Why study history, and such an ugly subject as the Nazi rise in the Weimar Republic? Because quoting George Santayana, those who cannot remember the past are condemned to repeat it. It seems we have forgotten a lot, because, as a civilization, we are repeating the mad Nazi schemes of renewable energy on a massive scale.
A good source document is this book:
Cover of Technology and Economy in Third Reich: A Program for Work by Franz Lawaszeck, published in 1933
Dr. Franz Lawaszeck was an inventor and manufacturer of hydropower turbines in Bavaria. As an early member of Nationalsozialistische Deutsche Arbeiterpartei (the National Socialist German Workers’ Party or Nazi Party), he soon became a prominent spokesman about the economic policy of the party, especially energy policy.
