Dynomak Fusion Reactors

What does “cost competitive” mean? Well, relative to prior fusion projections, a Dynomak facility could be built for about a tenth the cost of competing fusion reactor designs and produce up to five times as much power. This lets it catch up to the price-per-watt of coal, though only at the gigawatt scale; a 1GW Dynomak reactor might cost $2.7 billion, to a modern average of $2.8 billion for comparable coal plants. It’s all theoretical of course — this team has presented a major improvement to reactor design, but it will be up to larger, better funded research teams to actually make use of it.
