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.

People often prefer clear narratives and resolution, even when it means adopting interpretations that aren't fully supported by the actual evidence available. This unresolved tension touches on both personal psychology and the broader ethics of belief formation.

Excess natural gas at oil extraction sites is often simply burned off rather than captured and used, wasting a valuable resource while releasing preventable emissions. Capturing this gas instead of flaring it remains inconsistently adopted across the industry.

Sustainable building materials often cost more or aren't as widely available as traditional concrete and steel, slowing their adoption across the construction industry. Making green materials the default rather than the premium choice remains unresolved.

As electric vehicle adoption grows, local power grids in many areas aren't yet built to handle the sudden, concentrated demand spikes from many vehicles charging simultaneously. Upgrading this infrastructure fast enough remains an unresolved challenge.
