I'm trying to figure out what is the maximum possible amount of watts that you can squeeze into a $m^2$ by concentrating sunlight.
This similar answer explains how 42600x is the maximum amount we can concentrate sunlight. And $1000 W/m^2$ is the average intensity of sunlight you can assume on most days.
Does that mean that $42600000 W/m^2$, which results from multiplying the two above numbers, is the maximum intensity concentrated sunlight can achieve?
As a follow up question, how close to achieving this are we in real life? What is the solar intensity currently reached by some of the solar furnaces, like the Odeillo solar furnace in France?
