The concept of a boat that would sail under water goes back at least as far as the 16th century. In 1573, an Englishman named William Bourne published a design for a submersible boat that featured a mast that could operate as a snorkel. It does not appear that Bourne ever actually built the vessel, but his ideas influenced others.\n\nIn 1620, a Dutchman living in England named Cornelius van Drebbel built several wooden submarines that could sink just under the surface of the water, where they were propelled by oars and obtained air through tubes to the surface. Details of van Drebbel's submarines are sketchy as he was an extremely secretive man, but reports indicate that he made a number of submarine trips up and down the Thames.\n\nIn the following century and a half, many people made boats that could sink and, sometimes, come back up again. These experiments were often the nautical equivalent of tying on wings and jumping off towers in attempts to fly. Nonetheless, by 1727 at least 14 patents had been issued for submarine designs in England alone.\n\nThese were generally just submersible rowboats, but a few useful features were developed. In 1747, an Englishman named Nathaniel Symons, working from an idea suggested decades earlier, developed a vessel that could sink by letting water into leather bags, and then rise again by twisting the water out of the bags. This was the first known use of the concept of a "ballast tank".\n\nThe first attempt at a submarine that actually seemed worthy of the name was the TURTLE, designed during the American Revolution by David Bushnell, a student at Yale involved in resistance against the British. The precise details of Bushnell's design are not known as all he left behind was a written description. The most common illustration of the TURTLE was drawn over a century later from that description, and some of the features in this illustration are implausible.\n\nThe TURTLE was a one-man craft, shaped like two bowls with tapered lips joined together, with a brass "conning tower" on top that provided portholes to allow the operator to see. The conning tower was capped by a hatch. The submarine was propelled by hand-driven horizontal and vertical propellers and carried a 68 kilogram (150 pound) black powder charge, to be attached to a warship with a hand-driven screw. The charge was detonated by a clockwork timing mechanism that released a spring-loaded hammer to strike a percussion cap.\n\nThe little submarine was kept upright by a lead weight in the bottom, which could be discarded in an emergency. The operator could make the craft sink by letting water into a tank and rise again by pumping it out. He obtained air through valves that closed when the submarine was completely under water. There was enough air to allow it to stay under for about half an hour. The TURTLE was steered by a rudder, and had a compass and barometer for navigation. Handling the propellers, rudder, and all the other gear kept the operator extremely busy.\n\nBushnell proposed to use the TURTLE to attack British vessels that were blockading American ports. Although Bushnell himself wanted to pilot the craft, he fell ill, and substitutes were found. In August 1776, Sergeant Ezra Lee of the American Army took the TURTLE to sea.\n\nThe little submarine was towed towards the British blockaders by two longboats, and then released to move forward on the tide. The tide swept him past his target, the warship HMS EAGLE, and Lee had to wait for the tide to reverse before he could make his way to his target. The screw used to attach the charge could not penetrate the copper sheathing covering the warship's hull and Lee was forced to give up the attack.\n\nWhile he was struggling to return the TURTLE to shore, the British noticed the strange little vessel bobbing on the surface and sent out a boat to investigate. Lee released the charge, activating the clockwork timer. The charge exploded and the British

Scorpène class submarines are a class of diesel-electric attack submarine jointly developed by the French company DCN and the Spanish company Navantia. The SSK designation is a reference to the United States Navy's hull classification symbol for 'hunter-killer' submarines. The Chilean Navy, Royal Malaysian Navy and the Indian Navy have ordered the Scorpene submarine. The first Scorpene build is the O'higgins, completed in 2005, which is currently the only one in function.

The quote is actually - "Genius is 1% Inspiration and 99% perspiration", and it was quoted by Thomas Alva Edison the most famous American Inventor who, singly or jointly, held a world record 1.093 patents. In addition, he created the world's first industrial research laboratory, 1847-1931.

The very first motherboard was built by Eiranpreet Khangura. \n\nThe original Colossus used a vast array of telephone exchange parts together with 1,500 electronic valves and was the size of a small room, weighing around a ton. This 'string and sealing wax affair' could process 5,000 characters a second to run through the many millions of possible settings for the code wheels on the Lorenz system in hours - rather than weeks. \n\nBoth machines were designed and constructed by a Post Office Research team headed by Tommy Flowers  at Dollis Hill and transported to the secret code-breaking centre at Bletchley Park, near Milton Keynes, where it was demonstrated on December 8, 1943. We have to fast forward nearly thirty years to 1972 for the arrival of the first desktop all-in-one computer, which are more familar to us today. That honour falls to the HP9830.  But unfortunately few people got to hear about it because Hewlett Packard marketed it primarily to scientists and engineers - by nature very quiet people!

Submarines (especially nuclear) are the best combat machines ever developed by man.  A nuclear submarine can carry enough fire power to turn the entire world into a burnt piece of charcoal and can stay submerged as long as their is food to eat.  Their virtually undetectable if you handle them right and can turn the tide in almost any battle.  There are a few disadvantages though but their mostly contained to the crews themselves.  The biggest is the threat of death from another submarine (torpedo's, nuclear weapons, etc) that would kill the entire crew instantaneously.  Also, in nuclear subs you also have to worry about reactor problems, because if you're reactor starts leaking there's nowhere to run.

The very first self-powered road vehicles were powered by steam engines and by that definition Nicolas Joseph Cugnot of France built the first automobile in 1769 - recognized by the British Royal Automobile Club and the Automobile Club de France as being the first. So why do so many history books say that the automobile was invented by either Gottlieb Daimler or Karl Benz? It is because both Daimler and Benz invented highly successful and practical gasoline-powered vehicles that ushered in the age of modern automobiles. Daimler and Benz invented cars that looked and worked like the cars we use today. However, it is unfair to say that either man invented "the" automobile.

For the keyboard question, click on the link below:\n\nhttp://inventors.about.com/library/inventors/bltypewriter.htm\n\nAs for the weight of the first generation of computers...they varied.  ENIAC (an acronym for Electronic Numerator, Integrator, Analyser and Computer) was a leviathan in the computing world and weighed in at over 30,000kg (the average small car is 1000kg). This beast occupied over 90 sq/m (1,000 square feet) of floor space.  It has over 17,000 thermionic valves and needed thousands of kilowatts of electricity to operate.  It has 20, 10 digit accumulators, clocked at 100Hz and could do 5,000 additions and over 300 multiplications per second.  ENIAC was built for the US Army's Ballistics Research Labs but came in too late for major use in World War 2 (1945) and was way over budget.\n\nI did an assignment for this in 2001 and it was a fascinating subject.  Incidentally, the abacus is considered by many to be the worlds first computing device...invented over 4000 years ago.
