The Sun outputs 3.9 x 10^26W, but it weighs ~10^30kg, so that would mean 10^-4W/kg.
Human beings are closer to 1W/kg at rest.

US Primary energy consumption = 30 Trillion Kwh/ year [1]
30 Trillion Kwh/ year / 8760 hrs = 3.3×10^12 W (watts)
3.3×10^12 W (watts)/ 330million = 10 kW/ person
10 kW/ person / 80kg = 125 W/kg
We can make sustained nuclear reactions in much less space using engineered pressure instead of gravity, so that skews the energy density ratio.
IIRC fusion reactors on earth use magnetic confinement to raise the temperature much higher than the sun's interior for a much higher rate of fusion reactions. I'm sure someone will be along to correct me if I got that wrong. ;0)
What more do you want to know.
Joking aside, this comparison is really beautiful.
Allow me to become a little philosophical but since human beings which are product of nature made plutonium, isn't the making of plutonium natural too?
I mean everything that is happening in this universe is natural!
I know the general usage of the words "artificial" for human-made and "natural" for everything else. But when we are talking at the grand scale of life and universe I think a human-made plutonium is as natural as bee-made honey.
My wife was recently asked to make a meal for someone who didn't eat "processed" foods. What level of manipulation needs to happen before a food is "processed"? Can beans or rice be dried and put in a bag? Can chicken broth be used if it's homemade, but the chicken came from a commercial farm? Or is extracting broth from a chicken processing it?
I've increasingly noticed many sub-cultures adopting odd definitions and interpretations of commonly used language with the expectation that everyone who interacts with their group understand their dialects. It's not really jargon or vernacular since the words are common to the language, just used to mean something different than the general population would understand. Similarly, artificial is now assumed to mean bad and natural good, when neither ascribe value by definition or in practice.
But your idea that people are failing to use Standard English and creating language subcultures around peculiar meanings of artificial/processed/chemical vs natural/homemade/organic is itself based on a very artificial distribution of language.
To me, the actions of stars fusing heavy atoms and then those atoms ending up in lumps of material somewhere sounds like a pretty complex system doing its thing.
