I think he's having the time of his life. This is a science geek who has managed to turn his home into a Mad Scientist Laboratory where he can play. I've got enough of a science background to recognize his engineering and scientific competence. I believe all the stuff he does is reliable. My one complaint (if it _is_ a complaint) is that the topics of his videos are so random. One video will be about focussing microwave energy into a beam to use as a weapon. The next will be about distilling Rum, and the next will be about producing graphene to strengthen epoxy. I mean the guy is all over the map. But that's part of his charm.
