Welcome to /c/tumblr, a place for all your tumblr screenshots and news.

Our Rules:

  1. Keep it civil. We're all people here. Be respectful to one another.

  2. No sexism, racism, homophobia, transphobia or any other flavor of bigotry. I should not need to explain this one.

  3. Must be tumblr related. This one is kind of a given.

  4. Try not to repost anything posted within the past month. Beyond that, go for it. Not everyone is on every site all the time.

  5. No unnecessary negativity. Just because you don't like a thing doesn't mean that you need to spend the entire comment section complaining about said thing. Just downvote and move on.

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?

[–] Crackhappy@lemmy.world 17 points 1 week ago (3 children)

What makes you think that oil is not involved in food?

[–] franklin@lemmy.world 6 points 1 week ago (1 children)

Fair point, but I meant mostly in the context of wholesale products derived mainly from Petroleum.

Sir, please put down the spatula and step away from the kitchen slowly, and no one has to get hurt.

[–] flicker@lemmy.world 4 points 1 week ago

no one has to get hurt

Wise of you to lie to someone you want to do something.

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.

[–] WoodScientist@lemmy.world 4 points 1 week ago (1 children)

What's wrong with forest products being used in food? I see nothing wrong with that. 🤣

[–] Maggoty@lemmy.world 2 points 1 week ago

Well they claim it's sterilized but these are also corporations that will kill people for profits without a second thought.

[–] jballs@sh.itjust.works 16 points 1 week ago (1 children)

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.

[–] muix@lemmy.sdf.org 10 points 1 week ago

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

[–] Crackhappy@lemmy.world 2 points 1 week ago

Non sequitur: I love your username. Very clever.

[–] Darkassassin07@lemmy.ca 14 points 1 week ago (1 children)

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

[–] Tja@programming.dev 17 points 1 week ago

Are you trying to make Americans use the metric system? They have started wars for less, dude!

[–] A_A@lemmy.world 2 points 1 week ago

you are right ... but sorry : that stupid way of calling it is really in use in America.

Fats and oils have about the same energy density as gasoline.

[–] InternetCitizen2@lemmy.world 3 points 1 week ago (1 children)

Still goes to show how energy dense the gasoline is.

[–] Tja@programming.dev 5 points 1 week ago (1 children)

Basically same as vegetable oil.

[–] Malfeasant@lemm.ee 5 points 1 week ago (1 children)

Since used vegetable oil can be used in place of diesel, I'd guess vegetable oil is more energy dense than gasoline...

[–] hemko@lemmy.dbzer0.com 2 points 1 week ago* (last edited 1 week ago)

So based on a random articles I found in internet, mass density of vegetable oil is around 900kg/m^3, and gasoline 800kg/m^3, and since we know that E (energy) equals to m (mass) times c^2 (speed of light squared), we can tell that veggie oil indeed is more energy dense than gasoline.
