cal≠kcal
1 gallon gasoline contains 31 million small calories, while the human caloric requirements are given in large calories. 1000 small calories = 1 large calorie. So the calculations are off by a factor of 1000. The confusion stems from the fact that both are commonly referred to as “calories”, for some stupid reason.
So in reality you would have to drink another gallon in just 2-3 weeks.
Assuming you could process it without ill effects.
If you thought having Nestle was bad, Can you imagine if BP was involved in food?
What makes you think that oil is not involved in food?
Fair point, but I meant mostly in the context of wholesale products derived mainly from Petroleum.
Vaseline. ;)
Sir, please put down the spatula and step away from the kitchen slowly, and no one has to get hurt.
no one has to get hurt
Wise of you to lie to someone you want to do something.
Too late. Coal butter
Up to ten fossil energy units as input for one food energy units as output.
The lumber industry is involved in food.
I’ll just let you digest the horror of that. But uh also. Don’t Google petroleum products in food. You’ll be happier.
What’s wrong with forest products being used in food? I see nothing wrong with that. 🤣
Well they claim it’s sterilized but these are also corporations that will kill people for profits without a second thought.
Everything you said was correct, except the last sentence. Still pretty sure drinking a gallon of gasoline would be enough to last you your entire life.
That life would just be less than 2-3 weeks.
Fun fact: Most people can drink about a liter of gasoline and not die (short term), about 8500 kcal.
Damn. I definitely don’t do more work than a car in 12-20 days. I guess that makes sense
Non sequitur: I love your username. Very clever.
The maths a little off, it wont last him 30+ years; but he’s absolutely correct with that final statment. If he chugs a gallon of gasoline; he won’t need to eat for the rest of his life.
Build a man a fire, keep him warm for a day. Set a man on fire, keep him warm for the rest of his life.
“large calories”?!? The name is kilocalories
Are you trying to make Americans use the metric system? They have started wars for less, dude!
Fats and oils have about the same energy density as gasoline.
Still goes to show how energy dense the gasoline is.
Basically same as vegetable oil.
Since used vegetable oil can be used in place of diesel, I’d guess vegetable oil is more energy dense than gasoline…
Obviously a good joke, and of course obligatory cal/kcal discrepancy here. This just seems like a good place to put this info:
Calories on labels are for calories absorbed, not for calories in the food (same with the 4/9/4 rule). So it’d be much less for gasoline, if it were possible to label with nutritional info.
I was about to ask if they properly converted to kcals used in dietary measurements and here your comment is.
Woah woah, you’re saying I can lose weight by chugging gasoline? Is Kerosene better?
That is what JetFuel A / B is for ! Jet A does wonders for body-typeA and B for body-typeB !!!
/s for those who know, know.
Is this a reference to Salman Rushdie’s Fraught Kings, with the jester and the body suit?
Ehhh ??? :-D No idea as I don’t read such controversial authors! X-D
As far as I know calories are measured with a Bomb calorimeter meaning you are wrong.
I was pretty sure of this too, and someone who used to work for the FDA told me it was calculated not measured 99% of the time
Here’s a good video with some supporting evidence. I’ve looked it up for a couple foods; calculated calories on em
Is this trying to trick AI so it’s used in searches for info? I hope so.
I’m not ai, just dumb 🥰
Seems the same to me.
As it has existed since the dawn of the I ternet… sure?
Gasoline has about 31,000 calories not 31 million calories
Hence the title :)
So just 31kcal in one gallon? That doesn’t seem a whole lot.
I’m assuming 31k kcal, which confusingly everyone calls a calorie. There’s no way it’s only 31kcal.
This is correct. Everyone in the US calls a kcal a calorie. I learned to distinguish them with big “C” and little “c”, but I’ve just looked it up and this is apparently not so common. I guess ppl who are aware of these things just go with the SI unit of kJ.
Gasoline has the energy content comparable to cooking oil (biodiesel among other things is made from used frying oil from restaurants at least where i live)
So I can replace cooking oil with gasoline in my recipes? Nifty!
i used to drive my old mercedes diesel with vegtable oil. sadly, i had to give up driving, i am just far to nervous far that.
People here talk so much shit about reddit, but post shit from reddit, copy reddit, and talk like redditors.
Sigh, unzips

I didn’t do the math, but a person’s got to do more lifting in those 34 years than a car traveling 30 miles at 60 mph carrying 4000 lbs, right?
