the hype implies. Lawrence Livermore's National Ignition Facility has repeatedly achieved ignition since December 2022, with an April 2025 shot producing 8.6 megajoules from 2.08 megajoules delivered to the target. That is a scientific milestone. It is not a commercial power plant.
The Department of Energy's 2025 Fusion Science and Technology Roadmap is the right kind of document because it names the hard parts: fusion materials, plasma-facing components, blanket and tritium fuel-cycle systems, supply chains, workforce, public-private partnerships, and commercialization milestones. The Nuclear Regulatory Commission is also building a proportional framework that treats near-term fusion machines under a byproduct materials approach tailored to fusion's risk profile. That is the right posture: move faster than fission regulation where the hazards justify it, but do not pretend fusion has no safety, waste, tritium, neutron-activation, or nonproliferation questions.
Fund fusion as a strategic public-private research and demonstration program with honest timelines. Fusion should complement today's clean-energy deployment and climate policy, not delay it.
Prioritize the bottlenecks DOE identifies: fusion-relevant materials testing, tritium breeding and accountancy, plasma-facing components, heat exhaust, simulation, component lifetime, and supply chains.
Use milestone-based public-private partnerships. Public money should buy learning, shared test infrastructure, open technical data where possible, and measurable risk reduction with firm limits on rescue funding for any single company's schedule.
Support NRC's proportional fusion regulatory framework while requiring worker, public, waste, tritium, environmental, and security protections appropriate to each design.
Preserve international science collaboration, including ITER lessons, while building domestic supply chains and workforce capacity for magnets, lasers, materials, tritium systems, controls, power conversion, and nuclear-grade construction.
Back fusion as a strategic energy bet, but fund materials, tritium, regulation, and supply chains before promising cheap power.
Turn frustration into useful pressure.
If this position misses evidence or a lived consequence, challenge it. If it holds up, help test it locally and connect it to the issues around it.
