[Spaceships] Martian “Gas” Station

[DaltonS]

This base is a refueling station for vehicles travelling to, from, on and over Mars. It was built on a frozen underground aquafer which is mined for ice to be melted (water itself is precious here) and refined into LOH fuel (for rockets and fuel cells) and pure hydrogen for use as reaction mass, lifting gas and feedstock for producing methane (also used as reaction mass). It also sells surplus food from its domed greenhouse and hydroponics bay and serves as a trading post, clinic and government center for other settlers on the red planet.

User Notes: This “Gas” station mines ice from a frozen underground aquafer which is turned into hydrogen (for reaction mass or lifting gas) or LOH (for fuel cells or rockets) by different chemical refineries. The hydrogen is also used as feed stock for a third refinery that produces methane (reaction mass) with carbon dioxide in the Martian atmosphere.

My starting point was "The Warren" from Pyramid 3/71, page 11 but I have made extensive changes. The Mars Trans-Orbital Taxi is my own design. Unfortunately the Solar Power Options feature isn't working when I set the "Stellar Distance" to 1.5 AU so my Solar Panel Arrays aren't contributing to the power budget. (They would add 1⅓ power points if they did.)
