Determining the caloric content of Jesus

Is this to measure calories? We did something similar in elementary school, our teacher would light a piece of snack on hanging above an aluminium dish, and we would count for how long it burned. Then we looked at the packaging and the snacks with more calories burned the longest.

If I recall my undergrad thermodynamics class correctly, you can calculate the calories in food by burning, but in an experiment like this too much of the heat would escape to the surroundings to be usefully measured. Usually they use something like a bomb calorimeter to make sure all the heat is captured and measured.

Related: a guy in Poland posted online about buying supermarket donuts to use as fuel in a wood-burning stove. The donuts turned out an order of magnitude cheaper than firewood.

Yeah I think i remember seeing that. The donuts were like 90% for some holiday

Poland is still fairly religious and I've heard accounts of the amount some people eat on Fat Thursday on the leadup to Easter. Pretty sure that a specific type of donut is quite popular for it. So yeah, probably related

I wish donuts were that cheap near me. The dollars to donuts phrase has been backward for like at least 10 years in my area.

That suggests you could mix flour and vegetable oil and maybe dry it into bricks which might be cheaper than donuts usual are. I wonder how dirty that burns...

Maybe the frying is the special sauce in making them more flammable? Fry donuts with a donut-fueled stove to get more donuts for fuel.

Could be. A little char can make things easier to light. But I've never tried lighting a greasy dough block, so I don't know whether it needs help or not.

Yeah you need a more eye-catching title, like
"I accidentally made a calorimeter?? Gone wrong - GONE SEXUAL"
Now that's a paper any journal would be itching to publish

Are nutritional/digested calories actual equal to their combustion energy?

The main substance that burns but doesn't necessarily get metabolized is dietary fiber, which is a category of some different polysaccharides that burn but don't get (fully) digested.

So high fiber foods would tend to give incorrect results in bomb calorimetry.
