Does anyone know if you can buy small personal submarines? Maybe there is a kit that I could buy to build my own small submarine. I've heard of submarines that were only the size of a person, and were powered by small motors. Any info would be great. ...
Since you need an electrical current to operate an electromagnet, where does it come from? The quick answer is that anything that produces a current can power an electromagnet. From the small AA batteries used in your TV remote to large, industrial power stations that pull electricity directly ...
The Plongeur, the first submarine to be mechanically powered, was constructed in France between 1860 and 1863. It used a reciprocating air engine fed by 23 tanks at 12.5 bars of pressure; Even though they were highly bulky, their capacity to propel the ship at 4 knots for five nautical mil...
David takes control of a Nuclear Submarine and the story is a classic one – take a bunch of people labelled poor performers and turn them around to become the top team. The interesting thing to reflect on is that David achieved this using the same technology as all other similar class su...
RN’s submarine force was particularly effective as well as the surface towed sonar arrays—perhaps the best the world had to offer at the time. Again, his appreciation of the human dimension of history weaves the story into a tapestry and not a pile of historical facts, dates and ...
For coastal trade, also might consider marine, below-the-surface trolley system using offshore wind power, and inductive transfer at the pantograph, with electric motors on the ships. Offshore wind power needs to be laced together with submarine cable anyway. As long as the cable was hung 25...
