Something you can actually pick up

With Team Gaia at Atria University, I helped design and build a terracotta-based cooling product for Solar Decathlon India.

My work covered brainstorming ideas, designing the product, choosing materials, and making the physical product. It was an opportunity to work through an engineering problem with materials in hand.

We finished runner-up in the Residential Cooling Retrofit division at Solar Decathlon India 2025.
