The problem with Venus receiving direct sun light is that it has an incredible thick atmosphere so that sunlight that hits Venuses surface is reflected from a height of 45mi so the sunlight received by Venus at the surface is essentially zero.

My book says that Venus semimajor axis is 0.7233 AU. This gives an average "radiation dose" of 1.911 times what earth gets (Inverse square law). But you say ON Venus. Venus albedo is 0.65 which means, on average, 65% of that incoming sunlight is reflected off by the Venusian cloudcover. And so only 35% of the light gets through. So the Venusian surface actually gets less sunlight than earths surface does...

The inverse square law is expressed like this:
L=1/(d^2)
L is luminosity and d is the distance.

My book says Venus is 0.723 of the Earth's distance to the Sun. Using the inverse square law (1/0.723)^2 = 1.91.
91% more than Earth.

0.123834 because the clouds on venus are only open for 1.643 minutes every day. Then the clouds close up and trap the heat.
