Speaking of great inventors, great inventions, steam, and things that will never work—stumbled upon this yesterday:
Lincoln’s Secret Weapon:

Ironclad warship, steam powered, screw propeller, rotating turret, powerful naval guns. Of course, all of it was highly dangerous and none of it caught on. Impractical. The inventor was even banned from doing business with the government for a period after a gun exploded during a demo.
This one has commercials. That’s scary.
An early example of government interference.
