While you do have a point that animal life is not solar powered, only by proxy, using vegetables as fuel, so would our machines not be solar powered, only by proxy, using a vast network of solar arrays as energy. Thus, as, let's say, a gazelle needs, let's say, 1ha of grassland to live, so would a car need 1ha of solar panles to move. On the other hand, I agree, I see fusion as the future and I think it is necessary if we want to meet the future demand for energy. I'd also love for us to become a space faring civilization, and for that, we need to be able to make our own little sun. We'd then be able to build our own self-contained solar system. After all, if you look further enough down the chain, all energy we're using is solar. Yet, if you look even further down the chain, all energy is fusion.
