The Goubet I submarine was a two person, electric submarine built by French inventor Claude Goubet in 1885. Manufactured in Paris, the sub has gone down in history as the first to be electrically powered, with a brace of cutting-edge tech advancing more primitive models. The Goubet I was battery powered, utilized a Siemens electric motor to drive its propeller and power a navigation light, and measured 16.4 feet long. The craft weighed in at just over six tons. It was controlled from a central position, with its two crew positioned back to back, seeing out of the vessel via small glass windows; they could see up, down and to the sides to some extent thanks to prisms. After testing in the River Seine in Paris, however, the Goubet I was ultimately deemed a failure, because the submersible wasn't able to maintain a stable course or depth while moving forward. As a result, while some of its innovative technology lived on in later designs, the Goubet I itself was quickly scrapped.
