Used for excavation of lunar and asteroid surfaces the Ice Harvester, built by
the CAT corporation, is critical to supporting life in space by providing oxygen
for breathing and hydrogen for fuel. It chews up the upper layers of crust using
the rotating cutter head. The crust material is then fed through the throat of
the cutter head and into the processing area of the harvester where is is finely
ground. The ground material is passed under two radiant heating units to
evaporate water and ice for collection. The evaporated water is drawn upwards
through the condensation towers where it is cooled to liquid form. The remaining
crust material is discharged through the rear of the harvester. The liquid is
them pumped into the holding tank for storage and transport.

| (...) This is just way too cool! Kudos for the extra pictures showing some construction details also. What are the two Lego pieces that the front assembly attaches to? (URL) -mark (18 years ago, 31-Jul-06, to lugnet.space, FTX)

| OMG. Well, instead of just drooling like a moron, I should say something. I particularly like you attention to minifig details, like the ladders, guard rails, and non-slip floors. Color me inspired. (18 years ago, 31-Jul-06, to lugnet.space, FTX)

| Actually, I do have a suggestion. Most lunar environments, as scientific observation has informed us, are somewhat lacking in breathable oxygen. Since they don't have an atmosphere to speak of. Thus, I recommend helmets and airtanks for your pilots, (...) (18 years ago, 3-Aug-06, to lugnet.space, FTX)
