Propulsion in Tristan da Cunha: None Industrial

Tristan da Cunha (remote South Atlantic volcanic archipelago) has no industrial propulsion systems.

Its ~250 residents rely on:

• Fishing boats (diesel outboard/inboard)
• Small generators (diesel) for electricity
• Supply ship (MV Edinburgh or chartered vessels) visits ~6–12x/year from Cape Town

No airport, cars, or heavy machinery. Transport is walking, ATVs, or small boats. "Propulsion" in any advanced sense doesn't exist.
