Given an inexpensive transparent material with very high tensile strength and resistance to weathering in the Martian environment, I could see a passive pressurization/thermal regulation scheme for greenhouses on the surface of Mars that relies only on, say, a heat source, some valves, and some consumable gasses. I could imagine such schemes using mainly water as an input.

That said, such a material would be asking for a lot. Then, there's also the UV and other radiation to consider.
