This German Data Center Wants To Heat Your House With Its Servers

This German Data Center Wants To Heat Your House With Its Servers | Farming, Forests, Water & Fishing (No Petroleum Added) | Scoop.it
The data centers that power the Internet use more energy than the entire country of India. Most of that energy is lost as waste heat. That fact inspired an idea: Why not use a network of servers to heat homes?

Cloud & Heat, a cloud infrastructure company in Germany, stores server cabinets in houses and apartment buildings. While the servers crunch data, the excess heat is used to warm up the homes in the winter and provide hot water all year.

The service has a second major benefit: a huge chunk of the energy used in data centers goes to air conditioning to keep the machines cool. When the servers are distributed in homes instead of a single building, the company can eliminate the need for cooling. That, in turn, saves money and makes the service cheaper for customers.

Single-cell phytoplankton in the ocean are responsible for roughly half of global oxygen production

Single-cell phytoplankton in the ocean are responsible for roughly half of global oxygen production | Farming, Forests, Water & Fishing (No Petroleum Added) | Scoop.it

In a paper published in PNAS on Monday November 24, scientists laid out a robust new framework based on in situ observations that will allow scientists to describe and understand how phytoplankton assimilate limited concentrations of phosphorus, a key nutrient, in the ocean in ways that better reflect what is actually occurring in the marine environment. This is an important advance because nutrient uptake is a central property of ocean biogeochemistry, and in many regions controls carbon dioxide fixation, which ultimately can play a role in mitigating climate change.

 

"Until now, our understanding of how phytoplankton assimilate nutrients in an extremely nutrient-limited environment was based on lab cultures that poorly represented what happens in natural populations," explained Michael Lomas of Bigelow Laboratory for Ocean Sciences, who co-led the study with Adam Martiny of University of California - Irvine, and Simon Levin and Juan Bonachela of Princeton University. "Now we can quantify how phytoplankton are taking up nutrients in the real world, which provides much more meaningful data that will ultimately improve our understanding of their role in global ocean function and climate regulation."

 

To address the knowledge gap about the globally-relevant ecosystem process of nutrient uptake, researchers worked to identify how different levels of microbial biodiversity influenced in situ phosphorus uptake in the Western Subtropical North Atlantic Ocean. Specifically, they focused on how different phytoplankton taxa assimilated phosphorus in the same region, and how phosphorus uptake by those individual taxa varied across regions with different phosphorus concentrations. They found that phytoplankton were much more efficient at assimilating vanishingly low phosphorus concentrations than would have been predicted from culture research. Moreover, individual phytoplankton continually optimized their ability to assimilate phosphorus as environmental phosphorus concentrations increased. This finding runs counter to the commonly held, and widely used, view that their ability to assimilate phosphorus saturates as concentrations increase.

 

"Prior climate models didn't take into account how natural phytoplankton populations vary in their ability to take up key nutrients, "said Martiny. "We were able to fill in this gap through fieldwork and advanced analytical techniques. The outcome is the first comprehensive in situ quantification of nutrient uptake capabilities among dominant phytoplankton groups in the North Atlantic Ocean that takes into account microbial biodiversity."

Avoiding ecosystem collapse: Experts Weigh in

Avoiding ecosystem collapse: Experts Weigh in | Farming, Forests, Water & Fishing (No Petroleum Added) | Scoop.it
From coral reefs to prairie grasslands, some of the world's most iconic habitats are susceptible to sudden collapse due to seemingly minor events. A classic example: the decimation of kelp forests when a decline of otter predation unleashes urchin population explosions. Three studies hold the promise of helping resource managers predict, avoid, and reverse the tipping points that lead to degraded habitats, economic losses, and social upheaval.

...............  The islands look and work like wetlands. Man-made structures hold together their vegetation; the pollutant-sucking process works naturally. Roots suspended beneath the islands promote the growth of aquatic biofilm (the green slime you find on rocks) that “cleanse[s] the water through the breakdown, sorption, and metabolic transformation of nutrients and impurities,” explains the Biomatrix website.

