Repository of problems worth solving
World Solve is a public institutional repository for identifying real unresolved problems across science, society, health, governance, economics, and local systems. Each entry is intended to be citable, inspectable, and actionable.
Publicly citable
Every problem has a stable citation code for reference and discussion.
Filtered by relevance
Search by category, geography, status, and keywords.
Builder-oriented
Use the repository to find startup ideas, policy leads, and research agendas.

The problem of flying remaining too cheap for rich people continues to affect hundreds of millions of people and undermines progress on multiple Sustainable Development Goals. Existing responses remain fragmented, under-resourced and poorly adapted to local contexts. A strong solution must operate effectively under severe constraints of skilled personnel, infrastructure, electricity and connectivity. It should define clear measurable outcomes, identify possible unintended harms, and demonstrate how the intervention can be sustained by local institutions long after initial funding ends.

Lava tubes offer natural radiation shielding for habitats, but traditional wheeled rovers cannot enter steep vertical entrances. Tethered, legged, or flying drone swarms designed for dark micro-gravity caves are needed.

Sustainable aviation fuel and electric planes exist in early forms but remain far more expensive than traditional jet fuel. Making clean flying both effective and affordable is still an open engineering and economic problem.
