New Engine ‘Breakthrough’ Improves Ethanol Efficiency in Flex-Fuel Vehicles 9.2.2009 TreeHugger
Ricardo claims its new engine eliminates losses in fuel efficiency in flex fuel vehicles running on ethanol. Photo: via flickr Leave aside land-use concerns, the effect on the food supply, or any other concerns you may have about ethanol for the next few paragraphs, because this post has nothing to do with those. It has to do with another of the problems ethanol faces: Reduced engine efficiency in flex-fuel vehicles. Engineering firm has announced that it has tackled that problem, achieving a “breakthrough efficiency for e... ...

New Fuels for Fuel: Making it from Waste 9.2.2009 Environmental News Network
Enerkem, a Montreal maker of biofuels and green chemicals, says it's nearly ready to start cranking out second-generation biofuels on a commercial scale. The company's approach is to turn waste materials (it's starting with old utility poles) into a synthetic gas "syngas," which it will then use as a chemical feedstock for making both ethanol and methanol, using a gas-to-liquid conversion. But—and here's where it gets very promising-the company claims it will eventually be able to use municipal waste (all the stuff that's left over after recycling and composting) into syngas.

New Study Finds Corn-based Ethanol More Harmful Than Oil-based Gasoline 8.2.2009 TreeHugger
Photo via: Silfverduk Currently in the news, the producers of ethanol are pressing their thumbs to the government, asking them to overturn the limiting the mix of ethanol which can be added to gasoline from its current 10 percent to as much as 15 percent. In the meantime, the Agricultural Department is in discussions with the EPA on in order to help protect the ethanol industry, which has been deemed ... ...

Biofuels more harmful to humans than petrol and diesel, warn scientists 3.2.2009 Environmental News Network
Some biofuels cause more health problems than petrol and diesel, according to scientists who have calculated the health costs associated with different types of fuel. The study shows that corn-based bioethanol, which is produced extensively in the US, has a higher combined environmental and health burden than conventional fuels. However, there are high hopes for the next generation of biofuels, which can be made from organic waste or plants grown on marginal land that is not used to grow foods. They have less than half the combined health and environmental costs of standard gasoline and a third of current biofuels.

Billion-year revision of plant evolution timeline may stem from discovery of lignin in seaweed 27.1.2009 Environmental News Network
Land plants' ability to sprout upward through the air, unsupported except by their own woody tissues, has long been considered one of the characteristics separating them from aquatic plants, which rely on water to support them. Now lignin, one of the chemical underpinnings vital to the self-supporting nature of land plants – and thought unique to them – has been found in marine algae by a team of researchers including scientists at UBC and Stanford University.

Algae Farming In The Face Of The Oil Price Situation - Still a Viable Alternative Fuel Source? 22.1.2009 Green Technology and Environmental Science News - ENN
Algae farming is a relatively safe bet in the current financial climate. Algae, a sludge colored illuminatingly lime to moss green, has going for it that it can be made anywhere –even in desert climates- and that it can be relatively swiftly adopted. A big negative is that the price of producing one gallon worth of algae based petroleum is still relatively cost inefficient compared to oil. But even at the negative end of this spectrum, there’s masses of potential.

Novel energy options 13.5.2006 Good News India
As petroleum inches unstoppably towards $100 a barrel and global warming is a widely shared experience, it is nice to know there are solutions for a future without either of these. Here is a round-up of some options for Indian researchers and experimenters to get started on. These developments are from overseas and are worth our attention. The appeal of biodiesel is well known but there are concerns that when land use is changed to produce liquid fuel, food production may suffer and famines ensue. Tree based oils -as against those derived from field crops- do a…
