Why not try using aluminum for building bridges? Aluminum is really very strong!!

Maybe the reasoning is that we are not producing enough aluminum nor even consuming enough aluminum to warrant more aluminum growth. We are more interested in pointing fingers at aluminum as too intensive in electricity for production without any after thoughts about the far less energy required to recycle and cast aluminum. Steel requires the same energy to produce new as recycled while aluminum is only 7% of the energy required to produce new. We need to put far more aluminum on the table for future recycling that can power economic growth.

We can use aluminum in concentrated solar power that can be used to power additional new aluminum production while we cannot with steel. We appear not to desire solutions as we seem to desire miseries. More of them…
