A general purpose micromechanical clanking replicator, (call it a Jeep McRep? Micro-Mech Cee aRR, micromaker? Clank-R? Clanker, jeep clanker works for me) is meant to make all the parts to make all the parts from raw inputs in the most brute force ways I can imagine, including elemental deposition. If we imagine something designed to refine, shape, mill, bend and additively manufacture in a hundred different processes with a hundred different machines which in turn can be used to ramp up to a thousand or ten thousand processes I can imagine a ton of stuff processing a tonne of ore into 10 kg of stuff every day on, say, 24 KW-hr of solar power, which is 1%/day, 100%/100 days. Presumably it could adapt production to make more of whatever is most efficiently processed, refined and manufactured to get this up to 100 kg of stuff from one tonne of ore in about 30 days time, adding new physical plant to get to a couple tonnes of clanker spread out over ten or a hundred times as much space. Even if it’s replacing itself every month it could still reprocess and produce three tonnes less a couple tonnes of clanker which still leaves a tonne of stuff free and clear, 100 kg/day per 2 tonnes of clanker after one month of optimization on site with 900 kg of waste we can repurpose, some of which is O2 if the feedstock is aluminosilicates on the Earth or the Moon, and some of which may be hydrocarbons and water on the Earth or in the asteroids. The clanker could keep doubling capacity every month while outputting half a tonne/per tonne of goods or switch to a tonne of goods per tonne of clanker and doubling every other month. If this is 50% compounded monthly that’s over 100 fold after a year, over two million-fold after three years.
