World Solve

Future progress on human development and planetary health depends on solving clean cookstoves not scaled. Conventional approaches have proven insufficient. The required intervention must integrate community knowledge, data and appropriate technology while remaining affordable, privacy-preserving and operable with minimal external support. Strong solutions will articulate measurable impact metrics, risk mitigation strategies, and a plan for sustained operation by local actors after the pilot phase.

Informal settlements often sit in floodplains, and drainage infrastructure has not scaled with urban growth. Low-cost flood-mapping and early-warning apps could reduce casualties.

Miniaturized satellites often burn out early because standard thrusters are too large or heavy for 1U-6U form factors. Micro-electrospray and green propellant systems must be scaled up for commercial CubeSat fleets.

Major textile production centers generate vast amounts of fabric offcuts and synthetic water pollutants that end up in landfills or local ecosystems rather than being recycled into new textiles.

High real estate costs and energy requirements hinder vertical farming and aquaponics from providing cheap, fresh produce to low-income urban populations.

Millions of children are taught in non-native national languages, hindering early literacy. Digital tools lack high-quality speech recognition for under-resourced regional dialects.

Standard lithium-ion battery arrays suffer accelerated degradation in tropical ambient temperatures, making grid-scale battery storage prohibitively expensive.

Developing Asian countries spend more on servicing foreign debt than on climate adaptation. International financial institutions have not scaled debt swaps effectively.

Commercial seaweed farming faces high initial equipment costs and fragile processing supply chains, delaying its potential for carbon sequestration.
