How do space windshield wipers from science fiction work compared to regular ones?

In some science fiction movies like 'Star Trek', there are advanced energy - based systems that act like windshield wipers for spaceship viewports. They use force fields or directed energy beams to clear away debris or any substances that might obstruct the view, rather than the traditional mechanical wipers we have on Earth vehicles.

Space marines are usually more highly specialized. While regular soldiers might be trained for general combat on Earth, space marines are trained for the unique challenges of space, like zero - gravity combat and dealing with alien life forms.

Literary science fiction often focuses more on the writing style and the exploration of deep themes. Regular science fiction might be more plot - driven. For example, in literary science fiction, the language can be more complex and evocative, like in 'The Dispossessed' by Ursula K. Le Guin. It uses the science fiction setting to really dig into social and political ideas.

In science fiction, space station rooms can have all kinds of futuristic features like force fields instead of doors. In real - life, we have mechanical or airlock doors.

Science fiction humor novels often use humor to approach the science - fictional concepts. Regular ones might be more serious about world - building and scientific ideas. For example, a regular SF novel might focus on the details of a spaceship's technology, while a humor SF novel could make a joke about the spaceship being held together with duct tape.

Dark science fiction novels often have a more pessimistic view of the future. For example, in regular science fiction, the future might be full of technological wonders that improve humanity. But in dark science fiction like 'The Handmaid's Tale' by Margaret Atwood, it shows a future where women are oppressed in a totalitarian regime. Dark science fiction also tends to explore the darker side of human nature more deeply, like in 'Lord of the Flies' which has elements of this genre. It shows how quickly humans can descend into savagery.

Psychedelic science fiction books often focus more on the inner mental states of characters and how they perceive reality. Regular science fiction may be more about technological advancements or exploring new worlds in a more straightforward way. For example, in psychedelic science fiction, the narrative might jump between different states of consciousness, while regular science fiction might be more linear in its storytelling.

Christian science fiction novels often have a spiritual or religious underpinning. For example, they might deal with concepts like the battle between good and evil in a spiritual sense, which regular science fiction may not focus on as much.

The main difference is that metaphysical science fiction novels tend to explore the non - physical and philosophical aspects of existence. They might question the very fabric of reality, consciousness, and the relationship between the self and the universe. Regular science fiction novels usually deal with more tangible things like the development of new technologies or the exploration of outer space. For example, 'Neuromancer' is a metaphysical science fiction as it looks at how technology affects our perception of self, while a regular science fiction like 'Star Trek' often focuses on adventures in space and the interaction with different alien species, with less focus on these deeper metaphysical ideas.

The tone and atmosphere can also be different. Erotic science - fiction may create a more sensual or passionate mood, while regular science - fiction might aim for a more cerebral or action - oriented feel. For instance, an erotic science - fiction might describe the allure of an alien species in a sexual way, whereas a regular one would be more interested in their technological capabilities. Additionally, the target audience can vary. Erotic science - fiction may appeal to those interested in exploring sexual themes within a speculative context, while regular science - fiction has a broader general audience interested in the genre's typical themes.
