Wow! NASA photographer spots space station crossing the sun during spacewalk (video)

Posted by in categories: energy, space

The mosaic image is a composition of seven subsequent frames taken from Nellysford, Virginia, as the space station traversed the face of the sun at the speed of roughly 5 miles per second, which is about 18000 mph (29000 kph), according to a NASA photo description.

The six-hour and 45-minute spacewalk was the third for Pesquet and Kimbrough in less than two weeks as they completed work on augmenting the space station’s power systems. The iROSA panel deployed on Friday was the second of six new panels to be installed at the station.

Friday’s extravehicular activity (EVA) positioned the second iROSA opposite the first on the far left, or port side of the space station’s backbone truss. Now both the 2B and 4B power channels on the port 6 (P6) truss have the new arrays deployed.

Railroads To Pour Cold Renewable Energy Water On Koch Industries

Posted by in categories: business, chemistry, energy, sustainability, transportation

The US power grid needs all of support it can get. Sad that some would stand in the way of progress.


There is no love lost between the notorious Koch brothers and the nation’s railroad industry, and the relationship is about to get a lot unlovelier. A massive new, first-of-its-kind renewable energy transmission line is taking shape in the Midwest, which will cut into the Koch family’s fossil energy business. It has a good chance of succeeding where others have stalled, because it will bury the cables under existing rights-of-way using railroad rights-of-way and avoid stirring up the kind of opposition faced by conventional above-ground lines.

The Koch brothers and their family-owned company, Koch Industries, have earned a reputation for attempting to throttle the nation’s renewable energy sector. That makes sense, considering that the diversified, multinational firm owns thousands of miles of oil, gas, and chemical pipelines criss-crossing the US (and sometimes breaking down) in addition to other major operations that depend on rail and highway infrastructure.

China turns on world’s second-biggest hydropower dam

Posted by in categories: energy, government

Plans call for the 289-meter-tall (954-foot-tall) Baihetan Dam to have 16 generating units with a capacity of 1 million kilowatts each. That will make it second in size after the Three Gorges Dam, opened in 2003 on the Yangtze, with 22.5 million kilowatts of generating capacity.


BEIJING (AP) — The first two generating units of the world’s second-biggest hydroelectric dam were officially turned on Monday in southwestern China, the government announced.

The Baihetan Dam on the Jinsha River, a tributary of the Yangtze, is part of Chinese efforts to curb surging fossil fuel demand by building more hydropower capacity at a time when dams have fallen out of favor in other countries due to environmental complaints.

Rare Superconductor Discovered – May Be Critical for the Future of Quantum Computing

Posted by in categories: energy, quantum physics, supercomputing

Research led by Kent and the STFC Rutherford Appleton Laboratory has resulted in the discovery of a new rare topological superconductor, LaPt3P. This discovery may be of huge importance to the future operations of quantum computers.

Superconductors are vital materials able to conduct electricity without any resistance when cooled below a certain temperature, making them highly desirable in a society needing to reduce its energy consumption.

They manifest quantum properties on the scale of everyday objects, making them highly attractive candidates for building computers that use quantum physics to store data and perform computing operations, and can vastly outperform even the best supercomputers in certain tasks. As a result, there is an increasing demand from leading tech companies like Google, IBM and Microsoft to make quantum computers on an industrial scale using superconductors.

Ultraviolet LEDs prove effective in eliminating coronavirus from surfaces and, potentially, air and water

Posted by in categories: biotech/medical, energy

😃


As COVID-19 continues to ravage global populations, the world is singularly focused on finding ways to battle the novel coronavirus. That includes the UC Santa Barbara’s Solid State Lighting & Energy Electronics Center (SSLEEC) and member companies. Researchers there are developing ultraviolet LEDs that have the ability to decontaminate surfaces — and potentially air and water — that have come in contact with the SARS-CoV-2 virus.

