Ken also claimed that the decay results would be "pure energy". My
initial reaction is that conservation of spin and charge would preclude
complete conversion; not all of the products would be photons.
Anyway, what we want is the best matter-to-momentum conversion, not the
best matter-to-energy conversion. Converting matter to photons does get
you the most momentum for a given amount of matter, but it's probably
not feasible to convert matter completely to photons.
