    That’s a thousand days’ worth of kcals.

    On the other hand, that’s enough uranium for the rest of one’s life.

    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.

    And also, bananas are radioactive. If you ate 40.000 bananas in 10 minutes you would die of radioactive poisoning.

    If you are measuring calories that way, then you have to consider that anything you eat contains e=mc2 energy.

      That’s my excuse for getting fat. Even the air I breathes contains millions of calories

    I wonder what the best conversion rate from uranium kcals to human consumable cals would be.

    Like is nuclear power to LEDs to plants the best route? Maybe radiation to fungus to some kind of slurry?

    The second level of stupid here is that 20 million kcal would last ~ 22 to 27 years (at 2000 to 2500 kcal a day), so not very optimistic about your longevity.
