It looks like a small, enclosed speed boat, with two clear bubbles on top for the operator and passenger to behold the wonders of the deep. The CQ-2 twin seater personal sub, manufactured by C-Quester, is a fully electric mini-sub that's capable of maintaining cabin pressure at one atmosphere. The same inventors came up with the idea of the torpedo at the same time, making the new submarine a very unique war tool. These subs were powered by petroleum or steam on the water's surface and used electric motors under water. Two rival inventors developed these two designs, which were purchased by the militaries of the United States, Russia and Japan. Skip ahead again to the 1890s, when the first modern-style subs were built. The United States military used The Turtle during the Revolutionary War, to middling success. The first military sub, The Turtle, was built in 1776 by David Bushnell and was powered by hand-cranked propellers. Of course, there were no engines at this point, so Drebbel and his 12 oarsmen hit the Thames River and submerged for about three hours. ![]() Fast forward about 50 years when a Dutch inventor named Cornelius van Drebbel built the first working submarine. He's basically saying that if you make the boat heavier than the weight of the displaced water, it will sink (purposely). It may be 1570s English, but the concept was undoubtedly that of a submarine. Any magnitude of body that is in the water, having always but one weight, may be made bigger or lesser, then it shall swimme when you would, and sink when you list." "It is possible to make a Ship or Boate that may goe under the water unto the bottome, and so to come up again at your pleasure.
