Field notes

The page gives two material figures—0.11 kg of hydrogen and 15 MJ of heat per kilogram of aluminium—labelled established, while reporting no measured reactor. It says 72 Australian applications and two international families have been filed, with 25 claims described as new and inventive; none is granted. Fusion-related lithium sorting is presented as a horizon, not a product.
