I did take a look at that link and was hoping for a response from someone more knowledgeable than I.
My chosen area of study is Architecture rather than Engineering, but what I can tell you is the refining of aluminium uses vast amounts of energy compared to any other metal. It is in the order of multiples of that required for steel. I have heard the nick name used 'solid electricity'. Unfortunately your propostion the metal is 'green' because is uses hydro is not a full appraisal. Firstly it doesn't consider the damage a dam does to the ecosystem. Second the process leaves toxic by products, including fluorides. I have worked at the Aluminium Smelter in Tiwai Point, New Zealand. The toxic waste there is buried just back from a pristine beach. Environmental laws have gradually seen them reduce the stack emissions, and that was the project I was working on. However I heard stories of livestock downstream from the stack suffering from birth abnormalities. I am sure working in that environment contributed to the cancer I suffered 10 years ago. I would love to hear any counter argument for the Cornish Generator though.
