Only nuclear-powered boats generate steam for propulsion, electrical, and potable water conversion. The heat from the reactor flashes water into steam; the pressurized steam is then channeled toward a set of turbine generators, which provide electricity and are also connected to main engines for propulsion. Sea water is also desalinated using the the steam (condensed for various crew/boat uses) and stored as potable water for drinking/bathing, or de-ionized water for making oxygen.

When did Robert Fulton create the steam boat and submarine?
100 bc
Who invented steam boats and when?
Robert Fulton invented the steam boat in 1800. He was a colonial American Engineer. He designed the first submarine of the world called "Nautilus".
What was the problem of steam driven torpedoes in World War 2 submarine warfare?
Steam powered submarine torpedoes had a flaw when a submarine fired torpedoes in daylight. The torpedoes created a massive stream of bubbles that rose to the surface of the ocean and enemy ships could see that they were under attack. The bubble stream also gave away a submarine's position. This problem was solved for the Germans when they developed electric torpedoes. No bubbles were produced. The US Navy captured some of the enemy torpedoes and used them for models of their own new electric torpedoes.
Robert fulton inventions?
Robert Fulton's inventions include the steamboat, steam engine and submarine, among other things.
How is steam used to power a nuclear submarine?
Steam from the nuclear reactor turns turbines. These turbines either turn the propeller directly or turn generators that produce electricity to power electric motors which turn the propellor.
Do nuclear submarines generate nuclear power on the submarine?
Yes, nuclear submarines generate nuclear power. There is a nuclear reactor on board (hence the tern nuclear submarine) which creates steam to drive the main engines to turn the screw(s).
Why can nuclear powered submarine stay submerged for months at a time?
The key to the range and duration of the modern nuclear submarine is the nuclear reactor. The reactor generates heat through nuclear fission, and this does not use air (or the oxygen in it). The heat is used to make steam, and the steam drives conventional steam turbines. With a large power source and no requirement to be on the surface, the boats can stay down for an extended period limited only by the amount of provisions they can stow aboard prior to deployment.
How does a diesel submarine recharge its batteries?
World War II submarines were powered by large electric motors. On the surface, the motors drew their power from diesel generators, not unlike how a diesel locomotive operates today. When submerged, the diesel engines could not be operated, and the motors drew their power from huge banks of electric batteries. After the batteries were drained of their power, the submarine would have to surface in order to run its diesel generators to provide propulsion and electric power to the submarine. During this period, the sub's batteries were recharged. Toward the end of World War II the submarine snorkel was invented, which gave a submarine the capability of running its diesel engines while submerged. The submarine was required to stay relatively close to the surface, but it was fully submerged with the exception of the snorkel mast. Nuclear powered submarines also have banks of electric batteries, but they are only used when the main propulsion plant and/or its steam-powered electric generators are disabled. When a nuclear-powered submarine's batteries are fully drained, they are recharged by the boat's diesel generator if its steam-powered electric generators are not available, or by the steam-powered electric generators when they becomes available. Just like a diesel-electric submarine, a nuclear-powered submarine must operate its diesel generator on or near the ocean's surface.

What were the names of the submarines in the Civil War?
The South had a submarine called the Pioneer which was renamed the Hunley and operated by the Confederate Army. It became the first submarine to sink an enemy vessel in war, but it was also sunk. The North had a submarine called the Intelligent Whale which was not used in the war. The South also had steam-propelled craft called Davids which may or may not be considered submarines because they were not capable of submerging fully.
What kind of engine does a submarine use?
They typically run on steam power, using nuclear reactors to create the steam. Prior to the development of the nuclear power systems, they used electric motors through batteries, that were charged using diesel engines. On the surface the diesel also propelled the shafts.
Was there ever a steam powered submarine?
The answer is yes, but it might not be what you think. The early application of steam power to do work saw its use in a wide variety of vehicles, both on land (cars, trains, etc.) and on water (steamships). Steam generation requires a heat source, and in all the early applications of steam, some form of combustion was employed to boil the water. We had to burn something. That meant using air, or at least the oxygen in it. The submarine, which had long been dreamed about, had crept along in its development. But it always used human power (or springs or something else quirky) to drive it under water. Some early attempts were made at employing electric motors with batteries, and later on that finally became the key to building a "real" u-boat. Designers added an internal combustion motor that drove a generator, and they also added a big bank of batteries. The "modern" submarine began service. These submarines had to surface to charge batteries, but could run quite a few hours submerged. They had limitations, but were an extraordinarily effective weapon in World War II. (There are a lot of articles about that.) World War 2 ended on a note that saw the entrance of applied atomic energy. The use of a nuclear reactor as a heat source for powering a submarine, which had already been envisioned, was realized by designers and engineers, and then built. The submarine was given a nuclear reactor, the primary useful product of which is heat, and the heat was used to generate steam. No air is required in that process. Almost all of the new military submarines have a nuclear reactor, and it is used as a heat source. But they have "conventional" steam plants with steam driven turbines that power up the propeller (called a screw) and steam turbine generators that make electricity.
