Just fantisizing here, but helium baloons go over 50km up; can this elevator cable be vertically supported by solar-powered helium-filled heat packs alongs its way, with horizontal stabilization of large fans blowing in oposite direction (lower atmosphere) and tiny rocket boosts in above-atmosphere region similar to how sattelites correct their orbits? Just fantasizing here..
