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.

Direct air capture exists, but it's still far too expensive and energy-intensive to make a dent in global emissions. Making it cheap enough to scale is one of the biggest levers left for slowing climate change.

For decades, computer chips got faster mainly by shrinking transistors, but they're now near the smallest physically possible size. Finding a new way to keep computing power growing is an open engineering problem.

When an AI makes a harmful decision, it's often unclear whether the blame falls on the developer, the user, or the company deploying it. Without clear rules, victims of AI mistakes often have no clear path to accountability.
