the team led by Steven E. Jones <https://en.wikipedia.org/wiki/Steven_E._Jones> achieved 150 d-t fusions per muon (average) at theLos Alamos Meson Physics Facility <https://en.wikipedia.org/wiki/Los_Alamos_Meson_Physics_Facility>.[9] <https://en.wikipedia.org/wiki/Muon-catalyzed_fusion#cite_note-13> Unfortunately, 200 (or 250 or even 333) muon-catalyzed d-t fusions per muon is still not enough to reach break-even. Even with break-even, the conversion efficiency from *thermal* energy to *electrical* energy is only about 40% or so, further limiting viability. The best recent estimates of the *electrical*"energy cost" per muon[note 5] <https://en.wikipedia.org/wiki/Muon-catalyzed_fusion#cite_note-14> is about 6 GeV with accelerators that are (coincidentally) about 40% efficient at transforming *electrical* energy from the power grid into acceleration of the deuterons. In the Rydberg matter measurement of muon production, just turn the lights on and you will get as many muons as you need.
