The 1cent/kWh threshold is likely to be first reached by doldrum-sited
atmospheric vortex engines at $400/kW CAPEX and very little OPEX.  See slide
3 <http://vortexengine.ca/PPP/Development_Plan.pdf> item "Stand Alone
Maritime Tropical AVE".  The CFD model refinements Thiel has
funded<http://www.vortexengine.ca/misc/breakout-labs-power-a-city-grants-dec-2012.pdf>are
under way now.  Even under CFD-naive pessimistic assumptions of
turbulent flow -- pessimism that does not appear to be borne out by
observations of natural analogs such as water spouts -- 3cent/kWh looks
achievable in the doldrums.  The remaining economy is achievable by
applying in situ electricity to converting ocean minerals and atmospheric
CO2 into graphene-oxide reinforced concrete via
MAP<http://dev.calera.com/index.ppp/technology/electrochemistry/index.html>and
other processes.  Doubling time of such doldrum AVEs using in situ
derived structural materials appears to be on the order of a year and
possibly less.

Of course, at that point, the main market served will not be gasoline but
real estate in the form of tropical beach front
condos<http://www.shimz.co.jp/english/theme/dream/greenfloat.html>as
people migrate to where the jobs, and fun, are.
