> Energy density can be both important for transportation and also be important for the ability to accelerate energy production without a proportional growth in mining/resource harvesting that harms the planet.
>A melon sized chunk of uranium powers an Aircraft carrier of the US navy for over 2 decades while it circumnavigates the globe hundreds of times, launching aircraft off its deck and powering remarkable levels of energy demand from on board systems.
You've made a bit of a mistake here, thinking that energy density and resource harvesting are always opposed. They're not. The aircraft carrier uses 93% HEU, while most reactors use uranium that is 10-20x less enriched. The same amount of earth has to be mined either way, but the HEU used in the core of an aircraft carrier or nuclear sub has to undergo a lot more expensive and resource intensive (and downright dangerous) post-processing.
