Technology in the World of Avatar

Technology in the Avatar World varies largely from the industrialised Fire Nation to the pre-industrial Air Nomads and Water Tribe.

Air Nomads
The Air Nomads never industrialised, due to their insistence on making the least amount of environmental impact on the world as possible. The Air Nomads did however have enough technical knowledge to produce their gliders.

Examples of Technology

 * Glider - Support tool that Airbenders have frequently used for assistance in Airbending.
 * Air Temple Sanctuary Door - The door is opened only using Airbending.

Water Tribe
The Water Tribe has limited technology.

Examples of Technology

 * 'Stink and Sink' - Aquatic bomb invented by Hakoda.

Earth Kingdom
The Earth Kingdom has limited industry and has some technological advances.

Examples of Technology

 * Omashu Mail Delivery System - The Omashu mail system is just a linking slide that goes on for miles in the city. Earthbenders move the packages around to a different slide.
 * Ba Sing Se Monorail - Enormous train network stretching across the whole of Ba Sing Se, connecting all three Rings. It serves as its mass transit system. The monorail is pushed from one end of the rail network to the other by a group of elite Earthbenders.
 * Sand-sailors - these are gliders, used by the sandbenders to travel trough the Si Wong Desert

The Mechanist
The Mechanist is a prolific technological innovator. He belonged to Earth Kingdom and had settled in Northern Air Temple he made weapons for the Fire Nation to save the other refugees with him. Aang finds this out and gets angry but helps them fight Fire Nation but his invention Hot Air Balloon was found at end of episode of The Northern Air Temple and they use it in war as a mighty weapon and this is seen in the episodes of The Day of Black Sun, Part 2: The Eclipse and Sozin's Comet, Part 3: Into The Inferno.

Inventions

 * Hot Air Balloon - Experimental weapon developed for the Fire Nation.
 * Waterbending Powered Submarines - Naval vehicles used in the Invasion of the Fire Nation.
 * Earthbending Powered Tank - Vehicles owned and operated by the Earth Kingdom Military. Used in the Day of Black Sun.
 * Earth Kingdom Supply Truck - Motorized, metallic vehicles. They were supposedly designed by Sokka in preparation for the invasion. They were used as a means of cargo transportation.
 * Ice Torpedo - Weapon designed for use in the invasion of the Fire Nation.
 * Peanut Sauce Bombs - Explosive weapons.
 * Timing Device - Form to keep track of time during an eclipse.
 * Time Candles - Candles used to see the time.
 * Cut-Safe Knife Sharpener -

Fire Nation
The Fire Nation is the most technologically advanced nation in the world.

Examples of Technology

 * Tank Train - It is a Fire Nation engineering marvel. It is a cross between a tank and a train.
 * Fire Nation Drill - It was a very large, hydraulic metal drill which was designed to penetrate the "impenetrable" walls of Ba Sing Se, so that the Fire Nation could conquer the Earth Kingdom capital and ultimately win the War.
 * Fire Nation Tank - Tanks are large armored vehicles.
 * Fire Nation Trebuchet - These catapults are used to conduct long-range warfare, and have appeared to come in different sizes from being huge fixed catapults on Fire Nation ships.
 * Fire Nation Airship - It is a massive aerial vehicle.
 * Jet Ski - Another vehicle in the Fire Nation's war arsenal, these steam-powered jet skis are perfect for short-range water travel and warfare.
 * Fireworks - Explosive pyrotechnic device used primarily for aesthetic and entertainment purposes. Used in the Fire Days Festival.
