Now you spent umpteen billions on a shiny new Steel Wall of PowerTM
Now what? The wall runs over hill, over dale, between water and forestdesert.
Now? you maintain it. This isn’t cheap. The Golden Gate Bridge, pictured above costs $65 million dollars a year to maintain. It is 1.7 miles long. Nobody would think a wall would take the same maintenance as a bridge, but…Steel is strong, but doesn’t last without help. Help isn’t cheap. Are we talking Billions a year? No, we’re not talking about any...
