Re: Energy Density of Coal Fired Power Plant

A 450 megawatt plant including coal and maintenance sheds and yard will
take up most of a square mile or 250 watts/m^2.

You can do better that with dish stirling.

Your subject line is about energy density, why are you talking in units of
power/area?

To make sure you were awake reading these educational threads.

How much *energy* does that 450 MW plant generate in an average year, versus
how much energy does the dish Stirling? I think that is the more pertenent
question.

Once you factor in the height and width of the steam plant -- true
power density --, then dish Stirling _really_ looks better.
