In addition to providing computing, data storage and AI services, the new data center will the the World’s Largest District Heat Recovery Scheme. Excess heat produced by the datacenter servers will be captured and routed into the local district heating network serving Espoo, Kirkkonummi, and Kauniainen. The system is set to cover 40% of the annual heating needs for roughly 250,000 households. Reusing this heat is projected to eliminate 400,000 metric tons of CO₂ emissions annually by displacing fossil fuel usage because the power for data center is sourced entirely from renewable energy.

Construction at Hepokorpi has progressed steadily through phases of ground preparation, rock excavation, and steel frame erection, and some of the first building are already built.

The data center needs a lots of power. While Microsoft does not publicly disclose precise, operational server power capacity figures for individual datacenter halls, official environmental impact assessments and project plans provide clear technical estimates: Estimated Electrical Capacity (IT & Infrastructure Load): Up to ~100 MW (with environmental impact assessments for the broader site evaluating total capacity scales around 100 MW to 200 MW across various expansion phases). For this reason the data center seems to be connected to a big new transformer connected to 400 kV power line. That would mean up to almost 300A current taken from 400 kV three phase power line.

It looks the voltage is dropped to 110 kV level that is then sent to the data center buildings, although. Fingrid’s newly built main Hepokorpi primary transmission substation actually steps down the 400 kV grid power to 110 kV using compact Gas-Insulated Switchgear (GIS) technology. From there, regional sub-transmission lines and Caruna’s local distribution network route that 110 kV into Microsoft’s on-site transformers. On-site step-down transformers convert 110 kV to 20 kV (a standard medium-voltage level used in Nordic industrial facilities and distribution networks) that is most probably routed around the campus with medium voltage cables.

There it would be dropped with another transformer to the voltage level used by the data center computers. While Microsoft keeps precise proprietary server supply specs confidential, these follow standard OCP / Open Compute Project hyperscale architectures): Dry-type transformers step the 20 kV down to 400 V 3-phase AC line-to-line (230 V AC line-to-neutral). This feeds the Uninterruptible Power Supply (UPS) units and Power Distribution Units (PDUs). In Europe typical primary operational voltage feeding the rack server power supplies is 400 V / 230 V AC (3-phase 400 V AC input, delivering 230 V AC per phase). Server rack Power Supply Units (PSUs) convert 230/400 V AC directly down to 48 V DC distributed along the rack busbars. Modern high-density AI nodes (e.g., NVIDIA MGX/DGX racks used in Microsoft Azure AI clusters) rely on 48 V DC (lower losses than legacy 12V systems).

Microsoft’s Finland data-center project demonstrates how computing infrastructure can become part of a city’s heating system. Microsoft says waste heat (roughly 100 MW to 175 MW) from its Finnish data centers will eventually provide heat for around 250,000 people through district heating networks serving Espoo, Kauniainen and Kirkkonummi. The system uses heat pumps to raise the temperature of heat recovered from the data-center cooling system before it is transferred into the municipal heating network. I suspect that this building to be part of the heat pump system.

The recovery system requires infrastructure and energy — but that waste heat which would otherwise be rejected can be put to productive use. This approach could become increasingly valuable in colder regions where district heating is already widespread. Microsoft says the system is scheduled to begin operations in 2027. Combined with Microsoft’s sister facility in Kirkkonummi (Kolabacken), the joint campus footprint accounts for up to 350 MW of total thermal heat recovery for Fortum’s regional district heating grid.

The money will be used to develop data centres as well as supporting infrastructure, and represents the search engine giant’s largest single investment in Europe to date. “This is Google’s largest single investment in Europe and a testament to Finland’s leadership in responsibly building AI infrastructure,” the company said on Wednesday.

The AI infrastructure build-out would involve the development of three new data centres in the country’s north. The locations were selected based on the availability of electrical power and cold climate (temperature ​can drop well below minus 10 degrees Celsius (14 degrees Fahrenheit) in winter). After investment Google has operations spanning Hamina (current data center site), Kajaani, Muhos, and Vaala.

The investments will include data centres, electricity grid improvements and clean energy and battery projects driving services such as Gemini, Search, Maps and YouTube, Google ​said in a statement. The investment is expected to ⁠contribute some €3.6 billion to Finland’s gross domestic product during the construction phase. The Google investment is expected to support more than 37,000 jobs during construction and boost Finland’s GDP by €3.6bn a year, according to Google. Construction is set to take place in 2027 and 2028.

