At a science fair in Lagos, Nigeria, four teenage girls stunned the world with their urine-powered generator—an eco-friendly invention that can generate six hours of electricity using just one liter of human waste. The system extracts hydrogen gas from urine, purifies it, and uses it to power a modified generator. Their project showcased not just creativity, but a brilliant solution to energy scarcity using an overlooked and abundant resource.

In regions where fuel is expensive or unreliable, innovations like this can revolutionize access to power—especially in off-grid communities. The invention also draws attention to the potential of young minds in shaping a greener future. These girls proved that sustainable energy doesn't always need high-tech labs—it just needs bold thinking and resourcefulness.
