Using old coal mines to heat homes? Gateshead is doing it. Their mine-water project—the UK’s largest—draws 15°C water from boreholes, uses heat pumps to boost it to 80°C, and sends that heat through an underground network. The system now warms 350+ homes and 23 buildings.

🇫🇮 FINLAND IS NOW HEATING HOMES WITH INTERNET STRESS SWEAT In Helsinki, they’re using leftover heat from data centers to warm homes. Deep underground, excess heat from servers is supercharged and pumped into the city’s heating system. In a country with more saunas than sense, even your Wi-Fi rage is now part of the energy grid.

This is a Bitcoin mining heated driveway snow melt system. So far, its the biggest I'm aware of. It's about 300' long and utilizes 12 S21 Pro machines in immersion fluid, which heat glycol through a set of brazed plate heat exchangers. The 3/4" PEX is closely spaced and uninsulated so that it has maximum efficiency as a heat dump for mining ops, when desired. It also allows the machines to run at their lowest practical temperature to meet the utilitarian purpose..... snow melt, home heat, and water pre-heating. This mining system is a heat core with amazing secondary uses.

.Cerebras CEO Andrew Feldman explains the benefits of water cooling over air cooling for datacenters: "In Buffalo at a Bills game, there are always three idiots with their shirts off. It's 10 below, and they've got their shirt off. They've been drinking hard, but they're not dead. Why aren't they dead? If you're in the water, and the water's 45 degrees, and you're there for eight minutes, you're dead. Why? It's because water is really good at sucking heat off of heat sources." "The thermal density of water is really high. It rips heat off you. The air doesn't do that. So they can stand there with their shirt off and not be dead." "It's the exact same thing when you're cooling a chip. Water has an ability to pull heat off a heat source that is vastly better than air." "It is more efficient by an order of magnitude to use liquid, water in particular is great and low cost, to pull heat off the back of chips." "Gamers have been doing it forever because they want to run those GPUs hot."

No Water In 45°C Heat! Why Raipur's Rewa Village Is Facing A Brutal Water Crisis Just 28 km from Raipur- one of India’s hottest cities right now- Rewa village is fighting a brutal water crisis in 45°C heat. Despite pipelines laid under the high-profile Jal Jeevan Mission, villagers claim the infrastructure is "just for show" with zero water flowing through. To survive, the panchayat set up a temporary solar pump, but erratic sunlight and a crashing water table have caused the system to collapse. Women and children spend up to 10 hours daily just hunting for a bucket of water. Rewa exposes a glaring, painful gap between government promises and ground reality. #WaterCrisis #RaipurHeatWave #JalJeevanMission #GroundReality #ChhattisgarhNews #Summer2026 #RuralIndia #WaterScarcity

These water trucks are heading from Russia's Rostov toward Ukraine. Due to Russian occupation, Donetsk region has been left without water. The region is currently suffering from extreme heat, and water is almost entirely unavailable. Both drinking and technical water now has to be delivered to more than 1.2 million residents of Donetsk and Makiivka, as well as to half a million people in other towns and cities. There is also a shortage of water for Russian soldiers from the "Center" and "East" military groupings. The hopelessness of the situation is not that there is no way to deliver water - because of leaky pipes, destroyed water intakes, and pumping stations. The real disaster is that the water itself has physically run out. In the Donetsk coal basin, nearly all mines have been flooded during the occupation. As long as the mines were operating or kept in dry conservation, water was regularly pumped out. But after Russian forces occupied the city in 2014, they first sold all the equipment from these mines for scrap metal, and then simply flooded everything. Flooding the mines means stopping the pumping of water from them - disrupted water horizons, underground rivers, etc. do their job. The tragedy is that once a mine fills up, its contents mix with these groundwater horizons. The resulting excess pressure forces this mine water to rise to the surface, creating huge rust-colored swamps - that's iron oxide. As a result, all water horizons in Donbas are now unfit for any use. This is a massive environmental catastrophe that no one is talking about.

Just watched Jane Street data centre tour and most entertaining part was team nerding out on air cooling vs. water cooling. Filters to ensure water perfectly uniform and flow is consistent to move heat. Ultrasonic monitors to measure the flow. The water has specific ratio of propylene glycol (an alcohol) to prevent bacteria or algae growth that can block heat transfer from GPUs to cold plates.

