He seems to be following the Instructable rather closely. Or the LLM was following the Instructable.
See fusor.net.[1] It's unlikely this rig is doing any fusion. It's just a plasma created by high voltage, like a neon lamp. He's not putting in deuterium gas. He's not detecting neutrons.
Most of the people who try to do this get the blue glow, but not neutrons.
The main hazard is then the high voltage.
These things are not energy producers. It takes about a billion times as much energy input as comes out in neutrons. They can be useful neutron sources for imaging and research.
