Vehicles

Ancient Era
Because the Wyrdos essentially terraformed Mars for the Proto-Human races during their experiment, the same transportation techniques were possible as on Earth. Some labor animals were brought over and used as mounts and to help work fields and drag carts.

Modern Era
Because there is no significant oxygen atmosphere on Mars, internal combustion engines will not work. Most transportation inside the Domes is done on foot or with small electric carts, mopeds, or bicycles. Lower class citizens who grew up with body deformities also rely on wheelchairs which are mostly either hand powered or assembled from scavenged electric cart parts.

Travel outside the Domes is mostly done by electric buggies when going short to medium distances. For long distance travel or travel over rough terrain, hydrogen blimps are generally used. To help oxygenate the Domes, non potable water is extracted from the Martian soil and split into hydrogen and oxygen via electrolysis. While the oxygen is simply released into the domes' atmospheres, the hydrogen by product is used as a simple fuel inside the Domes and as a lifting gas for airships travelling outside. Because of the low-oxygen content of the atmosphere, the hydrogen gas poses no risk of explosion when utilized in this way. In addition, because of the lower gravity of Mars, the size of the dirigibles is much less than of their Terran predecessors.
