>>> An iPhone powered by body fat could last...9 days
This only shows how extremely efficient our body is. We can survive without food - with water though - for maybe 40-60 days depending how much fat you carry.
- gene-h 11y agoOr how energy dense fat is if you ignore the conversion efficiency. For this calculation they also assume the whole volume of the battery is filled with fat. Humans actually aren't that efficient in terms of conversion of chemical energy to mechanical work. Muscle is about 14-27% efficient at converting chemical energy to work, which is about as good as a combustion heat engine. Now in terms of motion planning, image recognition, and "cognition," humans tend to be more energy efficient than machines.
