A team of scientists led by the University of Colorado Boulder has discovered an invisible “Star Trek”-style shield that blocks so-called “killer electrons” 7,200 miles above Earth.
The electrons, which travel at near light-speed, are capable of damaging space electronics and can put astronauts in danger.

World's First Underwater City Powered by Sustainable Energy
Shimizu Corp.’s vision of the modern-day Atlantis is divided into three parts, with the underwater city contained in a 1,600-feet-wide sphere that could house up to 5,000 residents and comprise mixed-use developments where people can live, work, and play.

Amazing! Keeping energy insted of battery million rechargeable
Graduate student Andrew Westover and Assistant Professor of Mechanical Engineering Cary Pint have developed a supercapacitor that stores electricity by assembling electrically charged ions on the surface of a porous material, instead of storing it in chemical reactions the way batteries do.

Facebook Internet Drones
Yael Maguire, the engineering director at Facebook‘s Connectivity Lab, has revealed further details about the social media giant’s plans to expand internet access to communities worldwide. In order to achieve global connectivity, the company has been discussing using drones, or planes as they prefer to call them, that will constantly circle in the skies. In conversation with Mashable CEO Pete Cashmore, Maguire stated the planes would be “roughly the size of a commercial aircraft, like a 747.” As astounding as that revelation is on its own, it also raises regulatory questions. Not only are there unresolved issues around launching and airspace controls, but with an anticipated need for thousands of planes, the company says it is impractical for one person to control only one plane at a time as current legislation requires.
Don't Miss! Free Solar Power System
IBM Research and Swiss solar technology company Airlight Energy just unveiled a cutting-edge solar system that resembles a 10-meter-high sunflower! The High Concentration PhotoVoltaic Thermal (HCPVT) system can concentrate the sun’s radiation 2,000 times and convert 80 percent of it into useful energy, generating up to 12 kilowatts of electrical power and 20 kilowatts of heat on a sunny day—enough to power several average homes. Oh, and it can also produce clean, fresh water as a result of the process used to cool the solar cells!
First, the nitty gritty specs: The design features a 40-square-meter parabolic dish made of a patented fiber-based concrete. This concrete has mechanical characteristics similar to those of aluminum, but at 20 percent of the cost. The inside of the dish is covered with 36 elliptic mirrors made of recyclable, silver-coated plastic foil that is only slightly thicker than a chocolate wrapper. This mirrored surface area concentrates the sun’s radiation by reflecting it onto microchannel liquid-cooled receivers. Each receiver is covered with a dense array of one centimeter square photovoltaic chips that can produce up to 57 watts each on a sunny day. Seemingly thinking of everything, the team has also designed a large, inflated, transparent plastic enclosure for the mirrors and the receiver, which protects them from rain and dust and prevents birds and other animals from getting fried.
The concentrators use a direct hot-water cooling design that IBM already uses in its high-performance computers and supercomputers. However, with a bit of customization, the HCPVT system can also provide drinkable water and air conditioning from the hot water output produced. The team notes: “For example, salt water can pass through a porous membrane distillation system, where it is vaporized and desalinated. Such a system could provide 30–40 liters of drinkable water per square meter of receiver area per day, while still generating electricity with a more than 25 percent yield or two kilowatt hours per day—a little less than half the amount of water the average person needs per day according to the United Nations, whereas a large multi-dish installation could provide enough water for a town.”
But wait, there’s more! Airlight Energy and the IBM Corporate Service Corps are donating one of these systems to two deserving communities. Each winning community will receive a prototype HCPVT system from Airlight Energy, and be eligible for pro bono “enablement and transformation support” from IBM Corporate Service Corps. Applications from communities will be open in 2015 with winners announced in December 2015, and installations beginning in 2016.

Flower Solar Collector
When it comes to capturing the energy of the sun, what better model is there than photosynthetic plants? Researchers at North Carolina State University have cultivated a beautiful crop of germanium sulfide (GeS) “nanoflowers” that could be used to create next generation solar cells and ultra high-density energy storage systems. The nanoflowers have petals that resemble those of a geranium or marigold – although they’re only 20-30 nanometers thick and they’re capable of storing much more energy than traditional energy storage cells.
Park Gate Project
From Dog waste (dog poo) to energy
A new project in Cambridge, MA dubbed the “Park Spark” has dogs powering the street lights in their own dog parks. Designed by Matthew Mazzotta, a visual artist with a degree from MIT, the project uses dog poop from the park to produce methane, which is then burned to light the park at night. The project was funded through the Massachusetts Institute for Technology and a partnership with the City of Cambridge, and it will hopefully spark a dog poo-fueled revolution of biogas-powered parks across the country.
Ever wonder what happens to all of those dog droppings deposited into public trash cans? The “waste” sits in the trashcan and continues to give off methane. When the trash is picked up, the dog waste is sorted out and sent to the appropriate cleaning facility—where it continues to give off methane.

Crazy tennis court
This crazy tennis court have to add it to my list of questionable ideas. As part of a big media splash designed to drum up business for the Dubai Duty Free Men’s Open in 2005, the turf court was put on top of the 1,000 foot Burj al Arab tower along the Persian Gulf. At these dizzying heights, Andre Agassi and Roger Federer were invited to play a friendly (and no doubt slow) round of tennis before the Open officially started.
Hybrid Energy from Samsung
Why just harness light or vibration individually when you can use both to create electricity? Making sure to fully exploit both sun and sound simultaneously, researchers from Sungkyunkwan University and Samsung Advanced Institute of Technology in South Korea have engineered a novel new device standing only 300nm tall. Publishing their work in the most recent issue of Nanotechnology, the team explained how their hybrid harvester could take advantage of the separate sources of energy to produce a single, constant output of electricity.

The largest oil field in the world
The largest oil field in the world was discovered yesterday just 30 kilometers off Scotland’s coast.
As many Scots reeled from the defeat of their push for independence, the British government announced that the massive oil field has the potential to produce up to 15 million barrels a day, if not more, generating trillions of dollars annually for decades.
Located within Scotland’s territorial waters in the North Sea, near the coastal city of Aberdeen, the oil field measures about 560-by-80 km (348-by-50 miles), surpassing the second-largest, Saudi Arabia’s Ghawar Field, which produces 5 million barrels a day.
“To think we believed Scotland’s oil was running out, when there’s enough oil here to last hundreds and hundreds of years,” Jock Grant-Menzies of the British Treasury told BBC News. “I would hate to be in the Middle East right now. Whoever controls these Scottish oil fields controls the world.”
Scotland’s North Sea oil and gas reserves were a source of contention during the referendum on Scottish independence, with supporters and opponents disputing how much oil was left and if it could economically sustain an independent Scotland.
British Prime Minister David Cameron hailed the lucrative oil field’s discovery, noting it “will make London richer than Dubai.”
Ten Largest oil producing countries in the world
Oil is a the most precious usable and important source of energy in the world. Oil production means the sum of crude oil barrels extracted on daily basis through the drilling process. Most nations have Considerably effected by the innovations and developments in the oil market. Its need and consumption is increasing day by day.its demand is increasing at highest rate in all over the world. In different nations it is produced through a process which may differ and sometimes same. different constituents are extracted from crude oil , such as petroleum, gasoline etc.
