World Solve — A living repository of problems worth solving.

What World Solve is

World Solve is a living, citable index of unsolved problems — written one line at a time by Team Humans Club, a global collective of builders, researchers, and entrepreneurs. We do not solve the problems here. We Democratize Innovation.

For builders Skip the search for a problem worth your time. Browse a vetted, growing list and start where the gap is real.

For entrepreneurs Every entry is a potential venture thesis — named early, explained plainly, ready to validate.

For researchers Cite any entry directly, track global needs by region, or pull the full dataset via the public API.

We haven't figured out how to recycle electronic waste cheaply and safely at scale.

open Global / Unspecified, Global

Old phones, laptops, and batteries pile up in landfills, leaking toxic materials while valuable metals inside go to waste. A cheap, safe recycling process could turn a growing pollution problem into a resource stream.

We can't build batteries for phones and laptops that last multiple days on a single charge.

open Global / Unspecified, Global

Despite decades of research, battery capacity has improved far more slowly than the power demands of our devices. A real breakthrough here would change how we use and design nearly all portable technology.

We don't have a way to guarantee software has no exploitable security flaws before release.

open Global / Unspecified, Global

Nearly every major hack traces back to a bug that existed long before anyone found it. Catching these flaws before release, rather than after damage is done, remains an unsolved challenge.

We haven't solved how to verify online content is real, not AI-generated, at scale.

open Global / Unspecified, Global

AI can now produce convincing text, images, and video in seconds, and detection tools are struggling to keep up. Without a reliable way to tell real from fake, public trust in what we see online keeps eroding.

We can't yet build computers that are fully immune to quantum-era code breaking.

open Global / Unspecified, Global

Once powerful enough quantum computers exist, they may crack the encryption that currently protects banking, health records, and private communication. Most of the internet still isn't ready for that shift.

We don't have AI systems that reliably explain why they made a specific decision.

open Global / Unspecified, Global

Modern AI models are often accurate but operate like black boxes, even to the people who built them. Without a way to explain their reasoning, it's hard to trust them in medicine, law, or other high-stakes decisions.

We don't have a reliable way to search for signs of other civilizations at meaningful scale.

open Global / Unspecified, Global

Current searches scan a tiny fraction of the sky and only for a narrow range of signals. Without better tools, we may be missing evidence of other intelligent life simply because we aren't looking in the right way.

We can't yet detect gravitational waves cheaply enough to study them routinely.

We haven't developed weather models precise enough to predict extreme storms far in advance.

open Global / Unspecified, Global

Hurricanes and tornadoes can still shift path or intensity with little warning, leaving communities scrambling to evacuate. More precise, longer-range forecasting could save lives and billions in property damage every year.

We don't know how consciousness arises from physical matter in the brain.

open Global / Unspecified, Global

Neuroscience can map which brain regions activate during thought, but nobody can explain why that activity produces subjective experience at all. This gap separates our understanding of the brain from any real understanding of the mind.

We can't yet mine resources from asteroids or the Moon at a profitable scale.

Space contains vast amounts of metals and water that could support future industry and settlement, but the cost of extraction and transport remains far too high. Making this affordable could unlock a new resource economy beyond Earth.

We haven't figured out how to reliably protect Earth from a large asteroid impact.

open Global / Unspecified, Global

We can now detect many dangerous asteroids years in advance, but we still lack a proven way to redirect or destroy one heading for Earth. One unlucky strike could cause damage on a civilization-ending scale.

Gravity should be pulling everything together over time, yet distant galaxies are accelerating away from each other. This mystery, blamed on dark energy, remains one of the biggest open questions in physics.

Growing crops in space or on other planets means dealing with low gravity, radiation, and limited water and soil. Without solving this, any permanent settlement beyond Earth stays dependent on costly resupply missions.
