A New Solar Cell Converts The Sun’s Heat Into Usable Energy

Stephan:  Yet another breakthrough in the raging momentum that is the solar technology trend.

The sun gives us so much, providing both lighting and heating for our planet. We try to take advantage of this constant stream of power by using solar panels to convert light into electrical energy. It’s a bright idea. But, could we be harnessing more of the sun?

Researchers at MIT think so. In a paper published this week in Nature Energy researchers describe building a working solar thermophotovoltaic device, or STPV. The STPV solar cell has a layer that absorbs heat and light from sunlight and reflects it back out as light, which is then captured by a nearby solar cell and turned into power. The light emitted by the device is calibrated to be the perfect wavelength for the solar cell, making it function at peak efficiency. Normally, a solar cell or photovoltaic device just convert light into electricity without going through the intermediate step with heat.

Heat is energy that is constantly wasted, just dispersing […]

Obama plans to reveal massive cache of UFO secrets before leaving office: report

Stephan:  People have been talking about the government's secret UFO documents, Area 51, the whole nine yards for decades. Particularly since Roswell. Well the big data dump is coming, thanks to President Obama. Hard to know how the conspiracy people will take this -- they didn't reveal everything probably -- but however it plays out it is going to be fascinating to watch.

President Barack Obama joked with Jimmy Kimmel about aliens and UFOs in his last appearance on the show, but now it seems the Obama administration may release more information before leaving office.

Steve Bassett, executive director of the Paradigm Research Group, told Daily Express that he has been lobbying the White House for 20 years in an attempt to get information surrounding UFOs declassified.

“This will be a reality this year and across the front pages of newspapers across the world,” he said. “The most significant news story that has ever been broken.”

Ahead of the premiere of the six-episode season of The X-Files, the CIA declassified dozens of photos and hundreds of pages of reports on UFOs dating back to the 1950s. But it’s comments from a top campaign official to Democratic presidential candidate Hillary Clinton that has Bassett excited. Clinton has promised that if she is elected, her administration will release the information.

Clinton’s senior campaign official is John Podesta  also served as a […]

Tribes Create Their Own Food Laws to Stop USDA From Killing Native Food Economies

Stephan:  Here is some good news about food. One of the interesting trends I have been following, which is getting almost no attention is that there has been a transition in the American Indian tribes. Younger tribal members are better educated, some have become lawyers. The fact that Native America groups are, under sovereign treaties, in many ways independent nations has not eluded these millennials, who are sophisticated enough to understand the leverage this gives. Also, at least in the Pacific Northwest the tribes beginning about a year and a half ago decided to form a council so they can speak with the collective voice. Thanks to the Lummi Tribe the ill-conceived coal port in Cherry Point, Washington was blocked. These 19th century treaties were drafted at a time when the goal of the dominant White culture was that the tribes would either be assimilated, like the Poles and Italians, or put on worthless land no one else wanted and left to more or less fend with themselves with just enough basic support to reduce problems.  The United States committed itself through those treaties and they are very vaguely word because no in Washington thought they meant much. That vague wording is being put to good use, and it is wonderful to watch. Here's an example.

SALT RIVER PIMA-MARICOPA INDIAN COMMUNITY, Ariz. – Jacob Butler eyed a lemon tree—its bright yellow fruit nestled among thick green leaves and set against the blue Arizona sky—then checked on the tiny pomegranates and grapes in the garden as a black-striped lizard darted into the shade of a mesquite tree. In the distance, downtown Phoenix glittered under the rising sun.

”Our garden is a platform to perpetuate our culture.“

“We try to grow what’s been here for hundreds, if not thousands, of years,” says Butler, the Salt River Pima-Maricopa Indian Community garden coordinator, as he surveyed the land and the plants growing on it. “For the past 13 years we’ve been doing this, so it’s in the minds of the people now.”

Traditionally, Pima and Maricopa tribal members grew lima beans, squash, corn, and other vegetables; used mesquite trees […]

A Shocking Find In a Neanderthal Cave In France

Stephan:  Yet another door into the ancient past opens and everything we thought we knew about Neanderthals must be discarded. I think this is extraordinarily exciting research

In February 1990, thanks to a 15-year-old boy named Bruno Kowalsczewski, footsteps echoed through the chambers of Bruniquel Cave for the first time in tens of thousands of years.

The cave sits in France’s scenic Aveyron Valley, but its entrance had long been sealed by an ancient rockslide. Kowalsczewski’s father had detected faint wisps of air emerging from the scree, and the boy spent three years clearing away the rubble. He eventually dug out a tight, thirty-meter-long passage that the thinnest members of the local caving club could squeeze through. They found themselves in a large, roomy corridor. There were animal bones and signs of bear activity, but nothing recent. The floor was pockmarked with pools of water. The walls were punctuated by stalactites (the ones that hang down) and stalagmites (the ones that stick up).

Some 336 meters into the cave, the caver stumbled across […]

Ancient Beer Recipe Uncovered in China, Archaeologists Say

Stephan:  Here is another door opening, beer making in China 5,000 years ago. And good beer at that. We make a grave mistake when we assume that ancient peoples were stupid or unskilled. As the report describes these ancient Chinese used the same techniques used today. Note also the long range trade aspect of this story.

A beer recipe roughly 5,000 years old has been uncovered in China — and researchers call the finding “surprising” because it means people there were importing a critical ingredient from thousands of miles away.

A team of archaeologists from Stanford University, Brigham Young University and two Chinese institutions discovered a cache of ancient brewing equipment — including jugs, pots and funnels — containing remnants of mashed grains and other starches.

The researchers, who were working at the Mijiaya dig site, say their analysis reveals “a surprising beer recipe” containing a grain called broomcorn millet (Panicum miliaceum), barley (Hordeum vulgare), another grain called Job’s tears or Chinese pearl barley (Coix lacrymajobi), and some sort of tuber.

The “recipe” they compiled came from the analysis of those grain residues on the interiors of the vessels. Scholars say the evidence points to a culture that understood advanced brewing techniques that are very similar to modern methods.

“All indications are that ancient peoples, including those at Mijiaya, applied the same principles and techniques as brewers do today,” said Patrick McGovern, an archaeologist at the University of Pennsylvania, who was not involved with the research.

The earliest references to beer in Chinese literature do not pop up until […]
