I understand that. But a 1500 to 1 expansion you can extract some
real power from that energy.

With a 3m diameter mirror it's possible to get over 1000C of
sunlight concentrated into a relatively small spot. It is possible
to create enough steam to drive a TC from it? What if we preheated
the inlet water?

The energy is cheap. The question is can we gather enough of it
to generate enough steam to drive a TC?
