Anything But Metric

Americans will use anything but metric

The Rules:

  1. Posts must be a screenshot, crosspost, or link to someone using a bizarre unit of measurement (33 lanes wide, as heavy as 10 semi-trucks, etc.)

  2. Standard units are not allowed, unless it's a sufficiently bizarre usage of the unit (this is up to mod discretion.)

  3. Intentionally terrible units are completely fine! Satire is welcome here

  4. Curses are fine, slurs are not. If there are slurs in something you want to post, please blur them, or reconsider posting.

  5. Flag NSFW content as such. NSFW words in these posts don't need to be censored.

  6. Post titles should be just the unit of measurement used (not the thing being measured!), and should be the full name of the unit (Apples and Bags of Apples imply very different things!) NSFW units should be partially censored. If there are multiple units, list as many as you want. If the source is satire, the title should start with [Satire]

  7. In the comments be civil, both to each other AND the subject of posts.

waste heat of 23 atom bombs a day

That actually makes the data complex a 16 gigawatt thermal load project, the “equivalent of about 23 atom bombs worth of energy dumped into this local environment every single day,” Davies said.

Those bombs would have about 14kt tnt equivalent each. tnt has about 4.18MJ/kg, so 4.18TJ/kt. 16GW over a day is 1.5PJ, so we have 330 kt per day.

This comparison will surely be useful to all designers of orion-drive style nuclear combustion power-plants.

Incidentally, tnt is about a tenth the energy density of the densest hydrocarbons, so this should take at least 30 thousand tons of oil or gas per day. And emit CO₂ on that scale. Probably more.
