Jatropha Curcas: Promising Biofuel Feedstock Or Invasive Species?
August 28, 2007 07:27 PM - Bruce Mulliken, Private Landowner Network
Generally speaking, transplanting a species from one part of the world to another - either accidentally or on purpose - has, on occasion, had some really negative consequences. A prime example is kudzu that was moved from Asia to the southeast US beginning in the 1930’s to control erosion. It did that but now kudzu overgrows just about everything in its path and is almost impossible to get rid of. Now, with the push to find alternative and renewable sources of fuel in the US and elsewhere, oil from the seeds from a shrub called Jatropha Curcas has arisen as a very good source of biodiesel.

Europe Wants To Turn Wine Into Biofuel
August 28, 2007 06:30 PM - Reuters
BRUSSELS - The European Union has opened a tender to sell unwanted wine in four countries for use in making bioethanol, its Official Journal said on Tuesday. The tender would offer roughly 693,376 hectoliters of wine alcohol stored in France, Greece, Italy and Spain. The deadline for bids was September 10, it said in its latest edition. France, the world's largest wine producer, would offer 239,995 hectoliters of wine alcohol for distillation, while Italy and Spain would offer 200,000 hectoliters apiece. The balance of roughly 53,381 hectoliters will come from Greece.
Bacteria Sense Light, Use It To Regulate Virulence
August 28, 2007 04:39 PM - UC Santa Cruz
University of California, Santa Cruz - The bacteria that cause brucellosis can sense light and use the information to regulate their virulence, according to a study in the August 24 issue of the journal Science. The discovery comes after 120 years of research into the disease, which causes abortions in livestock and fevers in humans. Researchers found that two other bacteria, including a species that attacks plants, sense light using the same type of protein structure, and at least 94 more species possess the code for it in their DNA.
A Better, Cheaper Way To Make Biofuels: Algae
August 28, 2007 03:56 PM - Paul Schaefer, ENN
GILBERT, Ariz. - An Arizona company says they've developed a better, cheaper way to make biofuels, and more of it, from algae. Diversified Energy Corporation has developed a "breakthrough algae production system". The system is called "Simgae", for 'simple algae'. It utilizes common agriculture and irrigation components to produce algae at a fraction of the cost of competing systems. At 1/2 - 1/16th the capital cost, profitable oil production costs at $0.08 - $0.12/pound, and low operations and maintenance requirements, the system offer the biofuels industry access to cheap and readily available oils and starches for the production of biodiesel, ethanol, and other renewable fuels.
New Optical Fiber Home Network Demonstrates 100Mb Capacity
August 28, 2007 12:47 PM - Paul Schaefer and Quinn Shanahan, ENN
DENVER - Mitsubishi International and partner Firecomms says they'll demonstrate a new home network with a transmission rate of 100 Mb of Ethernet content. The trick, the company says, is a network entirely comprised of Polymer Optical Fiber. That increase in capacity is a big jump from existing home capacity say experts. The technology means web pages that load faster, video with fewer breaks and potentially more resolution.
International Consortium Is Created to Build World's Largest Submillimeter Telescope
August 28, 2007 11:50 AM - Caltech
Five institutions from North America and Europe have created a consortium to oversee the building of a 25-meter submillimeter telescope on a high elevation in Chile. When completed in 2013, the $100 million instrument will be the premier telescope of its kind in the world. The project is formally known as the Cornell Caltech Atacama Telescope (CCAT), and has been in the works since a $2 million feasibility/concept design study was begun in 2004 by the California Institute of Technology and Cornell University. Now that the study has been completed, the partners are moving to the next phase of the process.
Cyclone Power Technologies Tests Fuel Made From Oranges

Engineers Perfecting Hydrogen-Generating Technology
August 27, 2007 08:12 PM - Emil Venere, Purdue University
WEST LAFAYETTE, Ind. - Researchers at Purdue University have further developed a technology that could represent a pollution-free energy source for a range of potential applications, from golf carts to submarines and cars to emergency portable generators. The technology produces hydrogen by adding water to an alloy of aluminum and gallium. When water is added to the alloy, the aluminum splits water by attracting oxygen, liberating hydrogen in the process. The Purdue researchers are developing a method to create particles of the alloy that could be placed in a tank to react with water and produce hydrogen on demand.
Israeli Researchers To Investigate Ocean Energy Source