“One major application is in medical situations — the disinfection of personal protective equipment, surfaces, floors, within the HVAC systems, et cetera,” said materials doctoral researcher Christian Zollner, whose work centers on advancing deep ultraviolet light LED technology for sanitation and purification purposes. He added that a small market already exists for UV-C disinfection products in medical contexts.

Indeed, much attention of late has turned to the power of ultraviolet light to inactivate the novel coronavirus. As a technology, ultraviolet light disinfection has been around for a while. And while practical, large-scale efficacy against the spread of SARS-CoV-2 has yet to be shown. UV light shows a lot of promise: SSLEEC member company Seoul Semiconductor in early April reported a “99.9% sterilization of coronavirus (COVID-19) in 30 seconds” with their UV LED products. Their technology currently is being adopted for automotive use, in UV LED lamps that sterilize the interior of unoccupied vehicles.

This alien-like metal may one day power your electronics

Posted by in categories: electronics, energy

Bismuth has been around for thousands of years, yet it’s only been used in a handful of applications — and mostly to treat stomach ailments. But as the world looks for cleaner and safer energy, bismuth might soon become the star of the heavy metals family.

Solar storms are back, threatening life as we know it on Earth

Posted by in categories: energy, satellites

A few days ago, millions of tons of super-heated gas shot off from the surface of the sun and hurtled 90 million miles toward Earth.

The eruption, called a coronal mass ejection, wasn’t particularly powerful on the space-weather scale, but when it hit the Earth’s magnetic field it triggered the strongest geomagnetic seen for years. There wasn’t much disruption this time—few people probably even knew it happened—but it served as a reminder the sun has woken from a yearslong slumber.

While invisible and harmless to anyone on the Earth’s surface, the geomagnetic waves unleashed by solar storms can cripple , jam radio communications, bathe airline crews in dangerous levels of radiation and knock critical satellites off kilter. The sun began a new 11-year cycle last year and as it reaches its peak in 2025 the specter of powerful space weather creating havoc for humans grows, threatening chaos in a world that has become ever more reliant on technology since the last big storms hit 17 years ago. A recent study suggested hardening the grid could lead to $27 billion worth of benefits to the U.S. power industry.

Quantum Breakthrough: New Invention Keeps Qubits of Light Stable at Room Temperature

Posted by in categories: encryption, energy, quantum physics

Researchers from University of Copenhagen have developed a new technique that keeps quantum bits of light stable at room temperature instead of only working at-270 degrees. Their discovery saves power and money and is a breakthrough in quantum research.

As almost all our private information is digitalized, it is increasingly important that we find ways to protect our data and ourselves from being hacked.

Quantum Cryptography is the researchers’ answer to this problem, and more specifically a certain kind of qubit — consisting of single photons: particles of light.

Reaping the Benefits of Noise: Scientists Show 10x Efficiency Increase in Harvesting Energy From Noise

Posted by in categories: energy, media & arts, physics

Signals can be amplified by an optimum amount of noise, but this so-called stochastic resonance is a rather fragile phenomenon. Researchers at AMOLF were the first to investigate the role of memory for this phenomenon in an oil-filled optical microcavity. The effects of slow non-linearity (i.e. memory) on stochastic resonance were never considered before, but these experiments suggest that stochastic resonance becomes robust to variations in the signal frequency when systems have memory. This has implications in many fields of physics and energy technology. In particular, the scientists numerically show that introducing slow non-linearity in a mechanical oscillator harvesting energy from noise can increase its efficiency by tenfold. They published their findings in Physical Review Letters on May 27th.

It is not easy to concentrate on a difficult task when two people are having a loud discussion right next to you. However, complete silence is often not the best alternative. Whether it is some soft music, remote traffic noise or the hum of people chatting in the distance, for many people, an optimum amount of noise enables them to concentrate better. “This is the human equivalent of stochastic resonance,” says AMOLF group leader Said Rodriguez. “In our scientific labs stochastic resonance happens in non-linear systems that are bistable. This means that, for a given input, the output can switch between two possible values. When the input is a periodic signal, the response of a non-linear system can be amplified by an optimum amount of noise using the stochastic resonance condition.”
