First green LED means a lighting revolution is fast approaching

When scientists at the National Renewable Energy Laboratory (NREL) tried to apply their expertise in solar cell technology to build a green LED light from the ground up, they surprisingly centered the objective at their very first try. In doing so they solved a long-standing technological problem and paved the way for the large-scale employment of white LEDs for public and domestic illumination over the course of the next few years.  Read More

Chemist Robert Perry checks a flask containing an ingredient similar to those found in sha...

New York-based scientists believe that materials closely resembling ingredients found in hair-conditioning shampoos and fabric softeners might be used to “scrub” carbon dioxide (CO2) from coal-burning emissions. These aminosilicones show potential as a less expensive and more efficient alternative to current technologies with tests resulting in removal of up more than 90 percent of CO2 from simulated flue gas.  Read More

Unveiling the Ford Transit Connect Electric van

The Ford Motor Company chose the recent Chicago Auto Show to unveil its long awaited Transit Connect Electric van. The all-electric light duty commercial vehicle is the first in Ford’s accelerated electrified vehicle plan that also includes the Focus Electric in 2011, as well as a plug-in hybrid vehicle and next generation hybrid technology due in 2012.  Read More

Concrete seems pretty inoffensive. It just looks like mud, and appears to do nothing except sit there and harden. The fact is, though, concrete is the world's third-largest source of man-made carbon dioxide. Its production process accounts for at least 5% of the CO2 our species pumps into the atmosphere annually. Apparently, however, it doesn't have to be that way. Two companies are now using different technologies that not only make concrete carbon-neutral, they actually make it carbon-negative.  Read More

Toshiba LED light bulbs at CES 2010

Toshiba, was waving the green flag at CES this week in announcing that its E-CORE LED lightbulbs will soon be available in the US market. An E-CORE bulb has a life expectancy of 40,000 hours, which is 40 times longer than traditional incandescant lightbulbs and at the same time it reduces CO2 emissions by 85 percent in comparison.  Read More

Valuable paintings that are shipped or loaned to museums or other destinations around the world will soon have unusual traveling companions for their long journeys – sensors that can detect the buildup of pollutants within their specially-designed shipping crates. Occasionally, adhesives and other chemicals within the crates can breakdown and the fumes can damage the works of art. But the new sensors, developed by scientists at the Fraunhofer Institute for Silicate Research ISC in Würzburg, Germany, will detect these dangerous substances and help avoid the treasures being damaged.  Read More

Genetically engineered strains of the cyanobacterium Synechococcus elongatus in a Petri di...

As part of the push to reduce greenhouse gas emissions produced by burning fossil fuels researchers from the UCLA Henry Samueli School of Engineering and Applied Science have developed a greener way to extract biofuel from bacteria. The team has genetically modified a cyanobacterium to consume carbon dioxide and produce the liquid fuel isobutanol, which holds great potential as a gasoline alternative. As an added bonus that reaction is powered directly by energy from sunlight, through photosynthesis.  Read More

The Capstone Turbine Corporation's CMT-380 features a 30kW microturbine under the hood

Capstone Turbine Corporation has shown off its high performance hybrid electric car, the CMT-380, at the LA Auto Show. The car features a 30kW microturbine that extends the range of its traditional EV batteries, and which the company likens to having an ultra-clean and quiet jet engine under the hood. Capstone adds that the supercar, still in its test phase, reaches 0-60mph in 3.9 seconds, has a top speed of 150mph, and a range of up to 500 miles on a single tank of fuel - all with ultra-low exhaust emissions that rival any hybrid on the market today.  Read More

HydroLectricPower claims its HH2 system can turn just about any fossil fuel powered vehicl...

When the promoters of the HH2 Hydrogen Generator Clean Air Combustion System made an appearance at last year’s LA Auto Show they attracted their fair share of skepticism. Hardly surprising given their claims of boosting the horsepower, performance, and mileage of existing vehicles through the addition of an aftermarket device that mixes hydrogen and oxygen extracted from water with existing fuel. But the naysayers haven’t discouraged the system’s developers as they are fronting up to the LA Auto Show again this year with even loftier claims thanks to improvements to their system.  Read More

Commercial aircraft are a major contributor to greenhouse gas emissions, but manufacturers and operators are taking steps to tackle the problem. Operators such as Virgin Atlantic have conducted demonstration flights using biofuel, and now KLM Royal Dutch Airlines has completed its first ever passenger flight powered by sustainable kerosene. Using a 50 percent biokerosene/50 percent normal jet fuel mix to power one of its four engines, a Boeing 747 carrying 40 select passengers last week circled the Netherlands for an hour in what KLM claims is the first flight of its kind in Europe.  Read More
