All the laser recoil topics and graphics card power consumptions mentioned in all the threads combined with some RL talks about nutrition got me thinking, and all of a sudden I was curious enough to calculate something.
The average human needs about 2000 kilocalories' worth of food energy in order to "function".
2000 kcal = 8368000 joules
8368000 joules / 86,400 seconds (in a day) = 96.8518519 watts
A human needs about as much energy to live as it takes an old style lightbulb to function ?
That's NUTS !
:sigh:
If only we could run on electricity instead of food...

human body is not 100% efficient.
Also, we actually require around 2000 calories (not kilocalories) a day to maintain healthy diet....

Just replace my stomach with a Carbon Nanotube Battery the size of a Car Battery, and I am good to go for the next hundred years. According to some guy at MIT, a Carbon Nanotube Battery the size of a hand can store as much power as a Nuclear Reactor can generate in a few hours. That is enough to power an entire city for years. If you run your house on one of those, you won't have to pay power bills for another 50 or so years (assuming it is fully charged when you get it).

If it would be 100% efficient, it would require even less actual energy. I believe my point was that 100 W is an incredibly low average.

That's a common misconception.
The humans need roughly 2000 "Cal" (or "food calorie", or "dietary calorie" if you prefer). 1 Cal = 1000 calories. So, basically, kilocalorie.
Either way, humans need roughly 8 MJ of energy per day.

Well you'd still need proteins and minerals and such to regrow hair, nails, skin and various other deteriorating bits of the human body.
Also thanks for reminding me how terrible the Matrix "Machines need humans as batteries" plot was.

Ooh, if that is the correct interpretation of your calculations, then your calculations must be wrong. The human body contains a lot of water, I have at least one cubic meter of water in me, and that water is maintained at 7 degrees higher then current ambient at we speak.

One cubic meter is 1000 liters of water. So.. you must be fat :)

Yup, one cubic meter of water is quite literally one ton (1000 kilos) of water.
Also, you're not exactly heating those unknown numbers of kilos of squishy watery meats, you're maintaining their temperature - waste heat from work done only needs to compensate for radiative heat losses , which depend on outside temperature and level of insulation between the human body and the environment.
In fact, that's why we even sweat - whenever we make some effort, the extra waste heat can't be efficiently radiated, so we cover ourselves with water which evaporates, and the phase transition of water from liquid to gas "absorbs" a lot of heat in order to occur.
Radiated heat depends on surface area, while caloric capacity depends on volume/mass. That's why small hot-blooded animals need to eat so much food (compared to their body weight) while larger ones eat far less (again, speaking as a percentage, not absolute number).
Those 2000 kcal are the average use per day for the average human doing average stuff while dressed appropriately in a comfortable environment.
If you're looking at people that do a lot of physical work/exercise, it's obvious they need far more than that. Some athletes have diets that border on 10000 kcal per day just to maintain weight, but then again, you're looking at a full-time exercise regimen for them.
Same goes for people that are put in a colder environment without adequate clothing, or a much colder environment regardless of insulating clothing. You can easily burn up 500-1000 more calories during the winter than during the summer just by not staying all day long in heated indoor environments.

The fact that we need it, makes think it should be included in the equation. Even though you're saying it's not a direct energy supply, it definitely facilitates it.

This thread lacks several Internetz Doktors, like a Nutritionist, an Endocrinologist and a rounded up plain Surgeon to adequate proper body measures so I can begin taking it seriously.
Interesting nonetheless.
Also on the Matrix plot, I believe the Humans as batteries was more a Punishment than an efficient answer on the part of the Machines regarding energy, that or as some strange friends pointed out, they derived nourishment from us on a "spiritual" scale.  <explaining Neo's powers on "reality">

Nah, the Matrix was last-minute executive meddling.
The original plot was that they're using the human brains as organic computers to massively supplement their own processing power.
But since the average movie goer was deemed too stupid to understand what that means, they switched it to "humans as batteries".
Imagine how the scene would be different if Morpheus would hold a CPU chip in his hand instead of a battery.

