Brings up a good question.
Their small scale research may point to a future where it is more economical to produce many smaller fusion plants instead of the massive commercial electric plants built today.
Think of the reduced grid infrastructure needed if power plants that required only a 3,000 square foot building 2 stories tall could power a city block or a single NYC skyscraper.
Instead of building massive plants in place you could have an assembly line producing power modules that could be delivered on flatbed trucks.
