Researchers turned wood into a better insulator than Styrofoam
The research lab behind the creation of see-through wood has developed a new type of material that could be used as a cheaper, stronger and more environmentally friendly insulator. They're calling it nanowood and it insulates better than Styrofoam and silica aerogels. "This can insulate better than most other current thermal insulators, including Styrofoam," Tian Li, a researcher on the project, said in a statement. "It is extremely promising to be used as energy efficient building materials."
New carbon nanotube aerogel is now the world's lightest solid material
Frozen smoke (read: aerogel) -- not to be confused with the stuff your Grandma uses to flavor her turkey -- is the world's lightest solid material, and it just keeps getting lighter. Researchers at the University of Central Florida have created a new form of the super material, known as multi-walled carbon nanotube (MWCNT) aerogel, that has a density of just four milligrams per cubic centimeter and can be used in sensors to detect pollutants and toxic substances, chemical reactors, and electronic components. Aerogels, which are known as the world's most effective insulators, have been around since the early 20th century, but most of these are fabricated from silicon dioxide. In order to produce the new aerogel, researchers removed the liquid from a "wet gel of well-dispersed pristine MWCNTs," creating a honeycomb structure with walls just 100-nanometers thick. The resulting material is an impressive and resilient electrical conductor that looks and acts less like frozen smoke and more like a burnt marshmallow. And now, you know.

Die Electric socket blockers make better use of your AC outlets
We're all for conserving electricity and all, but preventing every one of your AC outlets from actually passing energy onto your favorite gizmo is indeed extreme. Nevertheless, we can't help but be impressed with the variety of Die Electric insulators, which take on a plethora of shapes to not only prevent your outlets from actually passing electricity onward, but double as helpful household accessories (or just plain weird wall adornments). Of course, any halfway industrious individual could probably concoct their own Die Electric, but if you must go straight to the source, prototypes are available for sale now.
Intel, IBM announce insulation "overhaul" for faster, cooler chips
Intel and IBM are acting oh-so-smug right now about their respective achievements in insulating 45nm transistors, allowing the chips to run faster, leak less power and generate less heat. Intel, which hinted at such improvements in June, knocked out the first press announcement, promising to start implementing the technology in the second half of 2007, and IBM scrambled to catch up, announcing that it was "on the verge" of a similar discovery, and was working with AMD to start building comparable chips in Q1 2008. Intel is calling this the "biggest change in computer chips in 40 years," and while that sounds like hyperbole to us, there's no denying that 45nm is the new hotness, and bully for Intel for making it work. The actual technology -- at least Intel's method -- replaces the silicon dioxide insulators which leak too much energy when sliced too thin, but when made thicker reduce the electrical charge that passes through, reducing performance. Now Intel is using a hafnium-based insulator, which improves conductivity and reduces leakage simultaneously. Just for kicks, Intel is also tossing in a new metal alloy for its gate electrode, to replace the old silicon gate. IBM confirmed it is also using hafnium insulators, but couldn't help getting in a cheap-shot metaphor: "It's the difference between can openers and Ferraris," according to Bernard S. Meyerson, VP and chief technologit for systems and technology at IBM. Man, those technologists can really bring the smack.[Thanks, Lee G.]
