I'm surprised to see so many poetvers just discovering photonicinduction now.. I'm pretty sure I found him through poetv years ago.
Initially I thought: This guy is crazy and he will soon blow himself up (and possibly some neighbours)
Then I realised he actually has his own company which perform *industrial* electrical engineering, on stuff like power grids, power stations, factories etc. These guys have to be extremely professional and educated about danger as in those situations the voltages and such involved are staggeringly huge and also in order to not disrupt production / electricity provision work in often done on them while they are live.
So, what he is doing here is just playing around to unwind, this is the equivalent of a train driver having a model train at home.
