6. The intensity of sunlight striking the earth is 1.4 kW/m^2. What is the maximum power that could possibly be absorbed by the earth? (The earth's radius is 4000 miles). How does this compare with the power demands of humankind? Given that the earth-sun distance is 93 million miles, and the pluto-sun distance is 4 billion miles, what is the intensity of sunlight striking pluto?
