Immersion heaters are used for heating water in a hot water tank. Immersion heaters are usually controlled by thermostat and they will heat your water to a set temperature for as long as you leave it on that setting, or you can have a timer set. It is usually an expensive way to heat water compared to central heating systems with hot water circuits.
A high-quality microscope objective lens with a specialized coating is typically used for oil immersion microscopy. The lens is designed to work with a specific type of oil (usually immersion oil) to enhance resolution and numerical aperture by reducing light loss due to refraction. Oil immersion microscopy is commonly used for high-magnification studies requiring precise imaging, such as in medical or biological research.
Oil immersion is used to minimize light refraction and increase resolution by eliminating the air gap between the lens and the specimen. The oil has a refractive index close to that of glass, allowing more light to enter the lens and improving the quality of the image.
Immersion oil is used in Gram staining to enhance the resolution of the microscopic image. It helps to reduce the refraction of light, resulting in a clearer and sharper image of the bacterial cells. This is particularly useful when observing Gram-stained slides under oil immersion microscopy.
When using the oil immersion objective, the oil has the same refractive index as the glass. So it is like an extension of the lens. Water does not have the same refraction index as glass, so the image would not be as clear.
Cedar wood is used with oil immersion objectives in microscopy because it has a refractive index similar to that of the oil (usually 1.515) used to fill the space between the objective lens and the specimen. This minimizes light scattering and improves image quality by increasing numerical aperture and resolving power.

Heat can be wasted in immersion heaters through poor insulation, inefficient design, improper sizing for the application, or by leaving the heater on when not needed. To minimize heat waste, it is important to use properly insulated immersion heaters, select the right size for the specific heating requirements, and only operate them when necessary.
I would suggest look at chromolax and omega. Another good place to look would be Home Depot. Prothermind also offers a complete line of immersion heaters.
Immersion heaters allow you to heat liquids directly. This is more efficient than heating the object that holds the liquid, because the heat must heat the container, then the container must heat the liquid. Other heaters cannot do this because they cannot be submerged into liquids.
Immersion heaters are electric devices that heat water or other liquids when they are immersed in the liquid. They have several uses that range from domestic to industrial. You may recognize an immersion heater as the heater that you place in your fish tank to keep the water temperature regulated. Screw Plug Heaters Screw plug immersion heaters are short tubes placed in a hexagonal plug that is threaded. They are designed specifically to fit into holes that are built in the sides of tanks that hold water or pressurized gases. The screw plug heater creates an air-tight seal when it is screwed completely into the tank. A small gauge on the head of the heater will give you the readings as the temperature inside the tank changes. Even a small immersion heater can change the temperature of a large volume of water or gas when it is contained in a sealed tank. Screw plug immersion heaters are primarily used in industrial settings. Side Mounted Heaters If you need to heat a large volume of water or other liquid but you don’t have the luxury of penetrating the side of the container, side mounted immersion heaters may be the right choice. The heating element is a long tube that is extended from the end of a vertical bar. An attachment at the top of the vertical bar will allow you to hang the heater into the liquid from the side of the container. These immersion heaters are far more flexible than other types, and can be moved from tank to tank or removed for cleaning very easily. Flanged Heaters Flanged immersion heaters create a high level of heat very quickly. They consist of several heating elements bent into a tube shape and welded onto a flange. The flange is inserted into the side of the tank that holds the substance that needs to be heated. Flanged immersion heaters are ideal for creating steam, because they heat liquid substances to very high temperatures quickly enough to cause vaporization. You can buy flanged heaters with several different sizes of flanges to fit your particular application. Flanged heaters are used for several industrial purposes.
Assuming you're taking about 'twin core and earth' cable - it's commonly used to supply power to high-current devices such as cookers and immersion heaters.
Yes, there are immersions heaters for vehicles and travel. They are typically used for camping though. I'd be careful using one while driving. http://www.amazon.com/Travel-Immersion-Water-Heater-Voltage/dp/B000AXS0UE
you could insulate around the immersion :)
Used oil heaters can be purchased from Central Ohio Heaters, Northern Tool, Lanair, Yakaz For Sale, Firelake Manufacturing, Kutrie Waste Oil Heaters, Oil Burners, and Clean Burn.
Corona kerosene heaters are used for heating up a stove and acting as small lanterns or heaters. They could potentially be used in cases where your normal heater is burned out.
It is unlikley that you couldconfigure many airconditioners to be used as heaters.
