A Very Detailed Expose’ Of Solar Power.

This article details the problems with efficiency, scale, materials and cost, but the main problem is storing the energy when the sun don’t shine. Attempts to do so just reduce the already highly expensive and highly inefficient power to the ridiculous level.
Keep inventing guys!

” …Troughs are oriented north to south so that a servo can rotate them to follow the sun during the day. The efficiency of the system is the product of the optical efficiency (percent of incident sunlight captured) times the thermal efficiency (percent of solar radiation absorbed by the receiving tube), times the thermodynamic efficiency of the Rankine cycle generator. Howard Hayden in his book The Solar Fraud estimates these as 71 to 80 percent, 35 to 50 percent, and 35 percent respectively. Thus the efficiency of producing electricity from solar energy is approximately 10 percent.

The peak insolation (solar energy striking a surface — in this case, Earth) used for calculating peak power outputs from solar power is considered to be 1,000 watts per square meter. (This number represents a theoretical insolation; it cannot actually be found on Earth.) From this we see it takes about 1,000 square meters (10,000 square feet) of mirrors to produce one megawatt of electrical energy. A 100 MW solar power plant (one-tenth the capacity of a typical nuclear plant) using mirrors that are 10-feet “tall” would then require 100,000 linear feet of parabolic trough — just shy of 19 miles…. “

  1. Hi Grant,
    I really feel sorry for all the ordinary working people that will end up paying for this crap. 😦
