Episode notes
Water Problem and Early Understanding
- The problem with most of Earth's water is that it is salty and not useful for drinking or farming.
- Humans have known for millennia that seawater can be turned into fresh water, but it was historically difficult to do at scale.
Ancient Distillation Practices
- The ancient Greeks, including Aristotle, documented seawater distillation around the 4th century BC.
- Old sailors boiled seawater and captured steam to drink fresh water on voyages, though this yielded little and consumed much fuel.
1560 Spanish Siege Desalination
- In 1560, Spanish forces built the first known land-based seawater distillation plant in Tunisia during a siege.
- It boiled seawater over open fires and captured steam to provide fresh water under harsh conditions.
