Compressed air is used across factories, data centers and industrial plants to move materials, cool systems and power tools. Once it has done that job, the air is usually released — and its remaining energy goes unused.
That everyday waste is what caught the attention of a research team at Chung-Ang University in South Korea. They are investigating how this overlooked airflow can be harnessed to generate electricity instead of disappearing into the background.
Most of the world’s power today comes from systems like turbines, which turn moving fluids into energy or solar cells, which convert sunlight into electricity. The Chung-Ang team has built a device that uses compressed air to generate electricity without relying on traditional blades or sunlight.
At the center of the work is a simple question: what happens when high-pressure air spins through a specially shaped device at very high speed? The answer lies in the air itself. The researchers found that tiny particles naturally present in the air carry an electric charge. When that air moves rapidly across certain surfaces, it can transfer charge without physical contact. This creates electricity through a process known as the “particulate static effect.”
To use that effect, the team designed a generator based on a Tesla turbine. Unlike conventional turbines with blades, a Tesla turbine uses smooth rotating disks and relies on the viscosity of air to create motion. Compressed air enters the device, spins the disks at high speed and triggers charge buildup on specially layered surfaces inside.
What makes this approach different is that the system does not depend on friction between parts rubbing together. Instead, the charge comes from particles in the air interacting with the surfaces as they move past. This reduces wear and allows the generator to operate at very high speeds. And those speeds translate into real output.
In lab tests, the device produced strong electrical power. The researchers also showed that this energy could be used in practical ways. It ran small electronic devices, helped pull moisture from the air and removed dust particles from its surroundings.
The problem this research is addressing is straightforward.
Compressed air is already everywhere in industry, but its leftover energy is usually ignored. This system is designed to capture part of that unused motion and convert it into electricity without adding complex equipment or major safety risks.
Earlier methods of harvesting static electricity from particles showed promise, but they came with dangers. Uncontrolled discharge could cause sparks or even ignition. By using a sealed, turbine-based structure, the Chung-Ang University team offers a safer and more stable way to apply the same physical effect.
As a result, the technology is still in the research stage, but its direction is easy to see. It points toward a future where energy is not only generated in power plants or stored in batteries, but also recovered from everyday industrial processes.

Grab your popcorn—the 2026 sci-fi movie slate is stacked. We’re getting everything from post-apocalyptic survival films to AI thrillers, plus a big-space adventure and a fresh DC superhero story. Some films launch new worlds, others expand familiar ones, but all of them aim to leave an impression, but all of them look like the kind of movies you’ll want to talk about after the credits.
Here are five upcoming sci-fi movies to mark on your calendar.
Release Date: January 9, 2026
Director: Kate Dolan
Stars: Lily Sullivan, David Rysdahl and Claudia Doumit
If you like your sci-fi with a creepy edge, Soulm8te is very much in that lane. A spin-off from the M3GAN universe, the film follows a man grieving the loss of his wife who turns to an AI android to ease the pain. At first, it seems to help. The connection feels real, even comforting. But before long, it becomes a little too real and slips into something far more dangerous. What makes Soulm8te unsettling is how close it feels to the present. AI companions are no longer science fiction, and the film plays with that reality in a way that feels intimate rather than futuristic. Directed by Kate Dolan, the story stays on quiet unease instead of spectacle, allowing tension to build as affection turns possessive and attachment becomes dangerous. The film is produced by Allison Williams and James Wan, both closely involved in the hit horror franchise M3GAN, and their experience with technology-driven horror is clearly felt here. Fans of grounded, psychological sci-fi should keep this one on their radar.
Release Date: January 9, 2026
Director: Ric Roman Waugh
Stars: Gerard Butler, Morena Baccarin, Amber Rose Revah, Sophie Thompson, Trond Fausa Aurvåg
Back in 2020, Greenland introduced audiences to John Garrity (Gerard Butler), a father racing against time to save his family as comet fragments threatened to wipe out life on Earth. The film ended with survivors heading into bunkers deep in Greenland, hanging on to the last thin thread of hope. This sequel follows the Garrity family as they leave the safety of underground shelters and face a world that no longer resembles home. The setting moves across a battered Europe, where every decision carries weight and every journey feels uncertain. Rather than repeating the ticking-clock chaos of the original, Migration leans into endurance, exhaustion and the question of whether rebuilding is even possible. It’s a post-apocalyptic movie about movement, loss and the cost of starting over.
Release Date: March 20, 2026
Director: Phil Lord & Chris Miller
Stars: Ryan Gosling, Milana Vayntrub, Sandra Hüller
Based on Andy Weir’s best-selling novel, Project Hail Mary is shaping up to be one of the most talked-about space survival films of 2026. Ryan Gosling stars as Ryland Grace, an unlikely astronaut whose journey into space begins with confusion rather than heroics. Grace, a former junior high science teacher, wakes up alone on a spacecraft, cut off from Earth and missing key memories about how he got there. As pieces slowly fall into place, so does the scale of the problem he’s been sent to solve. The film blends real science with high-stakes isolation, balancing quiet moments with the pressure of a mission that affects the entire planet. Directed by Phil Lord and Chris Miller, Project Hail Mary promises tension, curiosity and a heavy dose of human vulnerability set against the vastness of space.
Release Date: March 27, 2026
Director: Ridley Scott
Stars: Jacob Elordi, Josh Brolin
The Dog Stars strips the apocalypse down to its bare essentials. Based on Peter Heller’s novel of the same name, the film features a screenplay by Mark L. Smith and Christopher Wilkinson, known for The Revenant and Ali. The setup of The Dog Stars is simple and bleak: a virus has erased most of humanity. What’s left is silence, abandoned airfields and roaming scavengers known as the “Reapers” who prey on the few survivors left behind.
Jacob Elordi plays Hig, a pilot living in isolation with his dog and a heavily armed companion. His days follow a strict routine, broken only by short flights in his aging Cessna. That fragile balance shatters when a distant radio signal breaks through the quiet. It’s the first real sign of life he has heard in years, and it draws him toward a journey that could change everything. Directed by Ridley Scott, the film focuses less on large-scale destruction and more on loneliness, hope and the risk of reaching out in a broken world. The result is a post-apocalyptic thriller that feels intimate, reflective and quietly tense.
Release Date: June 26, 2026
Director: Craig Gillespie
Stars: Milly Alcock, Jason Momoa, Matthias Schoenaerts
Supergirl: Woman of Tomorrow offers a very different take on the DC universe. This is a cosmic sci-fi story first, superhero film second. Kara Zor-El is older, tougher and shaped by memories of a world she lost. Unlike her cousin Superman, she remembers the destruction of Krypton clearly, and that history weighs heavily on her. The film follows Kara as she crosses paths with a young alien seeking justice, pulling her into a dangerous journey across distant worlds. Rather than focusing on Earth-saving spectacle, the story explores identity, grief and what heroism looks like far from home. With Milly Alcock stepping into the role, Supergirl 2026 aims to expand DC’s sci-fi side while giving the character emotional depth rarely seen on screen.
One reason science fiction movies stick with us is that they ask big questions in a way that feels personal. What happens when tech starts filling emotional gaps? What does survival look like when the world doesn’t bounce back? And how far would you go to save everyone you’ve ever known? If you’re looking for 2026 sci-fi movies that range from gritty to hopeful to unsettling, this lineup has you covered.