Illustration made with Google Gemini AI:

There is a question how this will affect the price of the electrical power. Some see this is a right time to plan to build a new nuclear power plant. Building new nuclear facilities typically involves enormous upfront costs, long construction times, and market uncertainty over long horizons. Alongside facility expansion, Google is partnering with local energy companies (including Fortum) to secure power supplies, develop new generation capacity, and support long-term grid stability and decarbonization in Finland. Google has signed a 22-year Power Purchase Agreement (PPA) with Fortum. This long-term commitment supports the lifetime extension of the Loviisa nuclear power plant. While Google is also backing onshore wind power (629 MW) and grid-balancing battery storage (a 94 MW system in Kajaani), data centers require steady baseload power even in cold weather without wind. Nuclear power fills this critical need for predictable, zero-emission electricity.

The “Fakebook” Side (Information Quality)

• Algorithmic Engagement: Content optimized for rage, outrage, and high click-through rates systematically outperforms nuanced, accurate information.
• Policy Shifts: Decisions like scaling back independent third-party fact-checking programs in major markets have cleared the path for unchecked deepfakes, AI-generated slop, and misinformation to flood user feeds.
• Synthetic Content: Generative AI tools have made mass-producing believable nonsense (from fake technical schematics to fabricated news snippets) trivial, polluting groups and comment sections. As is typical with electronic schematics posted on Facebook, it seems like the author intentionally includes errors or just post bad AI slop solely to prompt you to comment and point them out. The goal is to boost their visibility, since on Facebook, that depends on the number of reactions a post receives—regardless of what those reactions are.

The “Farcebook” Side (Platform Usability & Dynamics)

• Ad-to-Content Ratio: Main feeds are increasingly saturated with sponsored posts, “Suggested for You” algorithmic junk, and scam advertisements rather than updates from actual friends.
• Dead Internet Vibe: Automated bot networks, AI engagement pods, and stolen/reposted content account for a huge fraction of daily interactions, making genuine human discussion harder to find.
• Context Collapse: People share far less personal content now than they did a decade ago. The platform has pivoted from a personal social network into a passive broadcast wire for algorithmic noise.

It leaves active users facing a choice between filtering out the signal from the noise or abandoning feed-based scrolling altogether in favor of niche, direct communication tools.

There are many other countries where you can see a partial solar eclipse. Hundreds of millions of people across Europe will get the chance to see a partial or total eclipse on Wednesday when the Moon passes in front of the Sun. There will be 94% coverage in Dublin and 83% in Oslo, Norway. Montreal will see an 18% bite out of the sun, tapering to 9% in New York and 2% in Norfolk, Virginia.

Finland to see partial solar eclipse on 12 August 2026. The solar eclipse will take place when the Sun is low above the west-northwestern horizon, meaning viewing opportunities will depend on local weather conditions and the position of buildings, trees and hills. The event in Finland is set to begin before 8pm and reach its peak just before 9pm.

Viewing Conditions Strategy
* Clear Western Horizon: Because late afternoon/evening eclipses occur lower in the sky, scout a viewing spot (a hill, field, or elevated deck) with an unobstructed view toward the west/southwest free from tall trees or buildings.
* Check Cloud Coverage: Plan a backup location 30–60 minutes away in case local cloud cover threatens your view.

Many people want to see the solar eclipse. A few warnings needs to be kept in mind to stay safe. ⚠️

Looking directly at a solar eclipse without proper protection can cause permanent eye damage.
Whether you’re in the path of totality or viewing a partial eclipse across Europe or North America, you must protect your eyes or use indirect projection. If you plan to look directly toward the Sun, standard sunglasses will not protect your eyes regardless of how dark or polarized they are. Use ISO 12312-2 Certified Viewers: Check that your solar glasses or handheld viewers are explicitly stamped with ISO 12312-2 compliance: ISO 12312-2:2015, “Eye and face protection — Sunglasses and related eyewear — Part 2: Filters for direct observation of the Sun.” The ISO 12312-2 standard is the main international benchmark for handheld, non-magnifying solar viewers used for direct observation of the Sun.
Inspect the Filters: Before looking up, check your lenses for scratches, tears, or pinholes. Discard damaged glasses immediately.
Putting Them On: Turn away from the Sun, put the glasses on securely over your eyes (or over prescription glasses), and then look up. Turn away before removing them.

“Do not look at the Sun through a camera lens, telescope, binoculars, or any other optical device while wearing eclipse glasses or using a handheld solar viewer,” the US space agency wrote in a post about eclipse safety.

