I am thinking why companies making so huge reactors, everything should be simple just for test to get energy

  It's a been a long time, but in a talk at Google, I think Bussard said that power output scales with the 5th power of the radius of the device. There's really no point making a small one.

    Bussard's last reactor concept, polywell, didn't work.

      Oh right, I had WB-7 confused with Wendelstein 7.
