High-Level Project Summary
Using the data from the Mars rover, we sized a graphene-based battery to power the rover, based on the data that the rover needs 100watts to roam, so we sized a 110-watt battery, calculating its weight from the density energy and finally calculating its volume from the density of the material, and consequently its dimensions, using graphene we obtained a battery 5.5 times more efficient than conventional lithium batteries.

Hackathon Journey
We did it for love, we liked our work and we liked the idea of improving the world through it, the choice of challenge was controversial in the beginning and a half, it seemed foolish to even try such a feat, however we had persistence in our goal and we managed to deliver a great solution
