"Thanks, I wondered how you eventually turned it into shaft work, I didn't realize they could funnel the neutrons. Then you have a standard moderator-to-heat solution. You are saying the neutrons can be funneled, right? Or am I missing something?"

Not really. They need to use the "moderator" approach with neutrons because they CAN'T "be funneled". They have to be "slowed down" and lose energy by collisions with a light nucleus (like the protons in water).

But with the PB11 reaction, the products are two high energy alpha particles, which can most definitely be funneled and slowed either by electric or magnetic fields.

Thanks to both of you! I love these threads.
