Efficiency
To understand motor efficiency, it is important to understand the distinction between theoretical and practical efficiency. There is a subtle difference here, whose implications are significant for achieving industrial productivity on a small scale. The point is: what matters is the efficiency of using a force input (for conversion from mechanical to electical energy). It is important to understand what matters and what does not matter - from the viewpoint of achieving effective industrial productivity for a Regenerative civilization.
What matters is the efficiency of conversion from a mechanical input to an electrical output. Period. This is based on a given permanent magnet spinning in front of wires, in which voltages are created. should not be confused with how much energy it is theoretically possible to extract if effective magnetic forces are optimized. This is because unoptimized magnetic forces, such as magnets not being sufficiently close to the wires - do not matter - because only the effective magnetic force is used.
