3rd working machine you gandmother could make _2nd Law crushed

What a joke! Quinn states in his image above that a "periscope" extended up from a submarine displaces the water around it, but doesn't "lift" any water. How silly can you get? Anyone who has ever taken a bath can tell you what's wrong with that claim. But of course that leaves Archer Quinn out, doesn't it. If your ocean is big enough you can just ignore the fact that the periscope is lifting water, can't you? If you are Archer Quinn, you can.

MarkE, your diagram doesn't include the magic "rams" that can force water out of a submerged chamber into another chamber full of water without doing any work against the pressure, nor does it include the magic doors which let solid objects through without letting any water pass, nor does it include the "disappearing water" that goes through the little hole to equalize pressure and then magically vanishes, only to reappear at the top of the tall water column, also without requiring work. And your floater displaces water! While Quinn's obviously does not, it simply floats up through the water without affecting it at all. When your floater is removed from the top of the tall chamber, your water level is now one floater's height lower, because you have not waved your magic wand, like Archer Quinn did in that silly video!

Magic is always an extra option.  Mr. Quinn is free to try and argue how his scheme can buoy a float upward without replacing the the float's volume with the buoying fluid.  It could be fun to see him try and do that.

Of course the water in the ocean is lifted when a submerged sub. extends it's telescope.
It is equal to volume of the telescope extension, spread over the entire surface of the container
holding the fluid and the sub..  Does this raise the pressure on the hull of the sub ?
YES,  but it's utterly insignificant when the container is as broad as an ocean ! The amount of rise is
so small that it is  practically immeasurable at this scale of proportion.  The wider the container the
less the effect of the the rise.

I read the document and the bad news still applies.

In this case can you please elaborate and explain why the machine is not going to work.

Addendum

The floater does not need to be hollow.
