Nextbigfuture has been constantly tracking nuclear fusion and advanced nuclear fission every week for the past 13 years.
The popular question is when will we have commercial nuclear fusion that has a significant impact on the energy production of the world?
MIT has spunout a tokomak fusion project into Commonwealth Fusion systems. They want to apply modular designs to high-temperature superconductors. They want to get to stronger magnets that will shrink the size and cost of the potential nuclear fusion reactor. Improved magnets would improve any nuclear fusion design that involves confinement of plasma. There is less science risk to this MIT approach but more technological risk. They are trying to accelerate the commercial use of high-temperature superconducting magnets and trying to contain their costs. Cost for superconducting magnets for past fusion projects have been $20 per watt but other applications have seen costs of $1.4 to $1.8 per watt.
