Use your Mac's internal graphics to save battery life

If you have a MacBook system that contains dual graphics cards, then you have the option of enabling either the internal graphics or the discrete graphics card, depending on the hardware demands of the tasks you are running.

Integrated or "internal" graphics functions are included on the Intel processor in your Mac (though some prior Mac systems used Nvidia chipsets with Nvidia-branded internal graphics). This graphics option is relatively slow but also draws far less power than a dedicated graphics processor. The integrated graphics are powered fully when the system is turned on.

If your system includes a … Read more

EnergySail promises wind-solar combo for cleaner shipping

Many shipping companies are experimenting with adding sails to cargo vessels. Here's a design in which the sails are also solar panels.

EnergySail is a concept by Japan's Eco Marine Power that harnesses and stores wind and solar power to reduce fuel costs and pollution. It would work as an additional source of power to a ship's main engines.

The devices would be fitted on anything from large bulk ore carriers to cable-laying ships, ferries, and coast guard patrol vessels, according to the company. An automatic control system would orient the sails and panels to catch the … Read more

Take a drive down the 'Route 66 of the future'

Dutch designer Daan Roosegaarde thinks we drive on dumb roads. So he teamed with mega European construction company Heijmans Infrastructure to create a vision of a "smart highway" for the Netherlands -- and possibly the rest of the world.

Perhaps the most exciting aspect of these future roads is the fact that two concepts of the bunch -- glow-in-the-dark roads and dynamic paint -- should arrive by mid-2013. The group plans to introduce the rest of the concepts before 2015, giving the world a glimpse at how technology could revolutionize the way we drive by making it a safer and more sustainable experience. … Read more

Titan supercomputer debuts for open scientific research

Forecasting for weather like this week's "Frankenstorm" may become a lot more accurate with the help of the Department of Energy's Titan supercomputer, a system that launched this month for open research development.

The computer, an update to the Jaguar system, is operated in Tennessee by Oak Ridge National Laboratory, part of the DOE's network of research labs. Researchers from academia, government labs, and various industries will be able to use Titan -- believed to be one of the two most powerful machines in the world -- to research things such as climate change and … Read more

How to tackle waking a stubbornly sleeping Mac

Sleep modes in OS X are designed to save power by shutting down unnecessary and power-hungry system components; however, there may be times after an update or other configuration change when the system hangs or otherwise malfunctions after being set to sleep.

OS X has two main sleep modes. The first is standard sleep, in which the system keeps the contents of its memory active by providing power only to the RAM chips. This allows quick wake-up times but also draws a touch more power as it requires uninterrupted power to maintain RAM contents. The second mode is hibernation, in … Read more

Google to use wind energy for Oklahoma data center

Google is going green at a data center in Oklahoma.

The search giant announced today that it has signed a deal with the Grand River Dam Authority to transition the energy supply for its Oklahoma data center to wind energy. According to Google, the supply will be powered by 48 megawatts of wind energy from the Canadian Hills Wind Project in Oklahoma. The Project is slated to come online later this year.

Although Google has signed deals in the past to use green, renewable energy, it's the first time the company will take it from a utility provider. In … Read more

NYT story on data center waste scares some, frustrates others

The New York Times today kicked of an investigative series on how the cloud's physical structures are affecting the environment with a first installment that offers some scary stats about energy waste. But some say the story unfairly depicts an Internet industry that has been making major strides in this area.

Taking into account a year's worth of reporting and research, the Times' James Glanz concludes that most data centers are wasting huge amounts of energy, which, puts the information industry "at odds with its image of sleek efficiency and environmental friendliness."

"Online companies typically … Read more

Cyberspying effort drops 'Mirage' on energy firms

Researchers have uncovered a new cyberespionage campaign being waged on a large Philippine oil company, a Taiwanese military organization and a Canadian energy firm, as well as targets in Brazil, Israel, Egypt and Nigeria.

The malware being used is called "Mirage" and it leaves a backdoor on the computer that waits for instructions from the attacker, said Silas Cutler, a security researcher at Dell SecureWorks' Counter Threat Unit (CTU).

Victims are carefully targeted with so-called "spear-phishing" e-mails with attachments that are "droppers" designed to look and behave like PDF documents. However, they are actually … Read more

Virus knocks out computers at Qatari gas firm RasGas

Less than two weeks after 30,000 computers at a Saudi oil company fell prey to a virus, a Qatari gas firm's Web site and corporate network are also down because of a virus.

An unknown virus has affected office computer systems since Monday, a spokesman for RasGas, the second largest producer of liquified natural gas in the world, told Arabian Oil and Gas.com today. The company's Web site, Rasgas.com, remained down, as well.

The virus has not impacted production operations or cargo deliveries, said the unidentified RasGas spokesman. The company is a joint venture between … Read more
