Hot showers are a truly amazing luxury. Historically not even the wealthiest people on the planet have had access to them. It’s a nice thing to think about when it’s 0 degrees outside and you’re taking a shower for probably a few pennies of water and electricity.

It's somehow strange because in any sunny place, all you need to have hot showers is a black surface tank. Could have been done very long ago at scale.

  In sunny places that either aren't too cold or have access to high quality transparent insulation.
