Also to put solar in perspective, current goal (which is partially achieved by FirstSolar and Nanosolar) is 1$/watt,
which would put it at 5 million even without addressing capacity or availability issues.
With addressing those issues the cost would probably rise to about ~20 million,
which I think what would cost to run a gas turbine for ~10-20 years.
Still I believe FF units could be made much cheaper if their capacity factor would be reduced to about 5 kw,
by reducing the frequency and getting rid of most cooling, shielding and maybe other systems
(maybe even use a HVDC network for powering and not a capacitor bank)?
Of course then they would be less efficient and more expensive to run,
but maybe in most applications this drawback would not be an issue.
Who cares if the electricity costs 0.01 cent or 0.001 cent per kwh at home?
Only some factories/desalinization/processing/refining and other high power usage locations should care for higher efficiency due to competition.
