I created a crude drawing of a potential energy generating machine. In the least it would create a good mathematical exercise for students and at best open new ideas for energy producing machines

Principles to run the machine

[1] an enclosed container (X) of air submerged in water has a lifting force (Y) equal to the volume of the water displaced minus the weight of the container;

[2] connecting multiple containers one on top of the other creates a combined lifting force of (Y)+ (Y)+ (Y)+ (Y)+ (Y)+ (Y)+ (Y)+ (Y)+ (Y)+ (Y)
Which is a greater lifting force than (Y);

[3] the energy needed to fill one container is equal to the energy needed to sustain the combined lifting force of the 10 (ten) containers referenced above;

Formula used (ATM/V1) X V1 = bubble size

Output of this machine is 118,428 pounds of lifting force moving at 33 feet per second
