Wow. First raptors getting slaughtered by wind turbines, now "streamers" from solar.
Alternative energy may prove to be worse than conventional energy on the environment as a whole.

Emerging solar plants scorch birds in mid-air
Aug 18, 12:42 AM (ET)

By ELLEN KNICKMEYER and JOHN LOCHER

IVANPAH DRY LAKE, Calif. (AP) — Workers at a state-of-the-art solar plant in the Mojave Desert have a name for birds that fly through the plant's concentrated sun rays — "streamers," for the smoke plume that comes from birds that ignite in midair

Federal wildlife investigators who visited the BrightSource Energy plant last year and watched as birds burned and fell, reporting an average of one "streamer" every two minutes, are urging California officials to halt the operator's application to build a still-bigger version.

The investigators want the halt until the full extent of the deaths can be assessed. Estimates per year now range from a low of about a thousand by BrightSource to 28,000 by an expert for the Center for Biological Diversity environmental group.

The deaths are "alarming. It's hard to say whether that's the location or the technology," said Garry George, renewable-energy director for the California chapter of the Audubon Society. "There needs to be some caution."

The bird kills mark the latest instance in which the quest for clean energy sometimes has inadvertent environmental harm. Solar farms have been criticized for their impacts on desert tortoises, and wind farms have killed birds, including numerous raptors.

"We take this issue very seriously," said Jeff Holland, a spokesman for NRG Solar of Carlsbad, California, the second of the three companies behind the plant. The third, Google, deferred comment to its partners.

The $2.2 billion plant, which launched in February, is at Ivanpah Dry Lake near the California-Nevada border. The operator says it is the world's biggest plant to employ so-called power towers.

More than 300,000 mirrors, each the size of a garage door, reflect solar rays onto three boiler towers each looming up to 40 stories high. The water inside is heated to produce steam, which turns turbines that generate enough electricity for 140,000 homes.

Sun rays sent up by the field of mirrors are bright enough to dazzle pilots flying in and out of Las Vegas and Los Angeles.

Federal wildlife officials said Ivanpah might act as a "mega-trap" for wildlife, with the bright light of the plant attracting insects, which in turn attract insect-eating birds that fly to their death in the intensely focused light rays.

Federal and state biologists call the number of deaths significant, based on sightings of birds getting singed and falling, and on retrieval of carcasses with feathers charred too severely for flight.

Ivanpah officials dispute the source of the so-called streamers, saying at least some of the puffs of smoke mark insects and bits of airborne trash being ignited by the solar rays.

Wildlife officials who witnessed the phenomena say many of the clouds of smoke were too big to come from anything but a bird, and they add that they saw "birds entering the solar flux and igniting, consequently become a streamer."

U.S. Fish and Wildlife officials say they want a death toll for a full year of operation.

New invisibility cloak device can hide almost anything

By David Nield·Published September 29, 2014

“People have been fascinated with cloaking for a very long time,” said John Howell, a Professor of Physics at the University. “It’s recently been a really popular thing in science fiction and Harry Potter… I think people are really excited about the prospect of just being invisible.”

“From what we know this is the first cloaking device that provides three-dimensional, continuously multidirectional cloaking,” said doctoral student Joseph Choi, one of the team who worked on the project, when speaking to Reuters. “I imagine this could be used to cloak a trailer on the back of a semi-truck so the driver can see directly behind him. It can be used for surgery, in the military, in interior design, art.”

What makes this system so interesting is that it’s simple, inexpensive and capable of working at multiple angles, as long as the object remains inside the series of lenses. Howell and Choi say it cost them $1,000 to get all of the necessary equipment together, but it can be done more cheaply. A patent is pending for their invention but the pair have put together instructions on making your own Rochester Cloak at home for less than $100.

Interesting idea - except you made it out of aluminalzheimers.



Flare pans: A faster, greener way to boil liquids

Dr. Thomas Povey, an Oxford engineering professor, invented the Flare pan, cookware that is 40 percent more energy efficient than regular pans.

By Emily Scott - Tech Page One Aug 12 2014



Dr. Thomas Povey, an Oxford professor who spends most of his time building jet engines, invented a pan that boils liquids faster and saves 40 percent more energy than ordinary cookware.

