"I suppose being mainly CO2 means the air is heavier than on earth, but at 1% density, how big would a balloon have to be? Not to mention the heavy tank of He required to fill it."
I guess the composition of the air is largely irrelevant. If the mars air is 1% the density of earth's, then I presume to get the same lift as a balloon on earth it would need to be 100x the volume, all other things being equal. So that's about 3.2x bigger in terms of height.
