imagine if we could harness the power of the sun and basically direct extra heat towards target moons and planets via a mirror system or something and basically make any body in our solar system human habitable warm. I'd imagine this could also be weaponized against dangerous asteroids, as the heat laser or whatever could cause a change in direction.
