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.

Cryogenic liquid propellants boil off rapidly during long-term orbital and interplanetary storage.

open Global / Unspecified, Global

Hydrogen and oxygen boil off due to solar radiation in orbit, prohibiting long-duration storage for deep space stages. Advanced active cryocooling, sunshields, and zero-boil-off insulation technologies are required.
