Please show me how your theory works on this example.
A 12 volt battery is connected to a motor with 2 wires, one from the positive battery terminal to a motor terminal and the other wire from battery negative to the other motor terminal. A simple circuit. Two components, a source (battery) and a load (motor). The motor has a fan attached to its shaft which presents a mechanical load to the motor. Say it spins at 2000 RPM and draws 10 amperes from the battery.
Analysis: Battery voltage = 12V, battery current = 10A. Battery power = 120W. If the circuit runs for 20 seconds, then 2400J of energy are removed from the battery.

Turion don't let math control his decisions on what the project build for experimentation is going to be. Dave's experiments are just that, try it. The rest of the people never try. So Dave sees a need and out of necessity begins to explore. When his Dad was still around he helped solve some problems associated with small or weak energy systems like solar / battery banks.
