You don't have to be a rocket scientist to write about rockets, but I wish sci-fi writers and futurists understood conservation of energy. They'd realize that a lot of proposed tech is fundamentally unable to fix climate for simple reasons.
Take electric cars: to move a one-ton object from point A to point B at a given speed, it takes this much energy, period. It doesn't matter how and where you produce it. And guess what: solar panels are horribly inefficient. Power distribution networks are horribly inefficient. And do you know what happens with all the energy that doesn't end up moving your car?
It becomes waste heat, that's what. Even more heat. Just what the planet needs right now. You're welcome.
