Tired of toxic smoke, a 12-year-old 'inventor' built a solar iron that could change everything for street vendors.

At 12, Vinisha Umashankar invented a solar-powered ironing cart to replace charcoal. She noticed vendors released smoke that caused lung diseases. Her creation, Iron Max, uses solar energy to reduce pollution and help merchants earn more money. She even shared her green innovation with world leaders at the COP26 summit.
