Police in Macau recently detained a humanoid robot after it frightened an elderly woman on a public street. The unusual encounter quickly spread online, prompting jokes about what some called the world’s first “robot arrest”.
On the evening of March 5, the robot was taken away by officers after the encounter triggered alarm among bystanders. Videos circulating on social media show an elderly woman confronting the robot on a sidewalk, visibly distressed and shouting that her “heart is pounding” while demanding to know why such “nonsense” was happening on the street. In the clip, the robot raises both hands toward the woman after she lashes out in fear — a gesture many viewers interpreted as a sign of apology.
Shortly afterwards, two officers from the Macau Public Security Police Force were seen escorting the robot and a man believed to be its operator away from the area. An officer is seen placing his right hand on the robot’s shoulder — the same posture police often use when presenting arrested suspects in official photographs.
That scene quickly spread online, fuelling jokes about what some called the world’s first “robot arrest”.
Photos shared online show a humanoid robot with long limbs and exposed mechanical joints, built from a black metallic frame without an outer shell. In dim lighting, several commenters said it resembled a “moving skeleton” — a striking sight for pedestrians encountering it unexpectedly on the street.
Witnesses said the woman appeared severely shaken and an ambulance was eventually called to take her to the hospital.
The incident also sparked discussion online about robots operating in public spaces. Some commenters argued that experimental technologies should be tested in controlled environments, while others said machines moving through public areas should have clearer designs or safety measures to avoid alarming pedestrians.
It remains unclear who deployed the robot or what purpose it was serving in the area at the time of the incident. Authorities have not released further details about the device or whether any action was taken following the encounter.

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.
