This is like a Wizard who uses the magic mana to infuse his/her wands/objects with the magic power itself.

I would think "they" might have attempted this long ago.  I guess I was wrong and "we" all are still ignoring some common sense ideas.   :mellow:

Here's an attempt at common sense that Eye will attempt now.




Get rid of the silly base and star tracking system and fill  a third of this big bag of water at the bottom with solar cells.

This will in effect create a shallow  bowl/crater-shape that needs no tracking and is passive.
In effect it is a Water storage container that can also be a solar bowl or just a nice little cuppa sol. :coffee2:

Self-cooling solar cells boost power, last longer

Scientists may have overcome one of the major hurdles in developing high-efficiency, long-lasting solar cells—keeping them cool, even in the blistering heat of the noonday Sun.

Scientists may have overcome one of the major hurdles in developing high-efficiency, long-lasting solar cells—keeping them cool, even in the blistering heat of the noonday Sun.

Part of this loss is the unavoidable consequence of converting sunlight into electricity. A surprisingly vexing amount, however, is due to solar cells overheating.

Under normal operating conditions, solar cells can easily reach temperatures of 130 degrees Fahrenheit (55 degrees Celsius) or more. These harsh conditions quickly sap efficiency and can markedly shorten the lifespan of a solar cell. Actively cooling solar cells, however—either by ventilation or coolants—would be prohibitively expensive and at odds with the need to optimize exposure to the Sun.

The newly proposed design avoids these problems by taking a more elegant, passive approach to cooling. By embedding tiny pyramid- and cone-shaped structures on an incredibly thin layer of silica glass, the researchers found a way of redirecting unwanted heat—in the form of infrared radiation—from the surface of solar cells, through the atmosphere, and back into space.

"Our new approach can lower the operating temperature of solar cells passively, improving energy conversion efficiency significantly and increasing the life expectancy of solar cells," said Linxiao Zhu, a physicist at Stanford and lead author on the Optica paper. "These two benefits should enable the continued success and adoption of solar cell technology."

Solar cells work by directly converting the Sun's rays into electrical energy. As photons of light pass into the semiconductor regions of the solar cells, they knock off electrons from the atoms, allowing electricity to flow freely, creating a current. The most successful and widely used designs, silicon semiconductors, however, convert less than 30 percent of the energy they receive from the Sun into electricity – even at peak efficiency.

The solar energy that is not converted generates waste heat, which inexorably lessens a solar cell's performance. For every one-degree Celsius (1.8 degree F) increase in temperature, the efficiency of a solar cell declines by about half a percent.

"That decline is very significant," said Aaswath Raman, a postdoctoral scholar at Stanford and co-author on the paper. "The solar cell industry invests significant amounts of capital to generate improvements in efficiency. Our method of carefully altering the layers that cover and enclose the solar cell can improve the efficiency of any underlying solar cell. This makes the design particularly relevant and important."

In addition, solar cells "age" more rapidly when their temperatures increase, with the rate of aging doubling for every increase of 18 degrees Fahrenheit.

To passively cool the solar cells, allowing them to give off excess heat without spending energy doing so, requires exploiting the basic properties of light as well as a special infrared "window" through Earth's atmosphere.

Different wavelengths of light interact with solar cells in very different ways—with visible light being the most efficient at generating electricity while infrared is more efficient at carrying heat. Different wavelengths also bend and refract differently, depending on the type and shape of the material they pass through.

The researchers harnessed these basic principles to allow visible light to pass through the added silica layer unimpeded while enhancing the amount of energy that is able to be carried away from the solar cells at thermal wavelengths.

"Silica is transparent to visible light, but it is also possible to fine-tune how it bends and refracts light of very specific wavelengths," said Fan, who is the corresponding author on the Optica paper. "A carefully designed layer of silica would not degrade the performance of the solar cell but it would enhance radiation at the predetermined thermal wavelengths to send the solar cell's heat away more effectively."

To test their idea, the researchers compared two different silica covering designs: one a flat surface approximately 5 millimeters thick and the other a thinner layer covered with pyramids and micro-cones just a few microns (one-thousandth of a millimeter) thick in any dimension. The size of these features was essential. By precisely controlling the width and height of the pyramids and micro-cones, they could be tuned to refract and redirect only the unwanted infrared wavelengths away from the solar cell and back out into space.

"The goal was to lower the operating temperature of the solar cell while maintaining its solar absorption," said Fan. "We were quite pleased to see that while the flat layer of silica provided some passive cooling, the patterned layer of silica considerably outperforms the 5 mm-thick uniform silica design, and has nearly identical performance as the ideal scheme."

Zhu and his colleagues are currently fabricating these devices and performing experimental tests on their design. Their next step is to demonstrate radiative cooling of solar cells in an outdoor environment. "We think that this work addresses an important technological problem in the operation and optimization of solar cells," he concluded, "and thus has substantial commercialization potential."

Ben Fulford is very uneven in his sources,

That's putting it mildly. How do you procure nearly 300 bodies without anyone noticing their absence? How do you then explain the lack of resemblance to the official deceased when those bodies get to the alleged bereaved, particularly if DNA tests are done? Or are the families all stooges?
Too many hard-to-answer questions.

Where are the bodies from the "Missing" Malaysian flight with NO WRECKAGE !!!???

Or how about the missing bodies from the Planes that supposedly hit Shanksville PA and the Pentagon Lawn, not to mention the second plane to hit tower two at NYC ????   Also with NO WRECKAGE seen in a Harry Potter "portkey" aspirate away zone ??? 

C'mon the USA Bankster Gangsters have enough bodies on "ice" to do this again and again and again.

