  And what’s wrong with that? Who says the coal has to be a net source of power?

  Synthetic fuels are actually a pretty viable method of decarbonizing, especially for hard-to-decarbonize applications like aviation. Sure, you don’t get net energy out of them, but who cares? Thanks to dirt cheap solar, our civilization has stupidly abundant access to energy. It’s only portable energy or energy when we want it that costs a lot. But people have seriously proposed making even gasoline from atmospherically derived carbon. Sure, it’s just a fancy battery. But the Joules/dollar you get from the grid is so much cheaper than what you get from gasoline that it may be worth it.

    Wouldn’t be carbon neutral.

    /dollar is a fantasy bullshit metric. Joules portable per joule in, joules per weight, joules per area, chemical byproducts per joule, fancy gear and maintenance required. those are what actually matter in the real world. We cannot afford to keep fucking around with childish LARP shit like money.

    And the best tool we have for carbon capture is still just trees.

      It could be carbon neutral. It’s all about how you do it.

        In some convoluted process where you output a bunch of other stuff; sure.
