This paper is focused on three points: (1) overcoming obstacles to tokamak power plants may require a configuration modification as large as that of a stellarator. (2) The demonstrated reliability of the computational design of stellarators should change fusion strategy. (3) Deployment of carbon-free energy sources is mandated by the thirty-year doubling of carbon dioxide emissions. Carbon-free energy options must be developed and fully deployed within a few doubling times. Unit size and cost of electricity are only relevant in comparison to alternative worldwide energy solutions. Intermittency, site specificity, waste management, and nuclear proliferation make fusion attractive as the basis for a carbon-free energy system compared to the alternatives. Nonetheless, fusion is not an option for deployment until a power plant has successfully operated. A critical element in a minimal time and risk program is the use of computational design as opposed to just extrapolation. Only the stellarator has an empirical demonstration of the reliable computational design through large changes in configuration properties and scale. The computational design of stellarators should proceed while the inventions necessary for a more tokamak-like power plant are sought. The cost of computational design is extremely small, but adequate time is required for the development of ideas that maximize attractiveness and minimize risk. Rapid power-plant construction without many intermediate steps may seem risky, but the price is small compared to the cost of trillions of dollars for each year’s delay in addressing carbon-dioxide emissions.

本文重点关注三点：（1）克服托卡马克发电厂的障碍可能需要像仿星器一样大的配置修改。(2) 仿星器计算设计的已证明可靠性应该改变融合策略。(3) 二氧化碳排放量三十年翻番，要求部署无碳能源。必须在几倍的时间内开发和全面部署无碳能源选项。单位规模和电力成本仅与全球替代能源解决方案相比才相关。与替代品相比，间歇性、场地特异性、废物管理和核扩散使聚变作为无碳能源系统的基础具有吸引力。尽管如此，在发电厂成功运行之前，聚变不是部署的选项。最小时间和风险计划的一个关键要素是使用计算设计，而不仅仅是外推。只有仿星器才能通过配置属性和规模的巨大变化对可靠的计算设计进行经验证明。仿星器的计算设计应该继续进行，同时寻求更类似于托卡马克的发电厂所需的发明。计算设计的成本极低，但需要足够的时间来开发最大限度地提高吸引力和最小化风险的想法。没有许多中间步骤的快速发电厂建设似乎有风险，
