Hackers could use vulnerable charging stations to prevent the charging of electric vehicles in a certain area, or possibly even use the vulnerabilities to cripple parts of the electricity grid, a security researcher said during the Hack in the Box conference in Amsterdam on Thursday.

Recyclers disagree on impact of glued-in Retina MacBook Pro batteries
Submitted by l33tdawg on Thu, 2012-07-19 00:11
Apple's solution to shaving thickness from the Retina MacBook Pro—gluing its lithium polymer battery cells directly to the aluminum unibody shell—continues to spark debate among proponents of sustainable electronics. Apple submitted the device to the Green Electronics Council for an EPEAT Gold rating last week, prompting critics to argue that the glued-in battery should disqualify it from any rating at all. But it turns out that some recyclers disagree, saying it isn't dramatically more difficult to safely remove the battery than in other modern devices.

Researchers harness engineered viruses to produce electrical energy
Submitted by l33tdawg on Wed, 2012-05-16 09:52
Researchers from the US Department of Energy's Lawrence Berkeley National Laboratory have found a way to generate power using harmless viruses that convert mechanical energy into electricity.
The scientists tested their approach by creating a generator that produces enough current to operate a small liquid crystal display. It works by tapping a finger on a postage stamp sized electrode coated with specially engineered viruses. The viruses convert the force of the tap into an electric charge.

Google axes clean energy hacking
Submitted by l33tdawg on Thu, 2011-11-24 06:52
Google yesterday pulled the plug on an ambitious green-technology initiative, a casualty of the Internet giant's strategy to shed peripheral projects.
In a company blog, Google's senior vice president of operations and Google Fellow Urs Holzle listed "Renewable Energy Cheaper than Coal" as one of seven projects that were being shut down because they didn't catch on as hoped.
