The technology of the Duna Universe is one of its most iousubopitic and different components when compared to other prominent scientific worlds. Due to the Butterial Jihad, which has been going on for thousands of years before the events of Frank Herbert's first novel "Duna", without "thinking machines" are not allowed within the empire. This means that there are no robots and there are no computers, even when used to run a hipwar through the dark cavity of space.

That said, there are still many examples of advanced futuristic technology in Duna, only those outside the computer area. These include spaceships themselves, cloning technology and advanced genetic manipulation and the various vehicles used in Arakis. Another usual part of the technology in the Duna Universe is the suspension, a device that allows equipped items to float in the defiance of gravity. Suspensors often refer to the books "Duni" and are often seen in Denis Vilnev's "Duna" filmsWith everything, from lamps to furniture that are increasing with the devices. These suspensions are also what it allows Baron Vladimir Harcon to fly to "Duna".

The baron wears an item called the suspension belt, which is attached to the left of the suspension devices that allow it to hover around without the need to use the legs. It gives him away, almost an awkward effect, which contributes to his aura as one of the basic villains of the Duna universe. Suspensors tie in other areas during the franchise, also all have to do with a scientific concept called Holtsman effect.

Within the Duna Universe, there is a fictional scientific concept called Holtsman effect. That principle is the explanation of Frank Herbert behind most of the franchise technology, from suspensors that allow Baron Harconen to fly to the engines that the power of power and allow them to fold space. Since it is a scientific idea, there is no way to specifically explain how it works, but the basic idea is that it refers to the tension between subatomic particles. Something called the Holtsman field, created by a Holzmann field generator, authorizes both suspended and personal shields that characters wear to "Duna".

Holzmann's engines also allow guild navigators and their ships to fold the space or undermine the normal dimensions of space time to travel over huge distances incredibly fast. In other words, the majority of the greatest scientific technologies in Duna are explained through the Holtsman effect.

Narratively, of course, this was primarily a way for Herbert to justify the future of a non-computer. Feudalist aesthetics, Sword-fight in "Duna", Other cornerstone of his universe are also possible along with the galactic journey in space, mainly because of this basic sense.
