Basic Rocketry - Getting Fuel for Steam Engine

I am building rockets in space (vaccum) so CO2, heat and steam will dissipate very fast.
Build the steam room near your rocket engine and at the edge of the Vacuum (space exposure) but not in it. Meteors will provide regolith at +200 Celsius degrees which is enough to heat buncker doors to get steam. When regolith is below 100 Celsius degrees, mine it and wait for other meteor to strike.

• 2 Bunker doors – they absorb regolith heat and transfer it into the room.

• Walls – Insulated tiles – ingenoius rock

• 1 Airflow Tile- steel (you can replaceit with insulated tile)

• 2 Gas Pumps – steel (one is enough if you don’t have steel)

• Manual Airlock – steel

• Liquid Vent – steel

• Gas Pipes or Insulated Gas Pipes – It doesn’t matter because after few rocket launches their temperature will be above 100 Celsius degrees. Just don’t build them inside walls

• Insulated Liquid Pipes – use them to get water for the steam

• Thempshift Plate – Any material with thermal conductivity (Iron will do it)

You can use water (evaporation point 99.4 Celsius Degrees) or polluted water (evaporation point 119.4 Celsius degrees).

• Atmo Sensor – steel - Activate if bellow 20000 grams.

• Hydro Sensor – steel – Activate if bellow 100 kilos. probably Hydro Sensor and And Gate aren't a must. I think just Atmo Sensor is enough.

• And Gate – I used steel (I think iron will do it). It controls the liquid pump used to deliver water.

• Automation wire – I used steel (I think iron will do it)

Connect gas pumps with your steam engine and lock the door. The pressure in the room will be over 20 kilos all the time. I am using the steam rocket to get materials from asteriods in 10000 km range.

Enjoy, rate and leave feedback. Thank you.
