$this->bbcode_second_pass_quote('smallpoxgirl', 'M')y question is....how the heck do you forge a 300 ton crankshaft out of a single piece of metal?
Does a crankshaft have to be forged or could have it been casted?
Because casted metal is melted down, the chemical bonds that hold the atoms together get weaken, but on the plus side casting metal is a much cheaper way to manufacture something compared to forging.
Getting back closer on topic why is it that so many greenies have such a disdain for large machines? They seem to have this glorified image of "localization" as if the "smaller is better" attitude. For example:
home gardening ...................... factory farming
small shop ............................. walmart big box store
small windmill .......................... a 400 feet high one
I guess greenies must not care for the benefits of "economies of scale". I believe that one of the greatest contributors to the increase in quality of life for humanity was taking advantage of "economies of scale".
