    This is technically incorrect, because calories in food are measured using a bomb calorimeter or similar techniques. In this device a small sample is burned and the heat is measured, which indicates the number of calories it has.

    Uranium is fireproof. It has 0 calories.

    Even enriched Uranium with a lot of unstable isotopes would not give up noticeable energy/heat in regular sample sizes for this process.

      Just because the human body cannot extract the energy doesn’t mean the energy isn’t there.

      Edit: I love the pedants trying to force logic into an absurd post.

        Obviusly.

        But if we’re gonna do the math that way, every atom in the universe has an insane amount of energy.

        It’s just to get at it, you need to either split or fuse the atoms. Doing this just happens to be easy with uranium, it’s not that special in terms of energy density.

        And a bomb calorimeter isn’t precises either, but it gets close because burning the food is what our bodies do, too.

            Not your belly, but in your cells, yes.

            The reason you need oxygen, is that your cells use it to “burn” stuff a few atoms at a time, for energy.

            It’s the same reaction as fire. Oxidation. Though inside our bodies it happens in an extremely controlled manner.

            Although cellular respiration is technically a combustion reaction, it is an unusual one because of the slow, controlled release of energy from the series of reactions.

      You are confusing facts with measurements of facts. Uranium has a lot of chemical energy, just like food. Yes it’s different and not edible, but this is a flaw in the human body, don’t blame uranium for it

        Uranium has nuclear energy.

        But if we are gonna count that when discussing food, then every atom has a shitton of energy.

        Uranium just happens to be easy to split, hence we can actually use the nuclear energy.

        But if you could split the atoms of bread, that’s gona release unimagineable amounts of energy, too.