Jurors say they believe Tazhayakov got fair trial



Does convicting Tazhayakov  before  Dzjokhar  set precedence?


Will this legal precedence lend credence to an assumption of logic.

A Dzjokhar's joker's poker's liars club.


Does convicting Tazhayakov convict Dzjokhar?

 Dzjokhar should have been tried first.

What a shame of a sham.

What are You Trying to Hide, Mr Obama?
Quote
Despite Obama’s baseless disparagement of the self-defence militia as being «an insult to the international community», on the same day that he made that announcement the Malaysian Prime Minister Najib Razak was praising the local authorities for having made arrangements to retrieve the bodies and to hand over the vitally important black box recorders from the doomed airliner. The latter data could reveal what caused the passenger plane to explode in mid-air and crash.

Significantly, the Malaysian premier did not make the arrangements through the Kiev regime. He dealt directly with the Donetsk People’s Republic leader Alexander Borodai. The Malaysians disclosed publicly that 282 of the bodies recovered so far were to be transported in refrigerated train carriages to Donetsk and thence to the city of Kharkiv before being flown on to Amsterdam. The flight recorder black boxes were also to be handed over in Donetsk by militia members to an official Malaysian investigative team…

In the latest onslaught by Kiev forces in Donetsk it seems more than a coincidence that they have attacked the central train station in that city – from where the airline crash corpses were to be transported. Some rail tracks were reportedly damaged by shelling, thus putting transport of the human remains in jeopardy.

The Washington Post reported early Monday: «Michael Bociurkiw, an OSCE spokesman, said it remained unclear when the rail cars containing the bodies would move and where they would go. He said renewed fighting in Donetsk on Monday had possibly damaged the tracks, adding a complication.

«We were told by rebels it has caused some damage to the railway system,» said the OSCE spokesman. «That is a crucial development in the sense that with the airport inoperable, and if the train station is inoperable, that will cut off Donetsk even further».

The OSCE team confirmed to media on Saturday – less than 48 hours after the airliner was downed – that they had gained full access to the crash site, facilitated by the local self-defence militia, even though Kiev forces were conducting intimidating flyovers with warplanes.

Meanwhile, Dutch investigators who oversaw the eventual placement of the 282 corpses into a train at the town of Torez, near the crash site, for transport on to Donetsk, spoke admirably of the local rescue teams that the self-defence militia and community had organized.

Reuters reported: «Peter van Vliet, whose team went through the wagons dressed in surgical masks and rubber gloves, said he was impressed by the work the recovery crews had done, given the heat and the scale of the crash site». Vliet told Reuters: «I think they did a hell of a job in a hell of a place».

And so the Dutch investigators should be in admiration. The people of Donetsk are trying to rescue victims in conditions of extreme duress imposed by Kiev’s terrorist operations.

All the while, Russian President Vladimir Putin has been calling for a ceasefire from the Kiev forces so that a full and safe international investigation can take place into what happened Flight MH17. On Monday, Putin called for the disaster not to be politicised by narrow self interests.

So far, Putin’s appeal for safe passage for investigators has been wilfully ignored by the Kiev regime, which has if anything stepped up its violence in the region since the air crash.

And Western leaders are giving full cover to the Kiev regime by perversely laying the blame on Russia and the self-defence militias in Donetsk, accusing both of obstructing recovery and a crash probe.

To paraphrase Obama: «What is the Kiev regime and its Western sponsors trying to hide?»

As for Australia’s premier Abbott, what seems to be getting up his nose is the fact that the Western-backed criminals in Kiev are not in charge of the crime scene.

Penny for your thoughts
Truth exists; only lies are invented.
Tuesday, July 22, 2014

The US backs off it's false flag! "No direct link to Russia in downing of MH17

No direct link to Russia in downing of Flight MH17: U.S. officials

 The intelligence officials were cautious in their assessment, noting that while the Russians have been arming separatists in eastern Ukraine,(yet another claim made by the US that has never been proven)  the U.S. had no direct evidence that the missile used to shoot down the passenger jet came from Russia"
I am going to ignore all the wild speculation these mouthpieces engaged in and cut to the chase!
In big bold lettering because I want this easily readable to all

"the officials said they did not know who fired the missile"

"In terms of who fired the missile, "we don't know a name, we don't know a rank and we're not even 100 per cent sure of a nationality"

 "The officials made clear they were relying in part on social media postings and videos made public in recent days by the Ukrainian government, even though they have not been able to authenticate all of it"

 Have they authenticated any of it?

 For example, they cited a video of a missile launcher said to have been crossing the Russian border after the launch, appearing to be missing a missile.

  But later, under questioning, the officials acknowledged they had not yet verified that the video was exactly what it purported to be.

  The missile launcher that US intelligence had claimed crossed the Russian border was shown in the video presentation by Russia

 If the US is acknowledging they have no evidence of a SAM being fired. The question that begs asking is....
Did the Ukrainian military plane, that was mysteriously flying in the vicinity of MH-17, fire at the passenger plane bringing it down?

*Because what this admission all boils down to is that nothing the US has previously claimed as fact can be verified as truth, fact or even correct!*

 And finally, from the linked news article. Last paragraph!

"On Monday, President Barack Obama said (directly quoted)  the Malaysia Airlines plane "was shot down over territory controlled by Russian-backed separatists in Ukraine." He also said Russia has both trained the separatists and "armed them with military equipment and weapons, including anti-aircraft weapons."

Obama LIED.  He LIED.  Many people died for these lies.

 I will embed the Russian presentation below. I will also include one from the US representative.
