A team of researchers led by Newcastle University has produced an all-in-one Biofuel Micro Trigeneration (BMT) prototype system fueled entirely by unprocessed plant oils that provides combined cooling, heating, and electrical power. This first-generation system is designed for use in homes, with the potential for up-scaling for larger commercial and industrial applications.  Read More

Despite efforts to limit their use through implementation of charges or bans, billions of plastic bags continue to clog landfills, waterways and the world's oceans every year. Already a potential source for carbon fiber and carbon nanotubes, researchers have provided another reason not to throw the ubiquitous bags away by converting them into a range of petroleum products.  Read More

By now, most people have at least a passing knowledge of biodiesel – it's diesel fuel made from plant or animal oils, as opposed to the more traditional and less eco-friendly petroleum. While it's a good choice for people with diesel-powered vehicles, those of us with gas-burning cars haven't been able to get in on the action ... although that may be about to change.  Read More

Stefanie Kring studies zooplankton gathered from wastewater lagoons

With dwindling non-renewable fuel sources creating an enormous energy challenge, the search is on to develop sustainable, renewable types of energy such as solar, wind and biofuel. One of the recent developments in this field comes from New York's Clarkson University, where new findings suggest that small organisms found in wastewater treatment lagoons could be used as biofuel feedstock.  Read More

Boeing is seeking approval to fly aircraft on green diesel

Over the past few years, we've heard about "green" airliners running on a mixture of jet fuel and biofuels made from things like plants and recycled cooking oil. Now, Boeing is looking at blending jet fuel with green diesel, which is already used to fuel trucks.  Read More

UK-based Biobot has introduced a simple chemical reactor for converting used kitchen oils ...

One difficult aspect of a greener lifestyle involves disposal of used cooking fats. Most people either pour it down the drain, where it can lurk for years while conspiring to clog your pipes, or pour it in the yard, where it attracts pests of various sorts looking for a free meal. Recycling is obviously a better option, and to this end the BioBot 20 tabletop diesel processor – a (relatively) simple chemical reactor for converting used kitchen oils into biodiesel fuel at home – has been introduced by UK-based company Biobot.  Read More

Graduate student Zachary Baer works with a fermentation chamber to separate acetone and bu...

Researchers at the Energy Biosciences Institute (EBI) are generating bio fuels from renewable sources, such as sugar and starch, using a process that could be commercialized in as little as five to ten years. Although the fuels are currently more expensive to produce than those made from petroleum, they contain more energy per gallon than ethanol and the researchers say that, if adopted, could help to cut greenhouse gas emissions from transportation.  Read More

US$150,000 Trident Iceni 70 mpg biodiesel supercar set for launch (again)

One of the most interesting supercars of recent years that has always bordered on the edge of vapourware, looks like finally becoming a reality. Fraught with on-again-off-again production arrangements, management-changes, restructuring, redesign and refinancing for almost a decade, the Trident Iceni is finally slated for launch at the UK’s Cholmondeley Pageant of Power on July 15. At the heart of the sleek Iceni is a modified 550 bhp GM 6.6 liter twin-turbo diesel V8 running bio-fuel, and according to previously released info, the Iceni will run to 230 mph, accelerate from 0-60 mph in under four seconds, and deliver 70 mpg at a constant 70 mph. It will also have 100,000 mile service intervals, and is expected to sell for around US$150,000.  Read More

The Eco Fire Pot Stove is designed to allow women in developing nations to cook using rela...

Chances are that even if you own a propane camp stove, you’ve tried cooking over an open fire at least once. When you did, despite your best efforts, you probably ended up sucking down a lot of smoke in the process. Now, imagine doing that for every meal. For many women in the developing world, breathing in toxic smoke while cooking over a wood, kerosene or coal fire is part of their daily routine. Not only can it have a detrimental effect on their own health, but it also worsens local air pollution and (in the case of wood fires) deforestation. The Eco Fire Pot Stove, however, is designed to allow these women to cook while breathing clean air.  Read More

Microscopic image of the biodiesel emulsion fuel created by researchers

Nanoparticles have added yet another string to their microscopic bows with a new study showing that the addition of alumina nanoparticles can improve the performance and combustion of biodiesel, while producing fewer emissions. In the study, a team at India’s National Institute of Technology in Tiruchirappalli used nanoparticles with an average diameter of 51 billionths of a meter. The high surface-to-volume ratio of the nanoparticles means they have more reactive surfaces, which allows them to act as more efficient chemical catalysts and results in increased fuel combustion.  Read More
