mdsolar writes: The United States could lower carbon emissions from electricity generation by as much as 78 percent without having to develop any new technologies or use costly batteries, a new study suggests. There’s a catch, though. The country would have to build a new national transmission network so that states could share energy.
“Our idea was if we had a national ‘interstate highway for electrons’ we could move the power around as it was needed, and we could put the wind and solar plants in the very best places,” says study co-author Alexander MacDonald, who recently retired as director of NOAA’s Earth System Research Laboratory in Boulder, Colorado.

g8orade points out two recent articles in The Economist about the rise of cloud computing. The first discusses how software-as-a-service has come to pervade online interactions. "Irving Wladawsky-Berger, a technology visionary at IBM, compares cloud computing to the Cambrian explosion some 500m years ago when the rate of evolution sped up, in part because the cell had been perfected and standardised, allowing evolution to build more complex organisms." The next article examines how the cloud will force a "trade-off between sovereignty and efficiency." Reader pjones contributes news that the Virtual Computer Lab will be supplementing more traditional computer labs at North Carolina State University, and adds, "NCSU's Virtual Computing Lab and IBM are offering the VCL code as a software 'appliance' for use in schools to link to the program. Downloads are available at ibiblio at UNC-Chapel Hill. The VCL also is partnering with Apache.org to make the software available and to allow further community participation in future development."

Rob MacKenzie writes "I have to decide on a mobile phone to develop for. We're building a house with some automation built in, and we want the mobile phone to be able to control certain aspects of it, and retrieve information on what's going on in the house. Our choices are the usual suspects: Apple's IPhone, RIM's Blackberry, Nokia's line (Symbian), any Android phone we can get in Canada, J2ME generic app, or a Web-based UI we would interact with in the phone's browser. What would you choose if you had to go with one? Which exact model? We will be buying a few to develop for, so price is a bit of an issue."
