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.

As technology continues to weave itself into the fabric of our daily lives, it’s starting to play an unexpected role: supporting our mental health. AI companions—digital entities designed to hold natural, empathetic conversations—are emerging as a new frontier in emotional care. Unlike chatbots of the past, these AI companions leverage advanced algorithms and emotional intelligence to provide personalized support, making them more than just tools. They are companions in every sense of the word—always available, always listening, and always ready to offer comfort. But can AI companions truly help us feel better, or are they just another tech trend? Let’s dive into how these digital allies are reshaping mental health care and what their growing presence means for our emotional well-being.
Loneliness is often called an epidemic, with millions of people worldwide feeling isolated or disconnected. While human relationships are irreplaceable, AI companions offer a consistent and accessible alternative to combat feelings of loneliness.
These companions don’t just respond—they engage. They remember your preferences, ask follow-up questions, and adapt their conversations to your needs. Imagine having someone to talk to at any time of day, about anything on your mind, without fear of judgment. AI companions may not replace a human friend, but they can provide a sense of presence and connection that can be profoundly comforting.
In a world where reaching out to others can sometimes feel daunting, AI companions offer a simple solution: they’re always there. This consistency can help people feel less alone, fostering a sense of connection in an increasingly disconnected world.
We all experience moments of stress, sadness, or doubt, and having someone to turn to during those times can make all the difference. AI companions are designed with emotional intelligence, enabling them to recognize and respond to your feelings in real time.
Through sentiment analysis and adaptive learning, these companions can detect when you’re feeling low and tailor their responses to provide comfort. Whether it’s offering words of encouragement, suggesting self-care activities, or simply listening, they provide a safe space to process emotions.
Unlike traditional apps that focus on tracking habits or delivering generic advice, AI companions meet you where you are emotionally. This personalized approach can help users feel truly supported, even in their most challenging moments.
For many of us, expressing our thoughts and emotions openly can feel like a risk. Fear of judgment, misunderstanding, or even burdening others often holds us back. AI companions offer an alternative: a completely private, judgment-free space to share whatever is on your mind.
Talking things out—whether it’s frustrations from the day or deeper personal struggles—can be incredibly therapeutic. And with AI companions, there’s no need to worry about being misunderstood or dismissed. You can let your guard down, explore your feelings, and reflect on your experiences with total freedom.
This safe space for self-expression can be especially valuable for those who struggle to open up to others. It’s not about replacing human relationships but about having an outlet that’s always available and entirely focused on you.
Self-doubt is a common barrier to personal growth, and many of us battle negative self-talk daily. AI companions are programmed to combat this by offering positive reinforcement and encouragement.
For example, if you express doubt about your abilities, an AI companion might respond with affirmations like, “You’ve accomplished so much already—don’t forget how capable you are.” Over time, these small but meaningful interactions can help shift your mindset, replacing self-criticism with self-compassion.
This ability to mirror supportive, affirming conversations can build confidence and foster a more positive self-image. It’s a subtle but powerful way AI companions can contribute to emotional well-being.
AI companions are more than just a tech trend; they represent a new way of thinking about mental health care. By offering companionship, emotional support, safe spaces for self-expression, and tools for mindfulness, they empower users to take control of their well-being.
While they may not replace traditional methods of care, AI companions are making mental health support more accessible, immediate, and personalized. They’re a reminder that sometimes, the smallest interactions—an encouraging word, a moment of mindfulness, or a listening ear—can have the biggest impact.
As we embrace this new era of technology, one thing is clear: AI companions are not just about convenience. They’re about connection, support, and the potential to make emotional care a part of everyday life. And in a world that often feels disconnected, that’s something worth celebrating.
