efficiency of everything!

Hi followers,

today im going to write something totally different, so be pepared to read some crazy stuff ^^

Okay, yesterday i had a conversation with a friend of mine (yeah, i have friends.... weird). It was about the efficiency of different motor types because he is a auto mechanic.
Then whe have seen a piece of bun on the floor and i asked "ever wondered what the efficiency of a bun is?"
After that question we had a huge discussion what you have to research to find that out.
I couldnt resist so i have done some research:
effeciency = energy you can use from it / energy you put into something
Example:
A 60W light bulb has a efficiency of 5%. You put 60W of power in it and only 5% are formed into light. the rest is warmth.
I thought buns would be better but read this:

So a normal bun has around 1053 kJoule of energy for your body.
not much because a normal adult man needs 7100 kJ each day. That doesnt mean you should just eat 7 buns each day. But theoretically it would be enough.
Check.

Lets say we already have all incredience at home and wont calculate what energy there would be needed to make the incrediences. That would be to much.
Your body needs for 10min of making the pastry around 55kjoule.
While you just watch 20min of backing the buns your body needs around 58,8kjoule.
A normal oven uses 1500 - 2000 Watt each hour. We bake our bun for 20min so lets say we need 300W just for the oven.
Remember:
Until now, we just have the energy we need for our oven and our own energy.
We dont have the energy which is needed to create all the incrediences. But after 15min of googling i gave up.
300Watt/20min are 1,8MJ (this was also googled) ^^

efficiency = energy output / energy put
efficiency of a bun =  energy we get from the bun / energy you put in to create it
efficiency of a bun =  1053 kJ / (55KJ + 58,8KJ + 1,8MJ)
efficiency of a bun =  1053 KJ / 1.9138 MJ
efficiency of a bun =  0,0055%


Talking about diesel motors would be bad with an efficiency of 30%....
Buns are killing this world!

Bye ;D


Edit:
Made a mistake but corrected it with a mistake. 7000 buns a day? Nonsense! just 7. But i calculated wrong in the first place with the numbers but in the end the result was the same. Fighting mistakes with mistakes. Yeah!

  2. I never actually gave a thought to this. Efficiency of everything. Go figure.

  5. Hahaha i actually enjoyed reading those facts. I would've never thought that by myself.

  10. I think it's more like 1053 kJ. Otherwise it'd have less than half a calorie

  11. damn, you were right. my mistake. (damn commas) >.<

  12. I think I learned this last year, but it is much more interesting when you said it :D

    AntwortenLöschen
  13. can´t really follow your thoughts of the efficiency of a bun.

    AntwortenLöschen
  14. They're probably a lot more efficent if you buy them ready made lol.

    AntwortenLöschen
  15. I think it's pretty cool that you just decided to talk about energy, reminds me of a physics class I used to have lol

  16. your site has a popunder. lol

    AntwortenLöschen
  17. interesting bit of info you throw out there. now using what youve learned can you apply it to anything?

  18. wow! you just blew my mind!

  19. i live in canada, and they are talking about banning neon tube lighting and regular lightbulbs, so that we can only use LED and high-efficiency "green" bulbs. 2 problems here; these forms of lighting dont give off enough light, also...is the government in bed with the manufacturers of green lighting products?

  20. Interesting... Seems like a good idea. i followed btw :)

  21. I'll be honest. The things you do in your spare time and the things I do in my spare time are totally different, hahaha. cool nonetheless

  22. Leds are the future! just have to invest more money on inestigation and optimize them.

  23. with all those kilojoules, those must be some hot buns!

  24. I read half of the post as 'bums'. Im not even dyslexic. WUT.

  25. Interesting read. I live in europe and the gasoline prizes are insane here.

  26. Haha Thats awesome. It takes a certain kind of special to figure the efficiency of a bun. Funny post man!

    AntwortenLöschen
  27. I'm glad I never considered buns as a good energy source :D

    AntwortenLöschen
  28. that's a awesome info! thanks!

    AntwortenLöschen
  29. Buns also create an energy field consisting of dark(chocolate) matter and the corresponding anti(oxidant)-matter that is created when baking.

  30. thats interesting, keep it up!
    I look forward to your upcoming posts! ;)

  33. "Efficiency of a bun"... haha clever.

  34. love love this blog... gonna make myself some tea and read through every post... keep my brain sharp this summer.

    plus it's stuff I'm not so good with... so it's good for me.
