The idea of increasing per-capita energy consumption to 1,000x current American levels is so ludicrous Andreesen should immediately be laughed out of town without any further consideration.

I did some back of the envelope calculations (and obviously made a few assumptions about what he meant), but, roughly, 1,000x current US per capita energy consumption is about enough to keep you airborne in a (fully occupied) corporate jet continuously with fuel synthesised from air and water.
