Most computing systems have one unavoidable side effect: they get hot. That heat is usually treated as a problem and pushed away using cooling systems. Canaan Inc., a technology company that builds high-performance computing machines, is now showing how that same heat can be reused instead of wasted.

In a pilot project in Manitoba, Canada, Canaan is working with greenhouse operator Bitforest Investment to recover heat generated by its computing systems. Rather than focusing only on computing output, the project looks at a more basic question—what happens to all the heat these machines produce and can it serve a practical purpose?

The idea is simple. Canaan’s computers run continuously and naturally generate heat. Instead of releasing that heat into the environment, the system captures it and uses it to warm water. That warm water is then fed into the greenhouse’s existing heating system. As a result, the greenhouse needs less additional energy to maintain the temperatures required for plant growth.

This is enabled through liquid cooling. Instead of using air to cool the machines, a liquid circulates through the system and absorbs heat more efficiently. Because liquid retains heat better than air, the recovered water reaches temperatures that are suitable for industrial use. In effect, the computing system supports greenhouse heating while continuing to perform its primary computing function.

What makes this approach workable is that it integrates with existing infrastructure. The recovered heat does not replace the greenhouse’s boilers but supplements them. By preheating the water that enters the boiler system, the overall energy demand is reduced. Based on current assumptions, Canaan estimates that a significant portion of the electricity used by the servers can be recovered as usable heat, though actual results will be confirmed once the system is fully operational.

This matters because heating is one of the largest energy expenses for commercial greenhouses, particularly in colder regions like Canada. Many facilities still rely heavily on fossil-fuel-based heating and policies such as carbon pricing are encouraging lower-emission alternatives. Reusing computing heat offers a way to improve efficiency without requiring a complete overhaul of existing systems.

The project is planned to run for an initial two-year period, allowing Canaan to evaluate real-world performance factors such as reliability, system stability and maintenance needs. These findings will help determine whether the model can be replicated in other agricultural or industrial settings.

More broadly, the initiative reflects a shift in how computing infrastructure can be designed. Instead of operating as energy-intensive systems isolated from everyday use, computing equipment can contribute to real-world applications. Canaan’s greenhouse pilot highlights how excess heat—often seen as a by-product—can become part of a more efficient and thoughtful energy loop.

In doing so, the project suggests that improving sustainability in technology is not only about reducing energy consumption, but also about finding smarter ways to reuse the energy already being generated.

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.

1. Soulm8te:

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.

2. Greenland 2: Migration

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.

3. Project Hail Mary

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.

4. The Dog Stars

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.

5. Supergirl: Woman of Tomorrow

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.

Final thoughts on the 2026 sci-fi lineup

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.
