As someone more knowledgeable, do you have any insight in what would be necessary to grow food in space (with or without gravity), and how we could "prepare" for that (i.e. develop and test the technology)? That's my main interest in "indoors" technology - how does the viability, and the economics, change when "land" and power become cheap (plenty of solar in space) but transport (delta-v) is crazy expensive...
