The term cold refers to the energies of the particles and as such the quoted experiment cannot be classified as cold fusion at all. The acceleration of particles with an electric field to generate fusion is commonly used, for instance in triggers for nuclear weapons.
Creating fusion of a bulk amount of material is nearly impossible using this method, especially if the goal is to liberate more energy from the nuclei than is consumed by the system.
Well... How about millions of tiny meteorites impacting the surface...
