Here’s what you are proposing with a greenhouse effect limited by the temperature of the sun’s photosphere.
We (meaning an engineer like me) could take a very well insulated box black on the inside execept for one side where we’d put a one-way mirror. This is the ultimate greenhouse. If the maximum internal temperature was limited only by the photosphere’s temperature we could get the inside of that box hot enough to generate high quality dry steam to run a turbine which is a mere 500C not the 5500C of the photosphere.
It simply can’t be done. In order to heat things that hot in the real world (as opposed to your fevered imagination) we have to use lenses and/or mirrors to concentrate the energy which by necessity deprives some other surface from that amount of energy.
Do you have any idea whatsoever how f***ing much of a laughingstock you are for proposing something physically impossible?
