Not sure I understand how fused H-BO atoms will produce electricity directly that can be captured. Unless what they are saying is that the fusion produces electrons....but then the higher energy values don’t make sense.
So how is the ‘direct electricity’ being captured? Induced from a generated mag field?
The fusion event results in three fast helium nuclei (alpha particles) which carry an electrical charge. Running them backwards through an accelerating device against a bucking voltage results in a DC current at high voltage.
