Aluminum

Added: Jun 2nd, 2008
is an energy investment in the future. Someone once said it is solid electricity. I think it's petroleum/coal solidified. It takes incredible amounts of energy, especially electrical to produce this wondrous metal. Once that initial investment is made, it requires very little energy to make it change form. Aluminum is an energy investment, and is already paid for. Our trash piles are full of it. It will melt for casting at around 1400 degrees. Local solar furnaces might provide enough energy to smelt that aluminum, and with simple sand-casting can be made into usable tools and products. Good local business opportunities. It's time to figure out what we need, how to build it, and how to make the tools to build the future. No big deal, right? Put your creative mind to work.... Also, pot metal (some kind of zinc compound) is another fine feedstock. It melts at even a lower temperature than aluminum, and in some cases is stronger. Put your thinking cap on and be in touch...we have the materials and the knowledge to retool our world. We just need the will.