Okay, "Xenuria", i highly doubt your a savant, your ramblings are just that, ramblings. For all your claims, i can personally, just as easily, claim to have studied, and memorized, an entire college course, plus supplemental learning, in the fields of astronomy, AI Theory, and physics, by grade 7. Now, no matter how much i insist this is true, you can easily say it is false.
TL;DR I'm still looking for prove you are a "genius", instead of yet another idiot too stupid to recognize there own ignorance like 90% of the world.
ON TOPIC: Doesn't matter what you are, the average human body's power needs are relatively equal, the only real factors ahve to do with each eprsons uniquie chemical amkeup which deals with their insulation and metabolism, which can drastically effect the needed calorie intake, and power needed to fuel it all.

okk.........
Well let me put it this way... People on the autistic spectrum tend to have overactive metabolisms and heat issues.
People with autism "Run hot" meaning for reasons not fully understood they generate a great deal more body heat then that of normal people. They also require more caloric intake due to a very high metabolism. Try not to focus on what I have claimed to be true and instead focus on what you can actually verify as fact. Namely what I just articulated to you about heat issues.
I did some reading in the Ozonof book about autism and apparently people with autism have abnormal magnetic fields around their brain. They have on average larger brains and have denser neuronal connection in the pre-frontal cortex. As well as more sophisticated mini collums.
So... Based on the fact that autistic people cause more heat output and have stronger electrical activity in the brain more often what do you think this implies about their energy consumption?

Try and look past what you dislike about me and focus on the actual data and the question itself.
"The neurophysiologic consequences of abnormal mini column size and function are purely speculative. One could hypothesize that the increased number of columns expands the receptor capabilities of the neocortex, which might explain the heightened sensory awareness and aroused state of some children with autism." (Buxhoeveden and Casanova, 2002)
"Excessive brain size is more common in children with autism than in those with typical developmental orother cuerodevelopmental disorders. ( Davidovitch et al. 1996; Fidler et al. 2000)
Magnetoencephalography Findings indicate that children with autism have stronger magnetic fields around the brain then that of typically developing children. (Ozonoff Page 118-119)
"Electroencephalography abnormalities in children with autism have been well chronicled." (Ozonoff page 117)
Tl:Dr
People with autism have larger brains, more electrical activity in their brains, stronger magnetic fields around their brains, much denser neuronal activity then normal people.
So I ask you do you think that people with autism, like myself require more energy or less energy?

Well, if you "run hotter" it's obvious you'll use up more energy. There's absolutely no question about that.
How much more... well, that's another story. I'm thinking, probably 10% extra, 20% maybe tops. Total guesstimate though.

Do you know of any scientific way of finding out exactly how much?

Count calories being consumed, keep measuring weight.
1 kg of body fat is on average the equivalent of very roughly 7700 Cal (~32 MJ). Or if you prefer, roughly 3500 Cal/pound.
Calculations should work regardless of whether you're gaining, losing or maintaining weight, as long as you keep a precise caloric intake count AND you maintain the same fitness level (same non-fat mass). No idea of caloric value of human muscles, so it's important to not vary in muscle mass at all. It's actually best if you maintain your total weight too.
Ideally, you will measure your weight in such a way as to minimize variations of body water content and "waste" ballast - try to remain well hydrated overnight (drink sufficient water when you go to bed, try to avoid too much variation in salt content that would affect water retention) and measure your weight after you go to the bathroom in the morning right after waking up (after performing both of the usual bodily functions).
average daily calories burned = [ total calories eaten + 7700 * (Weight at start - Weight at end) ] / number of days passed
(use 3500 instead of 7700 if you use pounds instead of kilograms)

I was doing some research and came up for a theory as to why exactly people on the spectrum "run hot" as we discussed earlier.
I was re-reading my various textbooks and comparing with current research findings on EBSCOhost.
I think that the extra use of electricity could be several magnitudes more then an NT (neuro Typical). The hyper active and sometimes unexplained electrical activity in the brain of an autistic person when listening to music or during a state of hightened agitation or arousal could explain the large heat outpout.
If you imagine the brain as a CPU in a computer system it makes alot of sense. When a CPU is overclocked it generates alot more heat then when it is running normally or even under clocked. So in that way the brain of an autistic being comparable to a CPU is constantly having surges of electrical activity that sometimes has no discernible purpose or reason for happening.
based off of this I think the amount of electrical energy a normal human uses is also very closely tied to their brain and the electrical activity in it. The majority of electrical activity in the body occurs in the brain. So I would argue that the brain is the determining factor in how much energy a human uses.

2000kcal is one of many things that he needs to function.
100g sugar has 377 kcal (http://en.wikipedia.org/wiki/Sugar).
Even if we ignore drinking and breathing ... how long will you survive eating daily ~530g sugar (=2000kcal) and nothing else ?
