rtgs can be used to aid solar in charging batteries, the digging process can take a long time, if you space it correctly you would be able to get that energy fr

  No, you cannot. You are still dramatically underestimating the density of hydrocarbon energy. Solar, electric, batteries, etc do not even remotely come close. This line of thinking also dramatically underestimates the energy requirement to excavate dirt and rock... Then, figure it's on another planet with dust storms that have already killed solar-powered rovers, etc.

    > You are still dramatically underestimating the density of hydrocarbon energy. Solar, electric, batteries, etc do not even remotely come close. I never mentioned hydrocarbon energy. You keep bringing it up for some reason. > Solar, electric, batteries, etc do not even remotely come close. I don't need them to come close. I need them to do the job, and they do it > This line of thinking also dramatically underestimates the energy requirement to excavate dirt and rock... here are some electric, battery powered excavators: - https://www.volvoce.com/europe/en/products/electric-machines/ec230-electric/ https://www.volvoce.com/europe/en/products/electric-machines... - https://www.wackerneuson.cz/en/zero-emission/electric-excavators/tracked-zero-tail-excavator-ez17e https://www.wackerneuson.cz/en/zero-emission/electric-excava... - https://www.komatsu.jp/en/newsroom/2023/20230721 https://www.komatsu.jp/en/newsroom/2023/20230721 - https://www.jcb.com/en-us/products/compact-excavators/19c-1e https://www.jcb.com/en-us/products/compact-excavators/19c-1e - https://www.bobcat.com/na/en/equipment/excavators/compact-excavators/e10e https://www.bobcat.com/na/en/equipment/excavators/compact-ex... - https://www.volvoce.com/europe/en/products/electric-machines/ https://www.volvoce.com/europe/en/products/electric-machines... - https://www.hitachicm.com/eu/en/onsite/article/Introduction_to_two_new_Hitachi_electric_excavators2/ https://www.hitachicm.com/eu/en/onsite/article/Introduction_... - https://www.casece.com/en/europe/products/excavators/d-series-mini-excavators/cx15ev https://www.casece.com/en/europe/products/excavators/d-serie... - https://www.kubota.com/news/2023/20231218.html https://www.kubota.com/news/2023/20231218.html There are excavators both small and big so yes you can definetely excavate using electricity alone. > dust storms that have already killed solar-powered rovers Looking at list here https://en.wikipedia.org/wiki/Mars_rover https://en.wikipedia.org/wiki/Mars_rover I guess you talk about Zhurong and Opportunity? Both of these seems like success story given that they survived way longer than they were expected to..

      Just wanted to add to your list, electric dozers have been on the market for some time. Even more impressive given the weight. https://www.cat.com/en_US/products/new/equipment/dozers/medium-dozers/15969752.html https://www.cat.com/en_US/products/new/equipment/dozers/medi...

        And how do we get a 51,333 lb bulldozer to Mars? Not to mention this bulldozer still burns hydrocarbons. It uses electric drive for it's tracks - and the electricity is generated by hydrocarbons!
