  1. This is supposedly a D-H3 reactor but operating at only 100M degrees, where D-D fusion is orders of magnitude more productive. So how are they not going to get fried by neutrons again?

  2.  @elmarmoelzer2229  you are still going to get extreme neutron flux from D-D chain whether you want D-H3 or not. This is a big reason (other than He-3 being impossible to come by) that most proposed commercial reactors use the tritium chain. That and 1000x better reaction rate.

  3. Flow within the boundary layer is, by definition, laminar, not turbulent.

  4.  @charliem6590  well the science will out. I just can’t see this thing doing much when it takes a 90% haircut even at a billion kelvin.

  5.  @limcheating1  that's called a contract. The Democrats and Republicans don't sit on SpaceX's board of directors. In Chinese space companies, the CCP literally does.
