In the days of Queen Victoria they said, truthfully "the sun never sets on the British Empire". But it does set on Australia, every single day. Even the green power engineers in Parliament must have noticed that the sun also sets on all those solar panels that their mandates and subsidies have plastered onto Australian roofs. Solar energy is most intense on the equator but weakens towards the poles. It disappears when the sun sets or cloud obscures the sun. For just six hours or so per day during summer, in a clear tropical desert area, solar energy is reasonably reliable and collectible, although always very dilute. But at times of peak demand, about 6.30pm in winter, solar panels contribute nothing to electricity supply. Billions have been spent on researching ways to store massive amounts of solar energy to cover the eighteen hours per day of low or zero solar supply. Many things will work in the lab, even a big bank of car batteries. But once real engineers take over from...(Read Full Post)