If you don’t have ISO-certified glasses, use indirect projection to safely view the eclipse cast onto a surface. There are several DIY methods for this:
* Kitchen Colander: Hold a standard kitchen colander 1–2 feet above a sheet of white paper or the ground with your back to the Sun. Each small hole will project a mini crescent-shaped image of the eclipsed Sun.
* Pinhole Cardboard: Take two pieces of cardboard or stiff paper. Punch a clean pinhole in one piece. Stand with the Sun behind your shoulder, and hold the pinhole card so sunlight shines through the hole onto the second card acting as a screen.
* Natural Tree Shade: Find a nearby leaf-covered tree. The small gaps between the leaves act as natural pinhole projectors, casting dozens of mini crescent eclipses onto the ground.

What if you want to take a picture of solar eclipse? Many will be hoping to capture the celestial phenomenon on their phones or cameras. You need to be also careful with cameras. Experts have warned that pointing a digital camera or smart phone camera lens directly at the Sun could cause permanent damage to a device. ⚠️
Pointing your smartphone or camera at the Sun can permanently damage internal sensors, experts warn.
Direct exposure to the Sun, even when partially covered by the Moon, risks overheating a smartphone or digital camera. Pointing a camera at the Sun for a prolonged period could even burn parts of the internal sensor, creating dead pixels that cannot be repaired. “The best practice would be to hold a pair of eclipse glasses in front of your phone’s lenses when photographing the Sun at any point other than totality.”

A solar eclipse creates a rapid, temporary interruption in solar radiation, triggering immediate physical, biological, and technological changes across the path of shadow. Here is a list of some effects on nature and ecosystems:

Atmospheric and Weather Changes
Temperature Drop: Ambient temperatures typically fall by 5°F to 15°F (3°C to 8°C) within minutes as direct sunlight vanishes, with the sharpest decline occurring right at totality.
Eclipse Wind: As the ground rapidly cools under the Moon’s shadow, localized air convection changes, causing winds to quiet down or abruptly change direction before picking up again as light returns.
Humidity and Cloud Shifts: Relative humidity spikes near the surface. Low-altitude cumulus clouds, which rely on rising warm air from sun-heated ground, frequently dissipate during the eclipse.

Animal and Wildlife Behavior
Diurnal Species (Daytime): Songbirds stop singing and head for roosts, honeybees cease foraging and return to hives, and livestock line up to head toward their barns, treating totality as sudden nightfall.
Nocturnal Species (Nighttime): Crickets, frogs, owls, and bats mistake the darkness for dusk, initiating night calls and nocturnal foraging early.
Disoriented Navigation: Species reliant on solar cues or light patterns—such as migratory birds, dragonflies, and marine organisms near the water surface—often freeze or temporarily lose direction during the shadow’s passage.
Anxiety and Grouping: Zoo observations note unusual social behaviors during totality; for instance, flamingos form protective huddles around chicks, while chimpanzees have been observed climbing high structures to gaze at the darkened sky.

Plant Life
Photosynthesis Shutdown: Photosynthetic activity halts sharply as solar irradiance drops.
Stomatal Closure: Pores on leaves (stomata) begin closing to conserve water, temporarily slowing down plant transpiration until full daylight returns.

Effects on Humans and Infrastructure:

Vision Safety
Solar Retinopathy: Looking directly at the Sun’s exposed disk—even during a partial eclipse—causes irreversible thermal damage to retinal photoreceptors. Because the retina lacks pain receptors, damage occurs without immediate warning. Standard sunglasses offer zero protection; viewing requires specialized ISO 12312-2 certified eclipse glasses.

Psychological and Emotional Impact
Awe and Collective Experience: Totality routinely triggers strong psychological reactions, including goosebumps, vocal emotional outbursts, and an intense sensation of awe. Psychological studies show that experiencing a total eclipse fosters elevated feelings of social connection and awe among crowds.

Electrical Grids and Logistics
Solar Power Fluctuations: Electrical grid operators must manage sudden drop-offs in solar energy generation followed by rapid “ramp rates” as the Moon moves past the Sun, requiring hydro, natural gas, or battery reserves to balance the grid. Britain’s biggest energy supplier urges people not to use washing machines or dishwashers during solar eclipse because the shutdown in solar energy generation will coincide with a usual surge in electricity demand in the UK.
Cell Towers and Traffic: Massive influxes of observers into narrow paths of totality often overload rural telecommunication networks and cause severe highway congestion before and after the event.
