Techniques designed to maximize the yield of desired resources (water, metals, volatiles) from raw materials (ore, regolith, atmosphere) while minimizing energy input, waste, and environmental footprint. In space, efficiency is survival—every joule of energy and kilogram of mass is precious. Methods include in-situ resource utilization (ISRU) like using solar ovens to bake oxygen out of lunar soil, electrochemical processing of asteroid ore, or passive wind-traps to collect atmospheric moisture on Mars.
Efficient Extraction Methods Example: The MOXIE experiment on the Mars Perseverance rover, which uses electrolysis to efficiently extract breathable oxygen from the carbon dioxide-rich Martian atmosphere, is a prototype Efficient Extraction Method. On the Moon, using concentrated sunlight to thermally reduce ilmenite ore for iron and oxygen is another, as it uses abundant solar energy instead of imported chemicals.

Get the Efficient Extraction Methods mug.The cognitive bias where one assumes that their preferred measures of efficiency are simply "efficiency"—neutral, objective, universal—while dismissing other measures as irrelevant or biased. Efficiency Bias is what makes businesspeople assume that profit measures efficiency, that what's good for the bottom line is what works. It's what makes policymakers assume that cost-benefit analysis captures all relevant values. Efficiency Bias treats one construction of efficiency as the construction, one perspective as the perspective. It's the favorite bias of those who benefit from current definitions of efficiency, who don't want to ask "efficient for whom?"
Example: "He presented the profit numbers as proof of efficiency. Efficiency Bias meant he never had to consider environmental costs, worker well-being, community impact. His measure was the measure; everything else was secondary. When she pointed out what was excluded, he dismissed her concerns as 'not relevant to efficiency.' The bias was invisible to him, which is how it worked."

Get the Efficiency Bias mug.The application of perspectivism to efficiency—the view that efficiency is always seen from a perspective, never from nowhere. Efficiency Perspectivism argues that there is no view-from-nowhere efficiency, no neutral measure that captures how well things work for everyone. Every efficiency claim comes from somewhere, serves some interests, reflects some values. The task is not to find the one true efficiency but to understand different perspectives, to see how efficiency looks from different positions. Efficiency Perspectivism is the philosophy of pluralism in evaluation, of the recognition that how well something works depends on who's asking.
Example: "He'd thought there was one way to measure efficiency—the right way. Efficiency Perspectivism showed him otherwise: efficiency looked different from different perspectives. From management, it was about output; from labor, about working conditions; from community, about local impact. None was the truth; all were true from somewhere. He stopped looking for the one measure and started learning to see from many angles."

Get the Efficiency Perspectivism mug.The application of contextualism to efficiency—the view that what counts as efficient varies with context, that there is no context-independent standard of efficiency. Efficiency Contextualism argues that a practice efficient in one context may be inefficient in another, that measures that work in some situations fail in others. Efficiency is always efficiency-in-context, never efficiency-in-itself. The theory calls for attending to context, for asking not just "is this efficient?" but "efficient in what context, for what purpose, under what conditions?"
Example: "The management technique had worked brilliantly in the tech startup. When applied to the hospital, it was a disaster. Efficiency Contextualism explained why: context mattered. What was efficient in one setting was destructive in another. He stopped importing solutions without asking whether the context fit."
