Rawlemon’s Spherical Solar Energy-Generating Globes Can Even Harvest Energy from Moonlight

Rawlemon’s Spherical Solar Energy-Generating Globes Can Even Harvest Energy from Moonlight
The solar energy designers at Rawlemon have created a spherical, sun-tracking glass globe that is able to concentrate sunlight (and moonlight) up to 10,000 times. The company claims that its ß.torics system is 35% more efficient than traditional dual-axis photovoltaic designs, and the fully rotational, weatherproof sphere is even capable of harvesting electricity from moonlight.

The ß.torics system was invented by Barcelona-based German Architect André Broessel. He sought to create a solar system that could be embedded in the walls of buildings so that they may act as both windows and energy generators. But the project isn’t only noteworthy for its solar efficiency capabilities -  the ß.torics  system is designed to generate lunar energy too!

The spheres are able to concentrate diffused moonlight into a steady source of energy. The futuristic ß.torics system is catching a lot of attention for its clean and beautiful design. (Despite solar power’s huge potential, we haven’t seen too many beautiful solar power technologies). We’re excited to see how architects will incorporate these energy generating orbs into alternative energy agendas and future building designs!

WOW! Nasa's Hubble Telescope Presents 'Christmas Ornament' Festive Image  (Dialup Warning)

Observatories routinely release "holiday themed" heavenly photos come late December, and this time the Hubble Space Telescope bears good cheer for 2012 in the form of a cosmic Christmas ornament.

The Hubble photo depicts a planetary nebula that resembles a ribbon and glass bauble. While past holiday seasons have brought us a cosmic wreath, a nebula as snow-angel and an orb-like pulsar (spinning star) that resembles an ornament, this year's photo is a little more on the abstract side.

The central, circular shape of the nebula, called NGC 5189, can be seen as an ornament made of blown glass, and the reddish knotted structure that flows around the middle looks like a tangled ribbon that holds the ornament in place.

A planetary nebula is one of the last stages in the life of a mid-size star like our sun. The dying star sloughs off its outer layers and shoots them out into the universe, resulting in the "ribbon-like" filaments surrounding the middle of the star. At the center of the nebula is a densely packed white dwarf star whose mass is stuffed into a volume about the size of Earth, but the entire planetary nebula is the size of our solar system.

Connecticut Shootings: The Lessons From Dunblane, Scotland - Where 16 Children Were Massacred In '96

What happened on 13 March 1996 was the worst school shooting ever perpetrated in Britain. Sixteen children were killed - most of them just five years old. Their teacher was also shot.

= snip=

Out of the massacre came a determination that something should be done to prevent a similar horror in future.

There was the Snowdrop Campaign, calling for a ban on the private ownership and use of handguns in Britain. The campaign was named after the small spring flowers which had already begun to come out on that cold March morning. Some 700,000 people signed the Snowdrop petition and the law was changed.

There was legislation too, raising standards of school security across the UK. No longer would it be easy for an unauthorised adult to wander into a primary school gymnasium with four handguns and 700 rounds of ammunition, as Thomas Hamilton had done in Dunblane.

In Scotland, the link between the availability of guns and the number of people shot dead every year is accepted. Since Dunblane, the public have remained firmly in favour of keeping firearms out of private hands.

This year, five people have been killed by guns in Scotland. That's in line with the rest of the UK per head of population and a death rate 50 times lower than in the United States

Dunblane school massacre


Gun Control Network was founded in the aftermath of the shootings and was supported by some parents of victims at Dunblane and of the Hungerford Massacre.[12] Bereaved families and their friends also initiated a campaign to ban private gun ownership, named the Snowdrop Petition (because March is snowdrop time in Scotland), which gained 705,000 signatures in support and was supported by some newspapers, including the Sunday Mail, a Scottish newspaper whose own petition to ban handguns had raised 428,279 signatures within five weeks of the massacre.

The Cullen Inquiry into the massacre recommended that the government introduce tighter controls on handgun ownership[13] and consider whether an outright ban would be in the public interest.[14] The report also recommended changes in school security[15] and vetting of people working with children under 18.[16] The Home Affairs Select Committee agreed with the need for restrictions on gun ownership but stated that a handgun ban was not appropriate.

In response to this public debate, the then-current Conservative government introduced a ban on all cartridge ammunition handguns with the exception of .22 calibre single-shot weapons in England, Scotland and Wales. Following the 1997 General Election, the Labour government of Tony Blair introduced the Firearms (Amendment) (No. 2) Act 1997, banning the remaining .22 cartridge handguns in England, Scotland and Wales, and leaving only muzzle-loading and historic handguns legal, as well as certain sporting handguns (e.g. "Long-Arms" that fall outside the Home Office Definition of a "Handgun" due to their dimensions. The ban does not affect Northern Ireland, the Isle of Man, or the Channel Islands.

Secretary of State Al Gore?

1. Al Gore. I first heard this suggestion from my friend David Greenberg, the historian who writes for Slate, and I though, nahhh. But it grew on me pretty fast. Tell me why not. He'd be great. He's known around the world. He's respected around the world, about 90 percent of which surely wishes he'd been the president instead of the guy he beat. I'm not saying he'd change the world; no one can do that. But he'd get a hearing everywhere. He knows a huge number of world leaders, and he knows the issues cold. He could dive right into the pool's deepest end, in the Middle East, on Iran, you name it.

What about his climate-change crusade, you wonder? Far from having to drop his signature issue, Gore could use his new position to push it with even greater vigor in a global context. Gore, and probably Gore alone, would be capable of elevating the climate change issue to the position it deserves on the national and global stage.

What we don't know that much about is the Gore-Obama relationship. In 2007 and 2008, Gore clearly tilted toward Obama (Gore's mere refusal to endorse Hillary Clinton over Obama indicated as much). Gore didn't endorse Obama until right after he'd secured the nomination, but the two were said to have talked regularly. That's good enough.

Finally: Man, would I love to see the Republicans try to swat down a Gore nomination. How? They'd poke around in his finances, remind America that he's now divorced. But unless there were some kind of smoking gun on the former point, no one would care. They could not really block Gore; too much stature, too obviously qualified. Can you imagine? John McCain would grind his teeth, assuming those still are his teeth, down to dust. That would be awesome to watch.

Researchers Develop a Self-Filling Water Bottle that Harvests Water from the Air

There is water in the air around us at every moment. While this may not seem very significant if you live in a water-rich area, this untapped resource could benefit everyone from athletes on the go to people living in arid areas of the world. Taking a cue from the Namib Desert Beetle, scientists have developed a water bottle that can fill itself up by harvesting water from the atmosphere.

The Namib Desert Beetle has a shell that is covered in bumps, which allows humidity in the air to gradually accumulate on its back until water droplets form. These droplets roll down the beetle’s back and directly into its mouth, allowing the insect to survive in environments where ground water is scarce. Researchers have mimicked this shell to develop a bottle that utilizes the same water collecting effect. This technology can also be used on tent covers, roof tiles and other items.

NBD Nano is taking advantage of this technology to create a water bottle that can continually fill itself up. The company hopes to have the water bottle on the market by 2014. “We see this being applicable to anything from marathon runners to people in third-world countries, because we realize that water is such a large issue in the world today, and we want to try to alleviate those problems with a cost-efficient solution,” says Deckard Sorensen, co-founder of NBD Nano.

There are nearly four quadrillion gallons of water in the air, yet people all over the world are still thirsty. Scientists have been working to break into this untapped resource for over a decade, and are making some incredible breakthroughs.
