NASA Inventor's Waterless Toilet Reaches 20,000 Families

One billion people worldwide live without access to flush toilets or sewage systems. For them, a NASA engineer just created something that could change everything.

Diana Yousef was designing bathrooms for space stations when she had a revelation. Astronauts and people living beyond the reach of plumbing face the exact same problem: no way to flush waste with water. Both need toilets that work without pipes or sewage systems.

Her solution is the iThrone, a waterless toilet that rapidly evaporates 95% of the liquid content in human waste. The standalone units can be dropped into any environment, making waste disposal safer and more manageable in areas that traditional plumbing can't reach.

The technology is already deployed in Uganda, Panama, and the United States, serving 20,000 households. The design is straightforward and replicable, built to work anywhere without complex infrastructure.

Yousef holds degrees from Cornell, Columbia, and Harvard. She founded the startup change:WATER to bring her invention to communities that need it most.

The Ripple Effect

This year, Yousef received the Global Citizen Waislitz Award for advancing innovative solutions to global challenges. The $100,000 prize will help change:WATER scale iThrone distribution dramatically.

By next year, Yousef plans to reach millions more people. Her mission goes beyond solving a technical problem: she's working to make safe, sustainable sanitation possible for everyone, everywhere.

The toilet that started as a space station solution is now addressing one of Earth's most pressing humanitarian needs. What astronauts require in orbit turns out to be exactly what a billion people need on the ground.

Safe sanitation transforms communities by reducing disease, protecting water sources, and restoring dignity to daily life. The iThrone proves that sometimes the most earthbound problems need solutions designed for the stars.
