They are over halfway through this funded (about $8 million) project. This part is just one step towards commercial fusion and if successful could justify a $200 million follow up to develop a full commercial scale system.
As one commenter notes:
In earlier statements it was explained that WB-8 was only going to be produced if WB7/7.1 were successful — i.e. validated WB-6 results. I think we can assume that happened. WB-8 is to determine scaling. This means a lot of testing to provide a lot of conclusive data for peer review. The fact that the research is ongoing, means they’ve hit no serious snags – the contract would end if they did. This is a very very positive report, do not listen to the naysayers.
