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.

When dreams are scored, shared, and sold like social content, intimate mental experiences become competitive and commercial. The problem is protecting the private, non-instrumental nature of dreaming while still permitting voluntary creative or therapeutic uses.

If drinking water carries detectable flavour differences linked to the political stance of the provider, basic hydration becomes a partisan signal. The challenge is maintaining truly neutral, safe water access independent of ideological branding or corporate affiliation.

Statues that continuously change expression or posture according to live public sentiment risk turning monuments into unstable opinion mirrors. The problem is allowing cultural responsiveness without erasing the original historical record or creating permanent contention over every figure.

Urban platforms that reposition based on market indicators create unpredictable geography, disrupt supply chains, and separate communities. The problem is coordinating mobility, infrastructure continuity, and resident rights when the ground itself moves for financial reasons.

Smart textiles that adapt to and then lock in a wearer’s patterns can limit self-expression and create unwanted permanence. The challenge is designing garments that learn usefully without removing the wearer’s ability to change appearance or discard unwanted adaptations.

Windows that show personalized or algorithmically chosen realities fracture the common visual environment. The problem is preserving enough shared external reference for coordination, safety, and social cohesion while still allowing beneficial personalization.

When digital systems fail, public trust in records, payments, and eligibility can collapse. The challenge is designing governance that can preserve continuity, recover data, and verify truth across technical interruptions. This becomes particularly difficult in informal settlements, because public institutions must remain fair, resilient, and accountable while adapting to new risks.

When collective memory of shared events is rewritten in real time by majority vote or algorithmic consensus, no stable historical baseline remains. The problem is creating durable, independently verifiable archives that coexist with participatory updating without being overwritten.

If individuals can alter gravity in their private environments, public areas must still enforce uniform conditions for safety and fairness. The challenge is preventing spillover effects, health disparities, and social stratification based on access to customized physical laws.

When corporations patent forms of rainwater collection or composition in water-scarce areas, ordinary puddles and runoff become potential infringement sites. The challenge is designing water-rights frameworks that protect both innovation incentives and the basic human need for free access to precipitation.

When people rent out unused cognitive capacity during daydreaming, buyers may leave behind persistent mental traces. The problem is creating clean separation between leased neural resources and the host’s own cognition so that temporary economic use does not produce lasting psychological or identity effects.

If facial appearance can be altered continuously through filters or implants, both social recognition and security systems lose stable anchors. The problem is maintaining trustworthy identity verification and human connection without requiring permanent biometric locks that themselves create new risks.

Metering park entry according to measured oxygen use could exclude people with higher metabolic needs or certain health conditions. The challenge is creating inclusive green-space access rules that still manage environmental impact without turning basic recreation into a health-based barrier.

If sleep becomes a tradable commodity sold in discrete blocks, the poorest citizens may be forced into permanent light or irregular cycles. The challenge is designing access systems that treat restorative sleep as a basic need rather than a market good, while still allowing voluntary exchange for those who choose it.

When local weather can be bought in advance, wealthier areas may secure preferred conditions while poorer ones experience residual or adverse patterns. The challenge is creating equitable allocation mechanisms for atmospheric resources that do not deepen existing social divides or disrupt larger climate systems.

When personal memory archives exist solely in distributed cloud systems, sudden or gradual data loss can erase formative experiences without local backups. The challenge is building durable, verifiable, and accessible long-term personal memory infrastructure that survives corporate failure, format obsolescence, and account lapses. Solutions should remain affordable, user-controlled, and recoverable even decades later.

As digital navigation layers become permanent fixtures in daily life, physical landmarks lose meaning and people lose the ability to orient themselves without screens. The challenge is creating systems or practices that preserve spatial awareness and independent wayfinding while still allowing beneficial digital tools. Solutions must work across cultures, age groups, and infrastructure levels, avoid creating new dependencies, and remain usable when networks fail.
