Perpetual Motion Machine Concept Utilizing Rising andFree-Falling Buoys, Second Iteration.EQUATIONSRising and Free-Falling Buoys Continuous Motion Concept.For the purposes of calculating the relative merit of various heights of the upper tank, sizes of buoys, and widths of the lower tank, I used the following equation:Over-unity if (w + b) > (r + f)where w = effective weight of buoys on the falling lineb = effective buoyancy of buoys in upper and lower tanksr = entry resistance for the single buoy entering the lower tankf = estimated frictional loss at any given time including wheel                    resistancew isn't the full weight of the falling buoys, but rather the proportion of their weight that is vertical. Thus where u is the upper angle, I had to use the equation(90 - u) / 90 = proportion verticalI could then multiply the proportion that is vertical by the weight of the falling buoys (requiring a calculation of the length of the falling line times the number of buoys per meter). Then I would have the effective gravity i.e. the pull force in kilograms exerted by the falling line.So we have w.The buoyancy within the upper tank is simply the buoyancy per buoy times the number of buoys in the upper tank, since they are rising vertically.I estimated the buoys in the lower tank exerted half their force, since they are rising at a 45 degree angle, assuming the wheels are well attached to the support structure.0.5 * number of buoys in lower tank * buoyancy per buoyAdding the upper and lower buoyancy, we get b.The entry resistance r is equal to the proportion of the water in cubic meters supported per square meter of the bottom, times the cross-sectional area of the buoy at its widest point, in square meters.The proportion of the water in cubic meters supported per square meter of the bottom is found by taking the water weight of the volume of the upper cylindrical tank, adding it to the weight of water contained by a cylinder with the average circumference of the lower tank, and dividing by the area in square meters of the bottom of the lower tank.Thus there is a strong reduction in entry resistance using a broad lower tank and elongated upper tank, since much of the upper water weight is distributed over the surface of the bottom of the lower drum.Factoring in the size of the buoy, smaller buoys require much less resistance, but are capable of much less buoyancy and gravity. Beyond a certain size the minimum entry resistance may be prohibitive. But less so than would be the case in a simple cylindrical tank along the lines of Frank Tatay's design of 1929.I have had difficulty estimating friction, in part because I believe that a minimum of constant force would render friction irrelevant for all purposes but determining percentage over unity.We know that when things fall, they keep falling until they meet the ground, and when things float they float until they reach the surface. It seems doubtful that either of those forces would be stopped by friction. Slowed yes, stopped no.Thus what remains is wheel resistance, something that is largely a matter of technology, and which I estimate is proportionally less significant the larger the scale of the device, much like a wider barrel of a gun generates much greater force. Only I don't intend to use explosives.Rising and Free-Falling Buoys Data       nathancoppedge.com NATHAN COPPEDGE--Perpetual Motion Concepts
