How did your collegiate project on Stirling engines lead to developing EV battery packs?

My co-founder Swapnil Jain and I spent years experimenting with Stirling engines powered by ambient heat. While those early experiments did not yield a commercial company, they solidified our commitment to the clean energy space. After graduating, I filed a patent on battery pack architecture for electric cars, quickly realizing that India's urban traffic dynamics made electric two-wheelers a far more viable and urgent market.
