Teens Invent Salt-Powered Fridge, Transforming Rural Healthcare

Quick Smiles: Three inventive teens from India have crafted a unique fridge that requires no electricity, using the power of salt. Their creation, Thermavault, is set to revolutionize rural healthcare by keeping medical supplies cool without traditional power sources. With 200 units headed to hospitals for testing, these young innovators have already earned the prestigious […]

Some stories ignite your heart like a bright spark in the morning sky, and this article about three teens inventing a salt-powered fridge is one that’s got me positively glowing!

I’m just bubbling with excitement thinking about Dhruv, Mithran, and Mridul, high schoolers from Indore, India, who saw how hard it was to get COVID vaccines to rural villages without power and said, “Let’s fix this!”

It’s so uplifting to know they created the Thermavault, a little fridge that uses ammonium chloride and water to stay cool for 10 to 12 hours, no electricity needed—just a clever mix of salts that suck up heat like magic.

I love how these boys, kids of doctors themselves, tested 150 salts with their professor, Mobin Shaikh, to build a box that can keep vaccines or even transplant organs safe, and now they’re sending 200 of them to 120 hospitals with their $12,500 Earth Prize money.

The way their invention could save lives in far-off places, all while being reusable by boiling the salt back to life, makes my soul sing. This story lifts me up because it’s a shining example of young minds, driven by care and ingenuity, turning a simple idea into a lifeline for communities that need it most.
