Energy production has always been an enormously capital intensive venture. R&D labs aren't known for their industrial optimization unless that's their research goal. They proved this from the perspective of the fuel pellet - now they have to increase energy yield (larger fuel?) , reduce total system power, etc. That said, they doubled energy yield in less than a year. The early exponential function on emerging technologies is always fun.
