Wood pulp extract stronger than carbon fiber or Kevlar
The Forest Products Laboratory of the US Forest Service has opened a US$1.7 million pilot plant for the production of cellulose nanocrystals (CNC) from wood by-products materials such as wood chips and sawdust. Prepared properly, CNCs are stronger and stiffer than Kevlar or carbon fibers, so that putting CNC into composite materials results in high strength, low weight products. In addition, the cost of CNCs is less than ten percent of the cost of Kevlar fiber or carbon fiber. These qualities have attracted the interest of the military for use in lightweight armor and ballistic glass (CNCs are transparent), as well as companies in the automotive, aerospace, electronics, consumer products, and medical industries.

WWII veteran creates bird-friendly wind turbine
World War II veteran Raymond Green, an 89 year old resident of Jackson, California, has created a working prototype of a "bladeless" wind turbine which is bird and bat-friendly, and very quiet in operation. Though still in development at present, Green intends his design to be produced in various sizes, from smaller personal versions to much larger turbines which could be implemented in wind farms.

Appearing at IFA, Panasonic has unveiled a brand new refrigerator which the company states is the first-ever A+++rated two-door refrigerator – making it the most energy-efficient two-door fridge, worldwide. Named the NR-B55VE1, it consumes 262 kWh/year of electricity, which by our reckoning amounts to a mean power consumption of 30 W. Gizmag was on hand to take a look. Read More
At first glance, photovoltaic solar panels are brilliant. They’re self-contained, need no fuel and so long as the sun is shining, they make lots of lovely electricity. The trouble is, they’re expensive to make, batteries are poor storage systems for cloudy days, and the panels have a very short service life. Now, Dr. Mikhail Zamkov of Ohio's Bowling Green State University and his team have used synthetic nanocrystals to make solar panels more durable as well as capable of producing hydrogen gas.

A team of physicists from the University of Oregon (UO) has calculated that cooling the emissions from coal-fired power plants would result in a reduction of the levels of dangerous chemicals entering the atmosphere, including CO2, by 90 percent. While cryogenic treatment would also see a 25 percent drop in efficiency, and therefore result in electricity costs increasing around a quarter, the researchers believe these would be offset by benefits to society, such as reductions in health-care and climate-change costs.

The bunker fuel used in cruise liners and freighters is some of the cheapest, crudest fuel available. It’s also among the dirtiest. Scientists from the Maine Maritime Academy and SeaChange Group LLC led by George N. Harakas, Ph.D announced at the 244th National Meeting & Exposition of the American Chemical Society that they have developed what they call "Bunker Green" fuel. This fuel uses an ingredient commonly used in food and medicine to reduce sulfur and other emissions in ocean vessels. Read More
Some people believe that there’s no problem that peanut butter, chocolate and whipped cream can’t solve. These people could be onto something with news that a team of researchers has developed a new, safer oil dispersant that uses edible ingredients found in the aforementioned trio of treats. The new dispersant could save the lives of thousands of birds and animals caught in environmental catastrophes. Read More
Computing guzzles a great deal of electricity and striving for greater energy efficiency both saves money and decreases greenhouse gas emissions. Although computers already come with energy-saving mechanisms, such as sleep mode and other power saving features set by users, there's always room for improvement. This is the idea behind Ecobeneficios’s Greencam. The Brazilian company has launched a PC app that automatically turns off the user’s monitor when he or she walks away from it. Read More
"Biorefinery" converts Starbucks waste into useful product
Every year, the individual stores that make up Starbucks Hong Kong produce almost 5,000 tonnes (4,536 tons) of used coffee grounds and unconsumed bakery items. As it stands now, all of that waste is incinerated, dumped in a landfill, or composted. In the future, however, it may be used to produce a key ingredient in laundry detergents, plastics, and many other items. A recent experiment showed that it can indeed be done. Read More
Although optical drives in consumer notebooks are becoming less common nowadays and we are storing more and more of our digital information on hard drives instead of optical discs, CD/DVD players are still a mainstay of desktop computers and business laptops and new systems often come bundled with discs containing all sorts of never-to-be-used software. With the help of its Laboratories Division, Fujitsu has developed a new recycling system to make new front panels for notebook computers from all the discarded CDs and DVDs collected, sorted and recycled by its five recycling centers across Japan.
