A better argument for steel is it requires 5-10 kwhr/kg to produce vs 60kwhr/kg for aluminum and 250kwhr/kg for titanium. So for the same energy you get 6 times more steel than aluminum and 25 times more than titanium. Which seems to say when the properties of steel are acceptable it's the cheaper option. https://solar.lowtechmagazine.com/2009/06/how-much-energy-do... |
