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.

Miniaturized satellites often burn out early because standard thrusters are too large or heavy for 1U-6U form factors. Micro-electrospray and green propellant systems must be scaled up for commercial CubeSat fleets.

In archipelagic nations like the Philippines, vulnerable households repeatedly lose livestock, crops, and home infrastructure to severe seasonal storms. Standard microfinance models often default during disasters, compounding debt cycles rather than relieving poverty.
