Backup
Put the candle in more than one room.
Cool thinking machines in ice, under the sea, and in vacuum. Practice a house off the one peninsula. Grow loops with bacteria and fungi — licensed labs. One world is one candle. A strong wind can take it.

Sea analog
The other room is already here.
Pressure, dark, and closed-loop life support exist in the ocean before they exist on Mars. We teach ice, sea, and space as one literacy — simple enough for a school day, hard enough for a lab.

Living systems
Fungi helped plants onto land.
Fungi reached land before trees. Mycorrhizae fed the first plants. Land plants later pulled carbon from the air. The first great oxygen rise was older still — cyanobacteria, about 2.4 billion years ago. Lesson: living partners can change a world’s air, slowly, at planetary scale. We study that analog with licensed labs. We do not rewrite Earth’s sky in a garage, and silicon does not grow lungs.
- Labs
- Licensed partners only
- In-house pathogens
- None
- Use
- Closed-loop habitat literacy

Ice / space analog
Backup is a practice.
Ice took houses that thought they were strong. Polar and habitat analogs teach that survival is logistics, not a speech. Depths does not claim a fleet. It claims a curriculum that can travel.
- Sites
- Ice, sea, space analog
- Audience
- Public + K–20
- Not
- A private nation

Cooling the minds
Thinking machines make heat. Ice, sea, and space take it.
A data hall already sinks heat into water. Polar air is a sink. Space radiates heat to the dark. We train people to keep servers and habitats alive in those rooms so a house can live off the one peninsula. Harsh weather is the same literacy as a multi-world house.
- Rooms
- Ice, sea, vacuum, heat
- Use
- Servers + life support
- Not
- A claimed fleet