 

Treatment plants have used biofilm filters for decades, reports Fast Company. But the company’s engineering additions, such as columns of synthetic fiber, maximize the growth of the beneficial bacteria that absorbs pollutants.

“Some progress has been made, but we haven’t yet reached a turning point,” said Ma Jun, one of the country’s leading environmentalists. “For many factories, the cost of violating the rules is lower than the cost of compliance.”

 

Also unchanged is the persecution of Mr. Wu, 46, a scrappy, self-taught environmentalist who spent three years in jail on what he said were trumped-up fraud charges — punishment, he said, for his dogged campaign against the factory owners and their local government allies, whom he blames for despoiling the lake.

Since emerging from prison in 2010, Mr. Wu has continued his advocacy work, prompting a predictable response from the authorities. He is subjected to periods of confinement at his home in Zhoutie, a village on Lake Tai. His cellphone is monitored by the police and he is barred from traveling beyond Yixing, the township in eastern Jiangsu Province that includes Zhoutie.

Plainclothes police officers often accompany him on shopping excursions, and surveillance cameras line the narrow road to his home. Vengeful officials, he said, have even stymied his efforts to find a job by warning away would-be employers. “If it wasn’t for the garden in front of my house, I’d probably starve,” said Mr. Wu, a short, pudgy-faced man who often sounds like he is shouting, even when indoors.

But environmentalists say there is reason for hope. In April, the central government revised the nation’s environmental law for the first time since 1989, imposing steep fines on polluters and requiring companies to disclose pollution data. The regulations, which take effect in January, will also allow environmental groups to file public interest lawsuits against factories that break the law.

Mr. Ma, the environmentalist, said the new measures include important tools for cleaning up Lake Tai and other ailing bodies of water, but the key would be enforcement. “All it takes is the mayor or the head of a county saying, ‘You can’t touch this factory. It’s too important to the local economy,’ ” he said.

........

More than 1,400 fishermen in and around Mamirauá take part in the pirarucu management regime, hewing to quotas and tagging each fish they catch. Fishermen in 2013 took home an average of about $650 each from pirarucu fishing, a welcome sum in far-flung villages. Still, illegal pirarucu fishing flourishes in parts of the Amazon, lowering prices for the fish in street markets.

 

While fisheries experts are generally encouraged by projects that have recovered badly overexploited pirarucu populations in some pockets of the rain forest, the illicit trade, especially in the neighboring state of Pará, has caused the megafish to disappear near large cities while threatening its survival in some forest settlements.

“We’re hoping the pirarucu can withstand such challenges, since a die-off would rob villages across the Amazon of their lifeblood,” said Claudio Batalha, 47, a coordinator of the fishing project here. “Without making such fishing sustainable, more outsiders could claim the forest as their own,” he added. “That’s when the threat of greater forest devastation gets real.”

Much of the change in climate change is happening to the ocean. It’s not just the extra heat hiding within the waves. The seven seas also absorb a big share of the carbon dioxide released by burning the fossilized sunshine known as coal, natural gas and oil. All those billions and billions of CO2 molecules interact with the brine to make it ever so slightly more acidic over time and, as more and more CO2 gets absorbed, the oceans become more acidic.

Tourism is the essential ingredient for all his plans, but tourists themselves are still in short supply, with Zimbabwe’s international reputation as a destination only just starting to recover. Some individuals, however, have made a huge impact: one holidaying Spanish dentist returned with a full surgical team and gave the area its first ever access to dental hygiene. Mark Butcher is hugely proud of that achievement, but he doesn’t lose sight of the greatest benefit a tourist can bring, merely their presence.

 

“Poachers don’t like to be seen,” he says. “This is the frontline where the war is being fought and tourists who get here are like eyes and ears against the enemy.”
