At just 18 years old, Eesha Khare, a brilliant teenager from California, stunned the world of science and technology by inventing a revolutionary supercapacitor capable of charging a cellphone in just 30 seconds.
Eesha developed the innovation while still in high school, driven by frustration over the slow charging speeds of conventional batteries. Her invention—a compact, high-performance supercapacitor—offers an ultra-fast, eco-friendly energy storage solution that could one day replace lithium-ion batteries in smartphones, wearables, and even electric vehicles.
Her groundbreaking work earned her the Intel Foundation Young Scientist Award and $50,000 in prize money at the 2013 Intel International Science and Engineering Fair (ISEF). The project instantly went viral, catching the attention of tech giants and research institutions around the globe.
- Eesha’s supercapacitor uses nano-structured materials to hold and discharge energy much faster than traditional batteries.
- It can be recharged thousands of times without significant loss of capacity.
- The technology is non-toxic, energy-efficient, and could revolutionize how we power portable electronics.
“I wanted to focus on something sustainable and efficient,” Eesha said during her award ceremony. “This could pave the way for flexible electronics and faster, cleaner energy storage.”
Since then, Eesha’s innovation has inspired a wave of green energy research. Universities and private labs are now exploring ways to commercialize supercapacitor-based charging solutions using her principles.
While commercial rollout is still in development, her invention has placed her among the most promising young innovators of her generation. Eesha’s story continues to inspire students worldwide, proving that one idea can power a future—sometimes, in under 30 seconds.
