ZigBee and the Smart Home: Is security an issue?

September 5, 2013 2:56 pm | by Cees Links, Founder and CEO, GreenPeak Technologies | Blogs | Comments

In one of my earlier blogs, I shared that today maybe around 600 million homes have WiFi. People share their lives with their family and friends and execute their financial transactions wirelessly over the Internet without being overly worried about security, and, despite the recent NSA disclosures, I wonder whether many people have changed their online behavior....

Engineering American energy independence

August 20, 2013 9:37 am | by Bill Kerney, Contributor | Blogs | Comments

Fracking is dramatically increasing the recoverable reserves of America carbon-based energy supplies. but yesterday I just paid $4.15 to fill up my car at the USA gas station in Cardiff, Calif. There is a huge disconnect between supply and the price at the pump. Bottom-up solutions need to scale to make an impact.

Solving wind energy storage problems

July 31, 2013 8:41 am | by M. Simon, Technical Contributor | Blogs | Comments

When it comes to alternative energy, I have been a big fan of storage. Alternative energy will not be viable for large-scale power delivery to the grid without storage. My friend Clyde knows of my obsession with storage. He suggested I look into GE's new wind turbines that come with storage attached.

Tiny nanocubes help scientists tell left from right

June 28, 2013 2:53 pm | by EurekAlert! | News | Comments

In chemical reactions, left and right can make a big difference. A "left-handed" molecule of a particular chemical composition could be an effective drug, while its mirror-image "right-handed" counterpart could be completely inactive. That's because, in biology, "left" and "right" molecular designs are crucial....

The green death

April 30, 2013 3:45 pm | by M. Simon, Technical Contributor | Blogs | Comments

Being "green" has gone from a technical effort to economically reduce energy use and avoid waste where such avoidance makes sense to actively reducing our effectiveness to show how committed we are to the Green Religion. And there is so much of this going on. In my opinion we would be much better off worshiping trees. Or cows.
