"I am an engineer. I've spent a life time in electronics and optics. I am thoroughly familiar with the technology and the economics of solar power."

You couldn't tell it from your vanity post. You aren't just comparing apples and oranges--you are comparing mustard seeds and watermelons. There "are" a few different sorts of solar cells, with widely differing efficiencies and costs. Hell, you don't even give the BASELINE PARAMETERS for your assumptions. Add to that the "strawman arguments" about hailstorm damage (the answer to that particular one is called "polycarbonate").

Get your mouth and attitude under control.

I thought you were the bandleader for the hydrogen parade; what is it, photons or protons?
