They should increase selectivity of process on orders of magnitude.
But in any case the rest mass of pions is 140MeV.
So, it is impossible for their creation to spend less energy than 140MeV.
And even in case of 100% selectivity but if taking into consideration efficiency of accelerators 30-35%, energy have to be spent per each pion from plug-to-pion would not be less than 400-467MeV.
But who believes that 100% selective pion production process is possible?

Then.
If I understand correctly, they declare that quantity of muons 1-2% from occurred fusion events.
So, one muon makes 50-100 fusion events.
If we take lower 400MeV per muon, required energy for their creation cpecified per each fusion event will be equal to 4-8MeV.
They talk about D-D reaction.
And how much energy can be gained from each fusion event?
More than 4MeV?
Effeciency of energy conversion? If 40%, so, 1.6MeV gained from each event.

output 1.6MeV vs. 4-8MeV input
And that if 100% selective process. Which is impossible by definition!
