Inspired by Blackouts in India, Young Girl Develops Low-Cost Renewable Technology with Piezoelectric Material and Wins International Award by Proposing Solution to Global Problem
In a global scenario marked by energy crises, climate change, and challenges in electricity supply, a young American girl of only 13 years caught the world’s attention by presenting a surprisingly simple and economical solution. Maanasa Mendu developed a device capable of generating clean energy for approximately R$ 16, showing that innovation does not depend on age — but rather on purpose, creativity, and applied science.
The information was reported by the BBC, according to a report published on October 28, 2016, with data provided by Discovery Education, the organization responsible for the scientific competition that awarded the young inventor.
How the Clean Energy Device Created by Maanasa Mendu Works
Maanasa Mendu won a young scientists competition in the United States and received a prize of US$ 25,000 (about R$ 80,000) by presenting the device called “Harvest”, which means “harvest” in English. The device captures energy that is constantly available around us and transforms it into clean electricity.

According to Mendu herself, she explained on the BBC’s Newsday program:
“The device captures the energy that is constantly available around us to create clean energy.”
Initially, the young girl intended to focus exclusively on wind energy. However, with the guidance of her mentor, engineer Margaux Mitera, she expanded the project and began to integrate other natural sources such as:
- Solar energy (through small solar cells)
- Wind energy
- Energy generated by precipitation
Additionally, the device uses a piezoelectric material capable of converting mechanical force into electricity. This material, when coupled with the device, generates energy from natural movements in the environment.
Although the prototype was still rudimentary in its initial phase, it fulfilled its main objective: to produce renewable energy simply, functionally, and at a low cost.
The Inspiration: Recurring Blackouts and a Global Problem
The motivation to develop the device arose during a trip to India. Every year, according to Maanasa, her family faces recurring blackouts in the country.
“For me, this means temporarily not having access to air conditioning or electricity. But for over one-fifth of the world’s population, blackouts are a permanent reality,” she stated.
This data is crucial. While many people deal with temporary power outages, a significant portion of the world’s population lives without constant access to electricity. Therefore, the proposal to create an accessible and sustainable lighting system is not only innovative — it is urgent.
Furthermore, while piezoelectric technology is not new, interest in this type of solution has been growing in recent years. Experts see this technique as a possible alternative to tackle long-term energy supply challenges.
Scientific Competition and International Recognition
Maanasa competed with other nine finalists in the competition promoted by Discovery Education. Among the projects presented were:
- Bacteria that generate energy
- Sensor to assist people with physical difficulties
- CPR simulator
- Device for pollution control
Still, the young girl’s project stood out by uniting social impact, sustainability, and economic viability.
Bill Goodwyn, the CEO of Discovery Education, highlighted the spirit of the competition:
“Each year, this competition reminds us of the inspiring ingenuity we gain by putting our younger generation to apply science, critical thinking, and creativity with the goal of suggesting solutions to real-world problems.”
After winning the award, Mendu stated that she plans to develop a more complex prototype with commercialization potential. In other words, the project can evolve from a school experiment to a large-scale applicable solution.
Youth, Science, and Real Impact
The story of Maanasa Mendu reinforces an essential point: young scientific talents can turn global problems into opportunities for innovation. Moreover, when science, critical thinking, and creativity walk hand in hand, solutions emerge that benefit millions of people.
Her clean energy device costing only R$ 16 represents much more than an awarded experiment. It symbolizes hope for regions affected by blackouts and reinforces the importance of technological education from an early age.
If a 13-year-old girl can propose a sustainable alternative to the global energy problem, what else can the new generation create in the coming years?
