It looks as though yields of over 10 times what we can currently grow per acre are feasible if you control the CO2 concentration, the humidity, the temperature, all the various factors that plants depend on to grow rapidly.

Lighter computers and lighter sensors would let you have more function in a given weight, which is very important if you are launching things into space, and you have to pay by the pound to put things there.

A potato can grow quite easily on a very small plot of land. With molecular manufacturing, we'll be able to have distributed manufacturing, which will permit manufacturing at the site using technologies that are low-cost and easily available.
