I seem to remember a few years back this guy made a lot of noise about a "free energy" (ahem) device he'd invented and claimed he was giving the plans to China and Russia as a way of getting back at the UK government for some slight or other, then promptly dropped off the face of the internet in protest(?) I guess he's back.

IIRC it worked by using a big gyroscope to stay stationary while the earth rotated, causing 1 rotation every 24 hours. So not technically free energy, just taking it from the earth

I was quite worried that he'd gone off the deep end when he published that video

Whatever came of his hydrogen/electrolysis project? He has talked before about how those big control panel boxes he made and the high voltage transformers were to contol some kind of high power electrolysis rig that would make a huge hot-air-balloon-like flame. Not sure if that was some kind of free energy effort or if he just wanted to make fire with electricity.

I remember him showing a cube with an outlet and a switch that could power a lightbulb. He eventually revealed that inside were just a bunch of lithium ion cells taken out of disposable vapes

That’s not a very charitable interpretation. He was distraught about not being able to get his wife into the UK and was lashing out. He removed the video, he knows it was silly. Hopefully the situation was sorted.
