At the Earth's distance from the Sun, at 100% conversion efficiency, you could only produce 1 gram of matter per square meter of captured sunlight every 2000 yrs. In other words, it would likely take millions of years just to break even on the mass needed to build the capture and conversion facility.If we could capture energy from the sun or interstellar space and convert it efficiently into matter perhaps we could ensure a steady supply or resources for future generations as we colonize space.
