I don't really know what you're after Seden. The main driver of the climate from a purely physics perspective is the absorption of heat by the various greenhouse gases in the atmosphere. Without them the earth would be too cold to support life. As you may be aware I don't subscribe to any outlandish theories that try and discount this significant effect and place it with cosmic rays or angular momentum or friction or whatever.
Like Dogby, I've also got a pipe dream on my roof and it is generating energy like it is going out of fashion on a sunny day in Melbourne today!
