- TL;DR Summary
- What is the expected or realistic percentage of neutrons that will be caught to extract energy from a fusion reaction?

Surely the real efficiency of Fusion power is the percentage of neutrons that can be caught to extract kinetic energy from. I am assuming it is the neutron that is carrying the nuclear energy that can be recovered from the fusion reaction.

Now I'm pretty sure neutrons cannot be focused, so the capture of these neutrons in a 'neutron capture blanket'(for want of a better term) will have to be absolutely complete, totally surround the fusion reactor and be thick enough so that no percentage of neutrons get away.

I can't say I have ever read any discussion about this loss of efficiency.
