It took almost two years but this article from Leif Holmlid was finally published
I followed since it was a preprint, and it underwent the process twice before getting accepted.
Muon-catalyzed fusion and annihilation energy generation will supersede non-sustainable T + D nuclear fusion
Abstract
Background
Large-scale fusion reactors using hydrogen isotopes as fuel are under development at several places in the world. These types of fusion reactors use tritium as fuel for the T + D reaction. However, tritium is not a sustainable fuel, since it likely will require fission reactors for its production, and since it is a dangerous material due to its radioactivity with main risks of release to the environment during tritium production, transport and refuelling operations. Thus, widespread use of fusion relying on tritium fuel should be avoided. At least two better methods for producing the nuclear energy needed in the world indeed already exist, using deuterium or ordinary hydrogen as fuel, and more methods need to be developed. It should be noted that the first experiments with sustained laser-driven fusion above break-even using deuterium as fuel were published already in 2015. Similar results for T + D fusion do not exist even after 60 years of development, which gives no confidence in this approach.
article is open access, as all Holmlid’s articles.
