I don't see how pv will ever be able to compete with a closed cycle
engine with a dish reflector.

A closed cycle gas turbine only has a couple low maintence parts.

PV's only serious application.

IF you can afford $.00/watt, a figure more resistant to change than
anything in the history of technology.

In sharp contrast reciprocating external heat engines like the quiet
stirling only cost a couple of CENTS/watt and are more efficient as
well.

There is no way to justify pv for serious power generation.

Fine, show me a place where I can buy a solar thermal/stirling
electric power generator for a few cents/watt in the 1 to 10 KW
range. To the best of my knowledge (which, admittedly is limited)
no such beast exists.
