In a world increasingly focused on renewable energy, young innovators are making a big impact. One such remarkable young mind is Hannah Herbst, a teenager from Florida who developed the Ocean Energy Probe—a device that harnesses ocean currents to generate sustainable electricity. Her invention has the potential to provide affordable and clean energy to communities with limited access to power.
Who Is Hannah Herbst?
Hannah Herbst’s journey as an innovator began with a desire to help those in need. She was inspired by her pen pal in Ethiopia, who faced frequent electricity shortages. Determined to find a solution, she created a low-cost, renewable energy device that could make a real difference in people’s lives.
In 2015, at just 14 years old, she won the Discovery Education 3M Young Scientist Challenge, earning the title of America’s Top Young Scientist for her groundbreaking invention.
How Does the Ocean Energy Probe Work?
Hannah’s Ocean Energy Probe is designed to generate electricity by harnessing the kinetic energy of ocean currents. The device consists of a floating system equipped with a propeller and a generator. As ocean water moves, it spins the propeller, which then powers the generator to produce electricity.

Unlike fossil fuels, which contribute to pollution and climate change, Hannah’s invention provides a clean, renewable energy source. The probe is also cost-effective and can be implemented in coastal areas where access to electricity is limited or unreliable.
The Importance of Hannah’s Innovation
Hannah’s invention addresses several key global energy challenges:
- Sustainability: The probe generates electricity without emitting harmful greenhouse gases.
- Affordability: It provides a low-cost alternative to solar panels and wind turbines.
- Scalability: The design can be adapted to various locations and energy needs.
- Accessibility: It offers a practical energy solution for remote and off-grid communities.
Recognition and Future Prospects
Hannah’s work has received national recognition, but her journey doesn’t stop there. She continues to advocate for STEM education and inspire young scientists to explore renewable energy solutions. With further research and development, the Ocean Energy Probe could be scaled up to generate even more power, contributing to the global transition toward clean energy.
