If only man would copy Nature more effectively he would learn to achieve ‘more with less’. Man’s electrical devices are very inefficient and do not multiply their effect much above a factor of 1.
Imagine, building a road from Milan to Rome. Design protocols will usually dictate that the road will have a uniform width so that the movement along the road is same from either end. This design philosophy is carried over into electrical design whereby most solenoid coils are wound with wire of the same uniform loop diameter. While this configuration is capable of generating a polarised condition, the multiplication factor between each wire loop is one. Multiplying by one does not really multiply !
The movement in the vicinity of Rome would be very congested, and great effort is necessary to maintain a constant throughput along the 6 foot section of roadway. This increased effort is registered as increased heat, light and density.
The movement around the vicinity of Milan on the other hand will be much more sedate. The road dimensions ensure less effort is necessary to maintain that same constant throughput which is manifested as cold, dark and nebulous the opposite to the experience near Rome !
This is exactly the geometry Nature utilises to divide her pairs and which then define the anode/cathode conditions. In Nature’s desire to maintain a constant throughput, her effort must be multiplied at the anode and divided at the cathode. This need to multiply is entirely a function of the geometry she employs to divide her polarised conditions. She opts for conical man has shackled himself to cylindrical configurations.
