Try driving it Spike. I've been across the continental U.S. on the ground about 6 times in my life and it is huge. Then just for fun consider Russia, its almost twice as large (in land area) even without including any of the former republics.

The process is as follows --
You up the general energy conversion efficiency from solar to
something useful from ~0.1-1% for animals & plants to about 20-30%.
In the process I suspect you turn a lot of farmland back into
Use nanotech grown solar arrays to harvest sunlight at 30% efficiency, then use the electricity to split water, then use the H+ ions running across a membrane embedded with the F0F1-ATP-synthase to synthesize ATP, then use the ATP to generate all of the proteins, carbohydrates and fats you need for food.
