This Swedish Inventor OUTSMARTED Detroit With a Weird Free Piston Engine in 1928

What if the most efficient engine ever built was deliberately buried by Detroit because it threatened their entire industry? In this video, we explore the incredible story of Birger Ljungström's revolutionary free-piston engine from 1928 - a Swedish invention that achieved double the efficiency of conventional engines while using 80% fewer parts. Discover how this radical design with no crankshaft or connecting rods terrified American automakers, why Detroit's engineering establishment dismissed it as "Swedish nonsense," and how modern companies like Toyota and Tesla engineers are now revisiting this century-old technology that was simply too far ahead of its time. #engineering #automotive #history #innovation #technology
