A FF engine generates electricity through particle beam & x-ray recovery rather than heat extraction. This is why the construction cost is so dramatically lower.

A decelerator, as opposed to a particle accelerator, is put in the line of the tight pulsed beam of charged alpha particles (He nuclei) that is the result of the pB11 fusion. More electricity is generated by passing the x-rays through a shell of thin metallic foils, with the electrons captured on wires held at negative voltages.
