Stellarators have become easier to design, but they're still a complete pain in the arse to build. Wendelstein 7-X was nine years behind schedule and significantly over-budget, mainly due to unforeseen problems in assembling the coils. The National Compact Stellerator Experiment was abandoned in 2008, again due to construction delays. For stellerators to become viable, we need some major advances in manufacturing technology. https://en.wikipedia.org/wiki/Wendelstein_7-X https://en.wikipedia.org/wiki/Wendelstein_7-X https://en.wikipedia.org/wiki/National_Compact_Stellarator_Experiment https://en.wikipedia.org/wiki/National_Compact_Stellarator_E...
