"Nordenfelt-submarines" Topic

"The Nordenfelt submarines of the 1880s are an underappreciated part of submarine history. They were midway between the human powered submarines of the American Civil War and the gasoline and diesel boats of the 1900s. So much of their technology was ground (sea) breaking. Yet they are generally not seen as a service-ready proposition (this could be challenged). So maybe they were too bold, too soon. But while it is true that the technology of the day limited their service, they are an important part of the submarine timeline.

The submarines were designed by British inventor Reverend George Garrett. He had already built a steam powered submarine, the Resurgam, in 1879. Key to the underwater propulsion was that steam from the normal surface running was stored in large tanks. This was then released slowly to power the steam engine after the boat submerged. In theory it was an impressively simple concept and used technology available at the time. In practice the interior of the extremely small submarine was almost intolerable. Unfortunately the submarine sunk under tow before it could be tested by the Royal Navy…"

I would agrue a bit with the intial idea. They are a progression of the David class steam torpedo boat of the American Civil war rather than the hand cranked submarine.
