Part 3/11:
In mobility applications—specifically electric vehicles and aircraft—batteries and structural frames rank among the heaviest components. Merging these functions could drastically reduce weight. Consider a scenario where structural batteries allow us to achieve two components for the weight of one, which would help break the vicious cycle of weight and energy requirements. However, it's crucial to clarify that these batteries are not actually "massless"; instead, they illustrate an innovative approach to solving inherent challenges in energy storage and mobility.
