yes. There are some videos that do capture it irrefutably IMO. Unfortuneately John's never been that great with gettin clear video, and his major work was done in the 70s and 80s and video equipment that he had wasn't of great quality. But the many metal samples he has accumulated over the years show destructive and transformative effects that are impossible to reproduce with other means - Bob has been studying them under electron microscope if you look through the videos on the Martin Fleishman Memorial Project's youtube channel.

Of the videos of note: One shows John deform an iron bar - it crumples in on itself like it's somehow metlting from the inside, but it's cold. another shows a metal sampl start to wobble like it has become jelly - john refers to it as 'jelly metals' he saw it so many times. There is talk in place online that it's possible to cold-pour mteal into a mould using this method that John accidentally discovered - ie black ops manufacturers already have this capability.
In the best quality video of one of johns experiments, recorded by a documentary crew on a high quality VHS camera in early nineties I think, you can quite clearly see objects levitate and a metal pendulum briefly becomes invisible.

There has definitely been a effort to discredit John though. It started after there was military interest in his experiments and he had seemingly friendly lab visits from people from the pentagon.

its all shady af, but i always leaned in that direction. john claimed in few interviews ive seen to have problems replicating the results. 
u seem to know a lot about him

Everything I know I've just read or seen in interviews with him and others. John always had trouble repeating effects exactly or on demand. This was frustrating for visitors who couldn't spend days and days with him, for hours at a time, waiting to see if something would happen when he fiddled with his knobs (heh). Things generally happened after hours of nothing happening, after lots of tweaking on his part. Also he only ever used mains power triggering the breaker was probably an issue too. 

He's not a highly organized and methodical, professional scientist - he wouldn't record what exact settings he would use on every machine after a successful experiment. I think he actually worked by memory mostly. Like I said, he's a chaotic dude. 

Also the nature of the effects he was producing are chaotic in themselves - he might be trying to levitate an item in his target area (in the way he had done previously) and instead something elsewhere in the lab would levitate, or even on another floor, and he'd only know after hearing it crash to the floor again. Things like that. When his lab was in his apartment, his neighbours televisions were often affected. 

Personally I think part of it might be that atmospheric conditions play a part - which are inherently not controllable - humidity, pressure, etc. I think Tesla had a better grasp of this and had the means to build his lab in exactly the place he wanted. john has always had to make do.

yeah, it would be hard for a hobbyist to even have the gear and power output needed to play around with this stuff. on the old yt channel he offered all the data he had for anyone interested. was selling the metal samples on ebay 

the basic crystal battery stuff from him was easy enough to be replicated by hobbyist though. always wondered why nobody put a nice box on it with a led light and product it

The thing about the power input - the effects he produced should require more power to achieve than he was putting in. It's one of the major reasons why 'skeptics' refuse to accept the Hutchison Effect as real. He is releasing power from 'the vacuum' using second hand equipment running only on mains power supply. It's an incredible achievement.

i always figured he was aiming a lot of different types of currents in one place, (like you would collect sunlight through a lense to make it hot in one place), and the resulting field was unusual, unstable and dense enough to have weird results. heard that he was using some additional power generators too, but idk about any of that
