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.

Automated financial, information, military, and infrastructure systems may act in milliseconds while democratic institutions deliberate over months. The challenge is designing pre-authorized constraints, real-time oversight, and meaningful accountability. The solution must work with limited capital, intermittent services, and local maintenance capacity. The research opportunity is to define measurable success criteria, test the approach in realistic settings, identify failure modes, and create a pathway from prototype to accountable deployment.

Future cities may depend on private platforms operating transit, energy, housing, communication, and public-space services. Strong public-interest rules are needed when essential services are controlled through private systems. The solution must work with limited capital, intermittent services, and local maintenance capacity. The research opportunity is to define measurable success criteria, test the approach in realistic settings, identify failure modes, and create a pathway from prototype to accountable deployment.

Building one app that works well across many different operating systems and device types often results in compromises that make it less polished than a dedicated, platform-specific version. Fully closing this quality gap remains an unresolved software engineering tradeoff.

While ion drives are fuel-efficient, their low thrust-to-weight ratio means orbital transfers take months or years. High-power, magnetoplasmadynamic thrusters operating at the multi-kilowatt level are needed.
