    generate the waste heat of 23 atom bombs a day.

    Americans will do anything but use the metric system.

        Let’s assume Costco size hot dogs (1/4 lb, or 0.11 kg), with an internal temp increase from fridge temperatures (37 F, or 276 K) to 165 F (347 K). Let’s also assume the heat capacity of the hot dog is about 3000 J/kg*K. To heat up a single hot dog takes this much energy:

        q=mc*deltaT => q=(0.11 kg)*(3000 J/kg*K)*(347K-276K)=23,430 J of energy.

        The heat capacity here is 9GW. That is 9 gigajoules of energy per second, or 9 billion joules every second. Divide this by the number of joules to cook each hot dog gets us the number of hot dogs that could be cooked every second:

        9,000,000,000/23,430=384,123 hot dogs/second

        With this hot dogs per second figure, we can find how long this energy source would take to feed the entire US population a Costco hot dog.

        342,000,000 people/384,123 hot dogs per sec=890 seconds

        Converting this to minutes:

        890/60=14.8 minutes

        So, this source of energy could feed the entire population of the US a Costco hot dog in less than 15 minutes if properly harnessed.

          The math you just did terrifies me and I have no way of verifying it, so I’ll just say good job and leave it at that.

          I think it’s also important to have a hotdogs per day figure, and the math from here is super simple, so I can do it.

          384,1236060*24 = 33,188,227,200 hot dogs per day.

      At least in this case it gets across the truly stupid amount of energy being wasted. As a general rule I think that if you can boil one of the great lakes with your daily thermal output you probably shouldn’t be doing it.

      9GW is first. That’s metric. The other number is to give an estimate that is more relatable.

        but first is peak power, not waste energy, we’re still missing the SI estimated number of Wh wasted per day

          True, yeah. It should be Wh, not just Watts. I think most data centers are designed to run 24/7 though, so the Wh might be close to the same as peak.

          If they can tell us how many “atom bombs” per day it takes to power it, at least we could figure it out!

    They should really try boiling some water with that waste heat, maybe make it spin a turbine or two.
