For all intents and purposes, when someone says cal they mean kcal. A single actual cal is so ridiculously small it might as well be irrelevant.

Even after energy losses, a person can push a few watt hours into a battery with a hand crank in 10-15 minutes, drastically exceeding the energy output of 2000 calories.