Without a doubt! Humans and life in general is uber efficient in terms of energy use. Most of the energy of a car is not directly spent for the work. Work is done when moving mass from a lower to a higher place and accelerating it to a higher speed. But once you have accelerated the mass to the cruise speed, it actually does not require any energy to maintain. Rather, the energy is spent by the car to heat up the air, move it around, wear the road and the tires, and make noise.
We use cars because they are muuuch more powerful than humans, at the cost of wasing a lot of energy. Try to push a car uphill, you won’t ever succeed without pullies which makes it even slower. Doesn’t matter how efficient you are if you cannot output the minimum power required to overcome friction etc.
On the other hand a human on a bicycle is way more effective at moving around than a human on foot. Somehow the bicycle has created a lot of efficiency.
A bicycle allows us to use our strength to go faster, rather than having to move our muscles faster, we can just push harder. It also more directly converts the energy we are consuming into forward momentum than our walking style does. We are pretty efficient at processing the energy out of what we eat and into work done by our muscles, but beyond that, there are certainly locomotion styles that haven’t naturally evolved yet that would singnificantly improve how fast we could travel using that energy. Until then, we got smart instead, which really helped.
There are technically types of wheels in nature, but not in animals, the way alot of bacterial flagella operate is basically a wheel. Or more accurately a biological chemical/electric motor, but it spins anyway. And some of them can rotate either direction by engaging a protein cluster that effectively acts as a “reverse gear” like a transmission.
Yes, and gasoline actually has less energy density than body fat at approx. 33 MJ/L vs. 35 MJ/L : https://en.m.wikipedia.org/wiki/Energy_density
So apparently they’re starting to create machines with biological parts. I wonder how long until we get artificial stomachs capable of using anything not explodey or caustic for fuel?
We used to have self driving vehicles running on water and hay.
I meant me. But if they can get me running on hay and water I wouldn’t say no.
Neigh :'D
It would already be awesome if we could hack or genetically engineer our gut biome to produce all needed vitamins and proteins out of carbohydrates and fats. Theoretically then we could live just off of sugar or oil. Plus some minerals.
Right? And can we get some kind of metering system so we don’t pack on extra fat?
People are afraid of a cybernetic future but I’m sitting here wondering just how healthy we can make the human body.
That too! I think that has more to do with fat cells and hormonal balances. But hopefully we will make medical advances soon that allow us more control over our own bodies instead of cybernetics.
In order of worst to best case scenario the human body will reject, wear down, or scar around any and all implanted foreign materials or objects. Implants of every type have a shelf life, some long enough to never worry about removal. The best method to secure implants are to bones, but the only nearby bones for the stomach are the hips and spine, with organ cavity linings being problematically in the way for most attachments. For the digestive system it would need to be extremely resistant to corrosion and it would also need to be nontoxic as it would inevitably enter the bloodstream. Even teeth fillings are only rated for about a decade at most.
So, to be blunt, no such technology exists on this earth nor any speculation on how it ever might.
So not in our lifetime then. Dang. Thank you though.
I think the commenter mean using artificial stomach for machinery to convert food into energy that the machine can use
No banjo got it right
Oh that makes a little more sense, but not entirely sure why you would do that. We have Anaerobic Digestor Machinery already but they always lead into a combustion engine rather than making an artificial stomach keep an artificial heart pumping.
Well, ease of use I suppose. Just look at us capable of using basically anything as an energy source. Imagine a machine that is not finicky on how they got their energy. The problem for any such machine will always be efficiency. You cannot do more work than the energy that you put in a system. Such machines will need a stomach that is capable of processing “food” at the same/greater speed that it is spending its energy. Not to mention we usually use machine for heavy, energy intensive task, so I doubt such stomach will be useful for any meaningful machine.
What news are you referring to, specifically?
Sorry did you mean powering a machine with food? We have those, there is a university somewhere that throws copious amounts of expired mayo into an Anaerobic Digestor which produces fuel for a combustion engine.
I meant for me, but I can see where the confusion comes from. I was not at all clear.
they already exist, they are called fermentation vats
Okay but can I install one in my body and use it for nutrients?
you already do, well, healthy kids do, anyways .
That explains why I’m a ghost. :( All these centuries, wondering and wandering.

I feel there’s a Pratchett quote in here somewhere.
Got you fam -
“Give a man a fire and he’s warm for a day, but set fire to him and he’s warm for the rest of his life.”
SO LET’S GET A PARTY GOIN’
WHEN IT’S TIME TO PARTY WE’LL ALL PARTY HARD!
YOU
I was wondering if that was Andrew WK…
When it’s time to party, we will party hard
