Submarine

Belgian diving enthusiast and inventor Rene Baldewijns found that dive boats were rarely available when or where he wanted to dive and that a lot of dive time was lost looking for the area he wanted to dive in. So he conceived a boat that that could drive itself off the trailer, along the road and into the water whilst carrying larger quantities of air and equipment than any diver could carry. His dream boat could travel to the dive area like a speedboat and then literally ... pull the plug out and dive. Whilst dived, it had to be able to cruise around underwater until he found the right area, then park on the bottom as an underwater base to support diving activities for two. When finished, the idea was to blow the ballast, surface, and return to land at high speed, driving out of the water and onto its trailer. The prototype he built has achieved all those aims.  Read More

November 7, 2004 While fuel cell automobiles promise reduced emissions on land, the high seas have long enjoyed a virtual amnesty from air emission regulations. There is no effective way to regulate pollution emmissions from ships, yet the fuel cell has a bright future under the water as the best alternative to nuclear energy. The fuel cell has many advantages for submarines, the most compelling being that of completely silent running. A fuel cell submarine such as the new 212 and 214 from HDW can lurk beneath the waves invisibly for three weeks at a time. Unlike other non-nuclear submarine variants such as gas turbine and diesel engines, fuel cells can also be distributed throughout a ship for increased design flexibility, which in turn reduces shipbuilding costs. The company that makes this new monster also made the world's first wartime submarine, and is now offering retrofits.  Read More

Swedish designer Milko Ozlu has always been intrigued by the concept of the powered exoskeleton and body amplifiers. When the US Military experimented with the springwalker concept in the late 1980s, Ozlu was fascinated, though it was long before he studied for his BA in industrial design at Konstfack in Stockholm. His ideas followed through and when he was studying for his masters degree at the vehicle design department of the world-renowned Royal College of Art in London, it resulted in one of the most interesting degree projects we’ve seen – the U-Scull, a new type of human powered sports-submarine that operates in shallow depths.  Read More

The world's first practical submarine was built in 1620 by Dutch engineer Cornelis Jacobszoon Drebbel, under the patronage of James 1 of England. Drebbel built three submarines according to the sketchy information available from that time, each larger than the last and the third being capable of carrying 16 people, of which 12 were the oarsmen. The oarsmen rowed one oar each, with the oars protruding from the side of the boat through waterproofed leather seals. Air was supplied by snorkel-like tubes that were held above the water's surface by floatation devices, enabling the submarine to be underwater for long periods. Accounts suggest the boat could travel from Westminster to Greewich and back under water, completing the return journey in three hours at a depth around 15 feet below the surface.  Read More

Deep Flight is a radical new design approach to underwater vehicles that uses wings instead of a traditional ballast system to "fly" through the ocean depths.  Read More
