Technology

Technology in the Other World is a mix of technical, physical and magical aspects.

But since there haven't been much development in the technical aspects of technology, many of the system rely on primitive or improper methods, like large Ships being hauled by large tamed beasts, tamed Wyverns carrying Gondola, or lack of knowledge on pathogens resulting in improper usage of Healing Magic, etc.

Also many of the currently used technological items are from the Lost Ancient Civilization (these items are commonly referred as "Artifacts"), and information on them are scare and missing, so the main purpose for those technology is unknown, but different uses for them have been discovered.

Unnamed Aptitude Testing Device
This unnamed device is commonly used to verify the type and element of Magic a person can use. The device supposedly looks like a 'stone slate' in the Novel, while in the Anime it looks like small gargoyle stone statue on a pedestal. And when a person touches it, it projects the type of magic and its abilities in the mind of that person.

No one currently knows the principle and mechanic on how the 'stone slate' works, mainly because its an artifact from lost ancient magic technology.

Ships
In the world of Landia, steel ships are not propelled by internal combustion engines, but are pulled by giant Sea Dragons. Basically, steel ships are sea-going carriages.

Battleship Albert
Main Article: Battleship Albert The battleship Albert was the only commissioned steel ship of Elfrieden's Navy during the time of Kazuya Souma's summoning. Like all other steel ships, it was pulled through the sea by giant Sea Dragons. it was described as having two, large, dual cannons fore and aft as well as several, smaller secondary batteries. The armaments are not fixed and were removed to make more room for cargo. During the One Week War, Kazuya used the battleship as a makeshift railway gun, by putting it on rollers and having 3 Rhinosaurus haul it on land. To defend against air attack by wyverns, anti-air ballastae were installed.

Carrier Hiryuu
Main Article: Carrier Hiryuu

The Hiryuu is the first aircraft carrier of Landia, which means it carries its own air power, (wyverns), at sea. It is also the first steel ship that does not rely on Sea Dragons for propulsion. Instead it uses several Little Susumu devices to drive it through the water.

The carrier is able to use wyverns at sea by training them to think the ship is an island, thereby conquering their fear of flying over large expanses of water. Its current captain is Castor Vargas and it is named after a World War II carrier.

Roroa Maru
Main Article: Roroa Maru

The first hovercraft of Landia. It rides on a cushion of air and can travel over water and land. As a hovercraft, it is able to traverse any terrain without issues. Though difficult to use and costly to produce, it is seen by the Gran Chaos Empire and the Republic of Turgis as valuable in terms of transport during the winter.

It is named after Roroa Amidonia as it was the Silver Deer company that provided the funds for its development.

Lion-Dog Cannon
It is a mini-cannon powered by gunpowder with a caliber of around 60 millimeters. Primarily by the navy of Nine-Headed Dragon Archipelago for naval battles and due to its light weight, it can be easily mounted even on the smallest boats, and has just enough power to be effectively used against wooden boats and ships by taking advantage at enemies weak points and works well even at a close-range.

Repeating Bolt Thrower
The counter to wyvern cavalry, this is Landia's anti-air weapon. It is similar to appearance to modern rocket artillery battery. The bolts that are shot with this weapon are enchanted with homing magic. Repeating bolt throwers are usually mounted on stationary objects, such as Georg Carmine's castle walls. Dratroopers have proven themselves to be able to neutralize repeating bolt throwers while on descent.

Mechadra
Mechadra is a dragon skeleton that was discovered by Genia Maxwell and reassembled and covered in metallic plates. Much to Kazuya's shock, it was discovered that he could make it move using his Living Poltergeist.

The statue reminds him of a kaiju movie, hence the name of Mechadra.

It made an appearance on Silvan's show. It was Silvan's mount when he fought the 'Death Rhino'. The purpose was to create new products for Roroa to sell.

Little Susumu
Main Article: Little Susumu

The Little Susumu is a propulsion device created by Over-scientist Genia Maxwell. It has the appearance of a large bladeless fan. Powered by a piece of charged Cursed Ore, it rapidly sucks in water or air in front of it and expels in from the rear to propel an object. The mass production model is the Little Susumu Mark V with I-IV being prototypes that were destroyed during testing. It used to propel large ships similar to a screw propeller and to push air into the skirt of hovercrafts. A miniaturized version was developed to be carried on wyverns giving them superior speed than the otherwise faster griffons.

Shock Absorbing Material
Originally created by Genia Maxwell upon the request of "Kazuya Souma" in order to make better and more comfortable transportation vehicles.

The first prototype was created out of the body fat of "Giganto Armadillo", which had powerful shock absorbing qualities. And in order to utilize it, she had processed the fat in a more usable form.

But since the source material was too costly and precious, "Kazuya" asked Dr.Mattis Cosno and his team in the "Cosno Labs" to create a more budget-efficient version of it, which they created by utilizing the cocoons of a certain type of Silkworm and it could easily be mass-produced. But since this material reacted poorly to heat and flames, they applied anti-fire and anti-heat process during the processing of the silk.

Roman Concrete
A mixture of volcanic ash and limestone, creating a construction material for roads, bridges and buildings. Also called ancient concrete, it is strong and flexible enough to withstand cracking from thousands of pounds of constant pressure. It will even withstand the full impact of a charging Rhinosaurus. Stated by Kazuya, that buildings made from this material are still standing after 2,000 years.

Drill
The Drill was jointly developed by the Kingdom of Friedonia, Gran Chaos Empire and the Republic of Turgis. The research team was led by Genia Maxwell, Merula Merlin, Trill Euphoria and Taru Ozumi. Several types of drills of were created. The Little Piercer is a flat faced stamp-type drill powered by Cursed Ore with multiple blades for digging similar to those used to dig subway tunnels. When the front comes in contact with a rock the spinning blades chip away the rock. The current Model is the Little Piercer MK XII however its speed is still too slow. While a conical drill was also possible because the tip quickly wears off it is unsuitable for large drilling projects. A miniaturized type of drill was developed for Kuu's Drill Cudgel which contain cylindrical metal pieces like a hand drill which begin spinning when a button is pressed.

Cycle
Cycles were developed in Friedonia by Genia with directions from Souma but due to complexity issues with the gear and chain mechanisms Taru's help was taken. It was intended to solve the issue of inability to use horses in the carrier Hiryuu but the costs of production were too high and their feasibility was limited as they can only travel in paved roads, commoners can't afford to buy them while nobles have horses, having to keep hands on the handle while peddling can be dangerous as monsters roam outside of cities. Thus Rent-a-Cycle shops were opened within cities renting mostly Tricycles as they can be used without training.

Three-Eyedine
Originally referred as "the drug", is an antibiotic created by the "Three-Eyed" race as a way to combat dangerous pathogens that could cause infectious or epidemic diseases, which even the Light Elemental Magic (aka., Healing Magic) can't cure.

Hypodermic Needle
A device used to safely inject medications or drugs into a patient's bloodstream. Kazuya had contracted Taru Ozumi and other Turgis craftsmen to mass-produce them.
