I was a little disappointed that their presentation did not include any specifics on muon production. As muons are so heavy, their production must entail a lot of energy. I would have liked to have understood from whence the energy came; whether from an external power source, or some earlier fusion byproduct.
Also, the process generates neutrons, which are responsible for for the radioactivity associated with waste. How long-lived is the waste? (something that’s likely already known for the well-researched fusion antecedents)
Here’s hoping they break loose with a bit more detail soon.
