Yeah, the actual reactor is 2.5-3 meters across:

The good news seems to me to be that as soon as someone decides to put money into either focus fusion, or the bussard process, then a lot of other people are going to start thinking that perhaps they should try the alternative – so IMHO this actually increases the chance of raising funding for focus fusion – another opportunity to break the funding logjam.
