Turning computing heat into a practical heating solution for greenhouses.

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.

In an era where social media reigns supreme, influencers have emerged as powerful players in the marketing game. They have the ability to sway opinions, drive trends, and create waves of engagement that brands can only dream of. But not all influencers are created equal; they come in various shapes and sizes, each with a unique approach to connecting with their audience. Under standing the different types of influencers can illuminate how they impact our daily lives and the choices we make. Let’s dive into the captivating world of influencers and explore the diverse categories that define them.
When you think of influencers, mega influencers are often the first that come to mind. These are the A-list celebrities, athletes, and global icons with millions of followers on platforms like Instagram, TikTok, and YouTube. Their immense reach allows brands to tap into vast audiences, making them highly sought after for endorsements.
Mega influencers have the power to generate instant buzz around a product or campaign. Their celebrity status lends credibility, and fans are often eager to emulate their lifestyles. However, this type of influencer can come with a hefty price tag, making them suitable for brands with substantial marketing budgets.
Just below the mega influencers are macro influencers, who typically boast between 100,000to 1 million followers. While they may not have the same level of fame as celebrities, macro influencers often command a loyal and engaged audience. They are usually experts in specific niches, such as fitness, beauty, travel, or technology.
Macro influencers combine reach with relevance. Their targeted expertise allows brands to connect with specific demographics, making them an ideal choice for campaigns aimed at niche markets. Their followers often view them as relatable and trustworthy, which can lead to higher engagement rates.
Micro influencers are the rising stars of the influencer world, typically having between 10,000 to 100,000 followers. What sets them apart is their authentic connection with their audience. They often have a more intimate relationship with their followers, leading to higher engagement and trust.
Brands are increasingly turning to micro influencers for their ability to create genuine conversations around products. The cost-effectiveness of partnering with micro influencers also allows brands to run multiple campaigns across different influencers, amplifying their reach while maintaining authenticity.
At the bottom of the influencer hierarchy are nano influencers, who have 1,000 to 10,000 followers. While their follower count may be modest, nano influencers often possess a highly engaged audience that views them as close friends, families or peers rather than celebrities.
Nano influencers are perfect for brands looking to create grassroots campaigns. Their genuine enthusiasm and relatability can lead to strong word-of-mouth marketing. Engaging with nano influencers often comes at a lower cost, making them an attractive option for small businesses and startups.
Brand ambassadors are influencers who have a long-term relationship with a brand, often representing them across multiple campaigns. They can fall into any of the previous categories but are distinguished by their commitment to the brand and its values.
By cultivating brand ambassadors, companies can create consistent messaging and foster loyalty among customers. These influencers often resonate with audiences more deeply, as they embody the brand’s identity and promote its products authentically over time.
The world of influencers is as diverse as it is dynamic, with each type offering unique advantages for brands looking to connect with consumers. From the glitzy allure of mega influencers to the genuine relatability of nano influencers, understanding these categories can help brands make informed choices in their marketing strategies. As the digital landscape continues to evolve, the role of influencers will only grow, shaping trends and driving engagement in ways we are just beginning to comprehend. By leveraging the right type of influencer, brands can effectively navigate this vibrant ecosystem, ensuring their message resonates with the audiences that matter most.
