Have a look at this video.

He seems to use the weight going down to produce electricity and probably the last few inches of the distance uses
some kind of compressing with this weight some air going into a balloon fixed to the weight to press the air into the balloon
and thus using boyuancy lift to bring up the weight again.

I wonder if this is enough lift to bring up the weight again when he used already most of the distance to propell a generator ?

Tommey reed work on a similar project, I believe it can work, he must go open source...

I don't understand how he is compressing air as the weight is immersed in water to provide buoyancy.  His description is rather vague.

[fletcher]

It looks like a hollow plastic tube descends with the 'sphere' mass on a string - when the mass is fully descended air is pumped under pressure from a reservoir into a bladder inside the 'sphere' displacing the internal water & raising the vessel water height accordingly - the sphere volume now has less density than the water & has a net buoyancy force which causes it to rise.

N.B. on the way down the mass accelerating due to gravity [having a density greater than water] turns a gen or some such which makes electricity which turns a pump to compress air into a pressure vessel - the elastic bladder [like a balloon] then reduces volume again with the air exhausted I think - I don't think the sphere ever leaves the water.

The cycle repeats.

Over time I would expect his pre-charged pressure vessel to deplete its pressure - he would probably say that this was due to poor workmanship, tools, equipment, engineering, efficiency losses, & various leaks that once fixed would solve the 'losses' problem & the system will consistently show OU over time.

Add a load to the system that take energy away like supplying electricity elsewhere & he is banking on the system being able to recharge the pressure vessel & do external work and cover inefficiencies & losses.

Perhaps he hasn't read about the Work-Energy Equivalence Principle in physics OR he has got something - you be the judge.
