During the 2021 United Nations climate summit in Glasgow, however, one of the most widely discussed speeches came from someone who was not a politician, scientist or business leader. Instead, it was delivered by a 15-year-old school student from Tamil Nadu, India, whose practical invention had already drawn international attention. Vinisha Umashankar had developed the idea of a solar-powered ironing cart designed to replace the charcoal-fired carts used by many street ironing workers. What began as a school-age innovation soon travelled far beyond local communities, earning awards in India and overseas before placing its young creator before an audience of world leaders at COP26, where she spoke about the need to accelerate the shift towards cleaner energy sources.Vinisha Umashankar was a Class 10 student from Tiruvannamalai district when her idea attracted national attention.
Rather than focusing on a futuristic technology, she looked at a familiar sight across many Indian towns and cities: roadside ironing carts heated with burning charcoal.These carts provide an important livelihood for thousands of workers, but they also depend on a fuel that creates smoke, consumes coal and exposes operators to heat throughout the working day.Vinisha began thinking about whether the same job could be carried out using renewable energy instead. Her proposal centred on a mobile ironing cart fitted with solar panels capable of powering a steam iron, reducing dependence on charcoal while allowing the service to remain portable.The idea received support from the Innovation Foundation (NIF) – India, an autonomous organisation under the Department of Science and Technology, Government of India. In 2019, the foundation developed a working prototype based on Vinisha's concept.The cart was designed to use solar energy as its primary power source while remaining flexible enough to operate under different conditions. When sunlight was unavailable, it could also run using pre-charged batteries, electricity or even a diesel-powered generator, ensuring workers would not lose business because of changing weather.The design reflected the realities faced by people earning a daily income rather than assuming ideal conditions throughout the year.The project was intended to offer more than cleaner energy.