Gaza’s water crisis is already catastrophic. Now when, out of complete necessity due to the lack of funding, The Sameer Project is forced to stop our water distributions, it will become unimaginable for the families who depend on us. In the brutal summer heat, water is survival. And without enough donations, we cannot keep bringing it to the communities that need it. Please help Gaza through this manufactured suffering caused by the occupation. Donate to our Food and Water Campaign. Other ways to donate include: (Paypal option, please make sure to add a message saying "WATER") (Venmo option, please make sure to add a message saying "WATER")

Data centres are energy hungry but what if we could use their waste heat to heat our homes? That's exactly what happens in places like Finland: Cities are tapping the vast amounts of waste heat generated by data centres, and feeding it into district-heating networks.

Mayor Zohran Kwame Mamdani: Anyone who has stood on a subway platform in August knows that our stations do not just get hot. They turn into underground saunas. This new thermal energy study will explore the possibility of using the heat that accumulates in this station over the summer to heat the municipal campus above us come winter. We would capture heat in boreholes underground and install a system of circulating pipes that use the heat to warm our municipal offices. This would be the first thermal energy system of its kind in any American transit system, a historic feat that would not only help the city to save money and limit steam consumption, but help us mitigate the extreme level of heat in our subway stations.

☀️ The forecast is heating up. Temperatures are already high and expected to climb. Stay safe in the heat: ➡️ Drink plenty of water and hydrate before heading outside. ➡️ Take regular breaks in a cool or shaded area. ➡️ Check on children, older adults, and anyone who may be more vulnerable to the heat. Know the signs of heat exhaustion and heat stroke. Heat exhaustion can progress to heat stroke, which is a medical emergency. If someone is showing signs of heat illness, take it seriously and act quickly. Stay cool, California. #CALFIRE #HeatSafety #HeatAwareness #StayCool #StaySafe

Kyiv, power outages. Twins Yaroslav and Sviatoslav are climbing the stairs to the 7th floor — the toddlers are two years old. Russians continue to terrorize Ukraine, deliberately destroying the energy infrastructure of cities. Millions of people in Ukraine are right now left without electricity and heat. Homes are cold and dark. Not only heating and power are down, but also water supply and sewage systems. Outside, it’s −15°C. The situation is critical. Thank you to everyone who is helping to keep Ukraine warm right now. You are helping us save lives and endure. 📹: tetyashkaa/Instagram

Ocean Heat Source 04: Now that I’ve pinned down the abyssal warming pattern, it’s time to investigate possible sources. I’m working through five main possibilities: 1. Adiabatic compression : could the water only appear warmer because it moved deeper and got squeezed? This one is already looking weak. 2. Redistribution and isopycnal heave: could density layers be moving up and down and shifting existing heat around? 3. Antarctic Bottom Water and overturning: could changing deep ocean circulation be carrying warmer water into the abyss? 4. Geothermal and hydrothermal heating : could heat be entering from the seafloor, ridges, or vents? 5. Electromagnetic induction and ohmic heating: could changing magnetic fields drive electric currents, and could enough of that electrical energy turn into heat? I’ll need my electromagnetic solver to finish that last test. Now, we get to see which mechanisms survive testing.

#WATCH | Gurugram, Haryana: On heat wave, Vice Chairman of internal medicine, Medanta Gurugram, Dr Sushila Kataria says, “…there’s a limit of the body’s thermostat regulation, beyond which, exposure to heat causes loss of water and salt. The initial symptoms of heat exhaustion include headache, muscle cramps, nausea etc. In case of severity, it leads to heat stroke…if a heat stroke patient is not attended to, it starts affecting the brain, kidney. Most vulnerable to this are children, the elderly, people with comorbidities, and people working in the field. If not necessary, do not step out between 10 am and 5 pm…Ideal hydration options are water, coconut water, ORS. Drinks like tea and coffee drain even more water from the body. Wear cotton, loose, and light-coloured clothes. People who take medication for lung, heart, and kidney issues must routinely consult their respective doctors during weather changes…”
