I admit I haven't taken any conventional physics courses, but I had this idea for a machine which would make use of a large drum of water, and a necklace of buoys made out of spherical steel. Almost half the buoys would be pulling on the cable linked to a lower wheel through buoyancy, while the other half would be free-falling through air outside of the drum into the lower wheel. A wheel on the lip of the drum would feed the buoys one by one out into the air from where they bob on the surface of the water.
It seems to me that the only resistance met with for all that pull of buoyancy (and I have estimated upwards of 15,000 kg in a 30m drum) consists of
A. The resistance of the guide wheels
B. The resistance of the wheel axes
C. The resistance of the single buoy entering into the water from beneath and
D. The water resistance at greater speeds.

I apologize for my earlier, extremely inaccurate equations.
I estimated the column of water in a 30 meter drum would amount to 148-258 kg of pressure at the bottom of the drum (according to a water weight calculator at
Water Weight Conversions) which is exceeded even by the buoyancy of the single deepest buoy--1050 kg.
However, in reality the pressure may be equal to the weight of the column of water--about 23,000 kg. If the buoyancy could exceed that, as it might if it is proportional to depth, then the machine is one degree more viable.

The major difficulty seems to be preventing the drum from leaking, by making effectively watertight transitions between the air and the water.
Of course all of this is based on rough approximations, and the fact that I am unprepared to patent it may be evidence of its failure in producing free energy. Nevertheless, it seems hopeful to me, and I am waiting either for evidence that it is false, or some degree of validation.
For those that find it either intriguing or preposterously amusing, I recommend the diagrams and descriptions of the math I have utilized, which I have posted on my website at
Perpetual Motion Machine Using Rising and Free-Falling BuoysI'd be curious to know exactly what physics principle this violates, if there is any besides simple water pressure. I see no fault with the rotation of the buoys, provided that the right sort of guide blocks are provided.
I suppose its possible that I have failed to calculate the weight of the water above the "lower meniscus", that it is impossible for any number of buoys in a given shaft of water to equal the force necessary to enter the water from beneath. But I did my best to be conservative in my estimates, with the hope that they have validity. Maybe I'm just a delusional fool, and I know we don't always get credit for good intentions.
Nevertheless, it seems to me that the concept does not break the rules many other perpetual motion designs have done, because the imbalance can be sustained so far as I can determine. Maybe there is just a cruel law which prevents things from easily entering water from beneath. But I would think that could be solved by making the buoys aqua dynamic (the plan is to have the cable attached to each end of the buoy, running through, so that the wheels can catch them, and so that there is less bobbing when they reach the surface).
