Researchers mash Google Earth with electrical data to predict US grid problems

VERDE system ultimately enhances situational awareness and speeds recovery times from power outages

What do you get when you combine images from Google Earth and the brainpower from researchers at Oak Ridge National Labs? Well in this case you get a tool that enables real-time status of the national electric grid that federal state and local agencies can use to coordinate and respond to major problems such as wide-area power outages, natural disasters and other catastrophic events.

The Visualizing Energy Resources Dynamically on Earth (VERDE) system, announced this week, mashes together images and stats of everything from real-time status of the US electric grid and weather information to power grid behavior modeling and simulation.

VERDE ultimately enhances situational awareness and speeds recovery times from power outages, ORNL scientists said. The tool also can predict the transmission lines particularly at risk of storm damage as well as the population in specific areas likely to lose power as a result of destructive winds from storms, ORNL said.

"With this tool we are able to monitor individual transmission lines and place the system as a whole in the context of potential impact on population, transportation and critical infrastructures," said Mallikarjun Shankar of ORNL's Computational Sciences and Engineering Division in a release.

Protecting the power grid is also one of the goal behind a new project at the Johns Hopkins University Applied Physics Laboratory. Researchers there were recently awarded a National Science Foundation grant to perform an experiment called the Active Magnetosphere and Planetary Electrodynamics Response Experiment (AMPERE) that will employ the Iridium constellation of 66 communications satellites and software to measure the electric currents that link Earth's atmosphere and space. By measuring this component of the space weather system, AMPERE will allow 24/7 tracking of Earth's response to supersonic blasts of plasma ejected from the sun, which can damage satellites high-altitude aircraft and electric power grids.

Dynabook Portégé X30L-G

Ultimately this laptop has achieved everything I would hope for in a laptop for work, while fitting that into a form factor and weight that is remarkable.

Tom Sellers

MSI P65

This smart laptop was enjoyable to use and great to work on – creating content was super simple.

Lolita Wang

MSI GT76

It really doesn’t get more “gaming laptop” than this.

Jack Jeffries

MSI GS75

As the Maserati or BMW of laptops, it would fit perfectly in the hands of a professional needing firepower under the hood, sophistication and class on the surface, and gaming prowess (sports mode if you will) in between.

Taylor Carr

MSI PS63

The MSI PS63 is an amazing laptop and I would definitely consider buying one in the future.

Christopher Low

Brother RJ-4230B

This small mobile printer is exactly what I need for invoicing and other jobs such as sending fellow tradesman details or step-by-step instructions that I can easily print off from my phone or the Web.
