re: DUH, get a scientiufic education
"The disk is PI * R^2. the sphere is 4 PI * R^2, so the sunlight, on average, is only 1/4 as strong when you include night, winter, lattitude...
So our nominal 1360 W/sq m becomes 340 W/sq m, averaged over time and space."
You also have clouds, so therefore, somewhere around 250 W/sq m
"The heat flow is an average as well. Apples and Apples..."
Suppose you had a planet in which the geothermal heat instead earth's .05 watts per sq meter, was 200 watts per sq meter. How would you characterize that planet?
Are there places on the surface of earth in which one has local geothermal heat of say 200 watts or higher per sq meter?
If a recently cooled lava flow can be walked on, how much heat per sq meter is generally being radiated?
