Chinese Kennel Owner Caught Stealing Electricity to Power Underground Bitcoin Mining Farm

Posted by in categories: bitcoin, business, food, sustainability

The largest oil field in the People’s Republic of China has been a target for individuals and organizations attempting to mine bitcoins with free electricity. After a bunch of mining farm operators allegedly got caught last summer, a dog kennel owner was recently busted for running cable lines in order to siphon free electricity from China’s Daqing Oil Field. The mining farm owner was arrested, as police found 54 ASIC miners stored in an underground bunker with dog kennels on top making it seem like a legitimate operation.

Electrical costs in China are cheaper than most places around the world, and that is why there is a high concentration of China-based bitcoin mining operations. To this day, it is estimated that more than 60% of today’s bitcoin miners operate in China. On April 26, the regional publication dbw.cn/heilongjiang published a report that explained a bitcoin miner was just arrested for allegedly stealing free electricity from the Daqing Oil Field. The report notes that the mining farm operator got away with the free electricity for months in order to power 54 mining rigs underground.

Further investigation shows that the mining farm owner also operated a K-9 kennel housed with dogs above the bunker. The cover made it seem like he was operating a legitimate business, while he had long cables running into China’s largest oil field. The oil field in Daqing is located between the Songhua river and Nen River. Estimates show that Daqing Oil Field has produced well over 10 billion barrels since the operation started. The man who was busted running cable lines into the oil field is not the only entrepreneur who has tried that specific method. Daqing Oil Field has been a target for many bitcoin mining operators who have attempted to run cables into the plant.

Tesla improves on its ‘million-mile battery’ with less cobalt and higher energy density

Posted by in categories: energy, sustainability, transportation

Tesla has made even more battery improvements on its new ‘million-mile battery’ now with less cobalt, which could result in lower cost and even more energy density.

Last year, we were the first to report on Tesla’s battery research partner, Jeff Dahn and his team at Dalhousie University, unveiling the impressive results of tests on a new battery cell that could last over 1 million miles in an electric vehicle.

Tesla Cybertruck gets turned into electric military vehicle in crazy renders

Posted by in categories: Elon Musk, military, sustainability

The military has been talking about incorporating electric vehicles in their fleet and with the Tesla Cybertruck being described as an “armored personnel carrier from the future”, a rendering artist decided to explore what a Cybertruck would look like as an electric Joint Light Tactical Vehicle.

As we reported last week, the military is developing a plan to use EVs for remote missions and even cited Tesla as an example that larger EVs are viable.

How a mycologist is making ‘living’ bricks out of mushrooms that are stronger than concrete

Posted by in categories: materials, sustainability

Circa 2017 o.,o.

Philip Ross is an artist and lecturer at Stanford University who focuses on an unlikely sustainable design element: mushrooms. After years of growing mushrooms, Ross has learned that there’s far more than meets the eye to mycelium — the extensive and tangled network of rootlike fibers that grow beneath the ground. According to our fungus expert, when left to dry the mycelium can become an excellent raw material for various constructions. For instance, Ross used the mycelium to fashion bricks out of.

Among its many properties, the mycelium bricks are:

America’s renewable energy sources have produced more electricity than coal every day for 40 days straight

Posted by in categories: economics, energy, finance, sustainability

Renewable sources including solar, wind and hydropower generated more electricity than coal-based plants every single day in April, a new report says.

Analysis shared by the Institute for Energy Economics and Financial Analysis (IEFA), based on data from the U.S. Energy Information Administration (EIA), said the finding marks a major “milestone” in an energy transition that is now underway.

Visualising algae-eating viruses from space

Posted by in categories: biological, climatology, sustainability

Algae isn’t just found in your garden pond or local river. Sometimes it explodes into vast “blooms” far out to sea, that can be the size of a small country. Such algal blooms can match even a rainforest at taking carbon out of the air. And then, in just a week or two, they are gone – sometimes consumed by viruses.

Given the scale of blooms and their vital role in both marine ecology and climate regulation we must know more about these viruses. Research conducted with our Weizmann Institute colleague Yoav Lehahn and others and published in the journal Current Biology, is the first attempt to quantify the affect of viruses on large scale algal blooms.

Algae in this context refers to tiny sea organisms known as phytoplankton which exist right at the bottom of the marine food web, providing the ultimate source of all organic matter in the sea. They do this by consuming carbon dioxide during photosynthesis, “fixing” this carbon into organic matter (themselves) in the same way trees take carbon out of the air.

Study reveals single-step strategy for recycling used nuclear fuel

Posted by in categories: chemistry, engineering, nuclear energy, sustainability

A typical nuclear reactor uses only a small fraction of its fuel rod to produce power before the energy-generating reaction naturally terminates. What is left behind is an assortment of radioactive elements, including unused fuel, that are disposed of as nuclear waste in the United States. Although certain elements recycled from waste can be used for powering newer generations of nuclear reactors, extracting leftover fuel in a way that prevents possible misuse is an ongoing challenge.

Now, Texas A&M University engineering researchers have devised a simple, proliferation-resistant approach for separating out different components of . The one-step chemical reaction, described in the February issue of the journal Industrial & Engineering Chemistry Research, results in the formation of crystals containing all of the leftover nuclear elements distributed uniformly.

The researchers also noted that the simplicity of their recycling approach makes the translation from lab bench to industry feasible.

This Solar Panel-Like Device Can Generate Electricity in the Dark

Posted by in categories: solar power, sustainability

But a new invention could allow us to continue generating renewable energy even in the dark, the New York Times reports. Electrical engineer Aaswath Raman, at the University of California in LA, has come up with a device that can harness energy from a dark night sky to power an LED — hinting at a new frontier in renewable energy.

Power of the Dark Side

Raman’s findings were published in the journal Joule today. His device — made from easy-to-find materials including Styrofoam and off-the-shelf aluminum parts — takes advantage of radiative cooling, the process that allows objects to release heat after the Sun sets.