Povey came up with the idea for Flare pans while on a camping trip, where the high altitudes made boiling a pot of water take longer than usual. The engineering professor thought about how the pan’s design prevented it from boiling water efficiently.
Povey and a team of Oxford students spent three years perfecting the invention, which has a cast-aluminum body and stainless steel handle. Shortly after, the invention made its debut online.
How Flare pans work

“We used a combination of thermocouples (temperature-measuring devices) and infrared camera images to measure the efficiency of the pan, and we did back-to-back tests against conventional pans,” Povey said in a
, the United Kingdom’s leading kitchenware company.
With conventional pans, a significant amount of heat disperses into the air, causing energy to be lost. But the Flare pan uses technology that is often found in jet engines. Fins on the sides of the pan capture heat that would otherwise be lost. This is known as FIN-X technology and helps distribute heat evenly. This technology allows for heat transfer to happen quicker without using as much energy.
First designed for outdoor use during camping trips, the Flare pan could also be suitable for indoor cooking, Povey discovered.
“We realized it was a problem that applies to the domestic market,” he told the Telegraph. “So we worked from there.”
How the device got off the ground

The pans were developed through Isis Innovation, Oxford’s research and technology commercialization branch. Povey and Isis approached the Design Council, a British government-established charity that helps people and businesses understand design and use it effectively.
The team from Oxford went through a program of support, which is created to meet the needs of public and private sector organizations seeking to develop and innovate their products and services, including technology research — even for large businesses. The Design Council uses design thinking to identify where design can best encourage growth.
The Flare pan has received attention from the press for being innovative and won the 2014 Hawley Award from the Worshipful Company of Engineers for “the most outstanding engineering innovation that delivers demonstrable benefit to the environment.”
John Loughhead, executive director of UK Energy Research Centre and chairman for the Hawley Award, told Tech Page One why the Flare Pan won the award.
“That particular one [innovation] was chosen because it offers a substantial reduction in the energy used in boiling pans during cooking, and that’s quite a big consumer of energy in the UK,” Loughhead said.
The cookware is available through the Lakeland website and starts at $85. Shipping is slated to begin Aug. 25 in the United Kingdom.
What’s remarkable about the pan is its basic principles of heat transfer can be applied to various appliances, including woks, pressure cookers and kettles. It can also be applied outside of the kitchen to objects that require open flames, such as water heating or melting asphalt for road surfacing.
“It’s very rapidly gone from a piece of engineering development to the marketplace,” Loughhead said.

>Overnight, a thruster on the lander failed to respond to commands sent from Earth. Engineers tried for hours to correct the fault but to no avail. The malfunction threatened to abort the mission, but at 0235 GMT on Wednesday mission controllers decided to go ahead with the landing regardless.

The nitrogen thruster, facing upwards from the top of the lander, was designed to fire for 60 seconds as Philae touched down to prevent it from bouncing off the comet’s surface where the gravitational pull is several hundred thousand times weaker than on Earth.

>After a historic but awkward comet landing, the robot probe Philae is now stable and sending pictures - but there are concerns about its battery life.

The lander bounced twice, initially about 1km back out into space, before settling in the shadow of a cliff, 1km from its intended target site.

It may now be problematic to get enough sunlight to charge its battery systems.

>Esa scientists described the lander as “stable” on Thursday morning despite concerns following the touchdown on Wednesday afternoon. It emerged that a harpoon which was meant to tether it to the surface of the 2.5 mile-wide comet had failed to deploy.

Pictures taken by Philae of its surroundings show it pressed up against what appears to be a hard wall of some kind.

Telemetry indicates it is on a slope or perhaps even on its side.

Certainly, one of its three feet is not in contact with the surface.

>The key issue vexing controllers right now is the lighting conditions.

Philae is receiving about 1.5 hours of illumination during every 12-hour rotation of the comet.

This will be insufficient to top up its battery system once the primary charge it had on leaving Rosetta runs out. That was some 60-plus hours.

It means Philae is unlikely to be operating in its present state beyond Saturday.

Wonder what other viruses can be "filtered out"?
Exerpts:
Patient cured of Ebola in Germany treated with biofiltration device

By Alexandria Hein
Published November 14, 2014

A Ugandan man hospitalized in Germany for the Ebola virus was treated with a biofiltration device that the creators believe will change the landscape in the fight against viral pathogens.

The Aethlon Medical team has created a device called the Hemopurifier, which works on the established infrastructure of dialysis machines already located in hospitals and clinics.

