"A battery will discharge if the outgoing current is less than the incoming current"
"Yeah, but the current controller won't perfectly convert the incoming electricity to a state usable by the battery"
Okay, so? What is the actual argument here?
- TheCoelacanth 6y agoThere are far more variables that affect how much energy a human body can get out of a piece of food than affect how much energy you will get out of a battery. If you define "calories in" as "how much the person actually metabolized from the food they ate", then "calories in - calories out" will obviously determine their weight, but you can't actually measure calories in using that definition, so it's a useless definition. For dietary purposes, the definition people are using is the number on the packet of food they ate, which there is obviously no law of thermodynamics requiring that it perfectly match their change in weight.
