ENERGY RECOVERY METHOD
It is possible to recover some of the energy that is expended to vertically move a module. Figure 14a shows a matrix of modules with a single module in the left-most column, shaded blue, and the 2nd from left column of modules are shaded green; these green modules will be used to raise the blue module, and to do this they will actuate the legs that connect to the blue module by pivoting it with an electric motor as they relay it to each other from one module to the one above it.
A module that is shaded green expends energy by actuating to raise the blue module; to indicate that a green module has done this it will be changed to red. Figure 14b shows the 2nd from left module in the bottom row lifting the blue module, which is also connecting to the 2nd from left module in the 2nd from bottom row for repeating the cycle.
As the blue module is raised by the 2nd column of modules each one of these modules expended some energy. All of these modules in the 2nd from left column that were green are now red to indicate that they expended energy after the blue module reached the top row of the matrix, as shown in Figure 14c. Here kinetic energy was converted to potential energy.
Some of the energy that was expended to raise the blue module can be recovered when it gets lowered back down to the bottom of the matrix. Figure 14d shows the blue module beginning its trip back down to the bottom, and it also indicates that the modules in the 2nd column that were red turn back to green as they pass the blue module down to the module below it, in the 2ndform left column, to indicate that energy was retrieved from the process of converting potential energy to kinetic energy with the use of gravity.
This energy can be recovered by using the same electric motor in the actuator that was used to raise the blue module by each of the modules in the 2nd from left column of modules in the matrix as a generator. This process could be used to recharge the same power sources that provided the energy to raise the blue module. This is beneficial because it both saves energy and reduces an undesired build up of heat waste.