“It works within a dialysis machine, but the mechanism selectively targets viral pathogens and immunosuppressive toxins that they release,” James Joyce, the CEO of Aethlon Medical, told FoxNews.com.

The Hemopurifier is an extracorporeal biofiltration device that converges hollow-fiber filtration technology with immobilized affinity agents to allow for the rapid physical removal of virus and soluble viral glycoproteins from the blood. It mimics the natural immune system response for clearance of circulating virus and viral toxins before cells and organs can be infected, according to Joyce.

“Our goal is to eliminate the circulating viruses and do it on a rapid basis,” Joyce said. “The virus that we capture then remains in the [device’s] cartridge,” he said.

Doctors at University Hospital Frankfurt had been following the clinical trials and the device’s technology and reached out to Joyce’s team.

The physicians measured data points related to the treatment. The patient was monitored for changes in viral load, with the hope being for a reduction. Before treatment, the viral load was measured at 400,000 copies per milliliter for the Ebola virus. At the end of treatment physicians measured a reduction to only 1,000 copies per milliliter for Ebola.

The patient is now free of the virus.

To attempt to find evidence that a comet from the aftermath of the Big Bang created life on earth, not God. Of course that still leaves science scratching its head as to where the comet came from.

(Yet the lander has the Rosetta Disk which includes Gen 1-3... )

I wonder how the European taxpayers felt about it. Oh wait, they've learned not to question their governments. Their governments know best.

Philae comet lander sends more data before losing power

The little probe delivered everything expected from it, just as its failing battery dropped it into standby mode.

Philae is pressed up against a cliff. Deep shadows mean it cannot now get enough light on to its solar panels to recharge its systems.

The European Space Agency (Esa) fears this contact may have been the robot's last - certainly for a while.

A tweet from the official Philae lander account said: "I'll tell you more about my new home, comet 67P soon… zzzzz."

This sounds so much better than 'high speed rail'.


LA To San Fran In 35 Minutes? Hyperloop CEO Says Speed Tube Could Become Reality

December 17, 2014

PLAYA VISTA (CBSLA.com) — It takes about six hours to drive from Los Angeles to San Francisco – depending on your speed – and more than an hour to fly.

But in the future, the trip may take a matter of minutes.

Designers of the speed tube called Hyperloop say they are one step closer to making that happen.

Tesla founder Elon Musk says the technology is being developed with the help of about 25 UCLA graduate architecture students at a facility in Playa Vista.

Hyperloop has teamed up with the students to create the tube technology, designed to connect cities less than 300 miles apart.

“They look at this like a blank sheet of paper on which they can realize their fantasies,” UCLA professor Craig Hodgetts said.

On top of pylons is a hovering capsule inside a low-pressurized tube, which can reach speeds of up to 760 mph.

“The only resistance would be the air in front of the capsule, which we moved to the back by using a compressor,” Hyperloop CEO Dirk Ahlborn said.

A trip from L.A. to San Francisco would only take about 35 minutes. And because it is strictly run on solar power, developers say a ride would cost passengers about $30.

Students from around the world working on the project now have stock options in the company.

Ahlborn says within about 10 years and with about $16 billion Hyperloop could become a reality.

“It could be very easily put together. It’s more about thinking figuring out how to make it a good business,” he said.

Hyperloop is looking for people with different backgrounds to become involved with the project. For more information visit Hyperloop’s page at JumpStartFund.

The sun is such a trip!

Great article w/great pics:

Mystery at the sun's south pole: Nasa reveals huge 'coronal hole' on the solar surface where winds reach 500 miles per SECOND
>Coronal holes are regions of the corona where the magnetic field reaches out into space
>Particles moving along those magnetic fields can leave the sun rather than being trapped near the surface
>Polar coronal hole can remain visible for five years or longer, although constantly changes shape

Wait - what??

Who was in charge of checking the oil???


SpaceX is still poring over data from Saturday's attempt to land the rocket on a floating barge, the first test of its kind.

After the first stage of the Falcon rocket peeled away as planned following liftoff, it flew back to a giant platform floating off the Florida coast.

The guidance fins on the booster ran out of hydraulic fluid, however, right before touchdown, and it landed hard and broke into pieces.

The California company's billionaire founder, Elon Musk, was encouraged nonetheless and plans another rocket-landing test next month.
