May Breaks Heat Record for 13th Consecutive Month
"Last month was the hottest May on record and marked the 13th consecutive month to break global temperature records, according to the National Oceanic and Atmospheric Administration."
Cathay sets biofuels-based flight record, as new A350 ushers in renewable jet era at Hong Kong
"These days, Cathay Pacific trades under the slogan “Life Well Travelled” and the delivery of the first of 48 super-modern, super-quiet, super-chic Airbus 350-900s is another milestone for that branding — but it might as well be “Life Sustainably Travelled” because the plane that arrived in Hong Kong last night on delivery from Toulouse flew on a 10% biofuels blend."
Miscanthus top biomass crop for ethanol production, U of I says
"The University of Illinois compared ethanol production methods with miscanthus, switchgrass and corn stover as feedstocks.
A recent study simulated a side-by-side comparison of the yields and costs of producing ethanol using miscanthus, switchgrass, and corn stover."
How to Convert Switchgrass to Ethanol
"Biofuels such as ethanol are compounds derived from plants that can be used to fuel internal-combustion engines such as those in cars and small machinery. Creating these fuels from plants can reduce the environmental and political problems caused by a reliance on oil. Although much ethanol production, especially in the United States, comes from corn, switchgrass is a promising alternative. It is a North American native grass that can grow on marginal land without the extensive inputs that corn or sugar cane require, and it produces a much better energy yield. Making ethanol from switchgrass, though, is a challenging process."
Grassoline: Can we fuel cars with grass?
"Research into sources for biological fuels -- biofuels -- has included everything from chicken fat to wood chips. But processing most of them yields a low net energy ratio -- the amount of energy each unit puts out isn't much more than the energy put into its production. Cost has also been a problem: Techniques for extracting fuels from plant and animal resources are currently expensive, which would be reflected at the fuel pump. But the more researchers crunch the numbers on switchgrass, the more it looks like a good candidate for an alternative fuel source."
Thank Me Later: New Planet-Saving Bacteria Eats Switchgrass, Makes Biofuel
"People keep saying the biofuel market isn’t going anywhere, but the folks at Lawrence Berkeley National Laboratory have a new trick up their sleeves. They have developed a new super-hardy strain of the bacteria E. coli, and they have demonstrated that it can make a critical biofuel precursor from switchgrass using a simple, low cost “one-pot” process."
Biofuels Plant in Hawaii Is First to Be Certified as Sustainable
The trucks roll in and out of the plant at a business park nestled near papaya farms and a forest preserve on the Big Island here, an operation that transforms waste cooking oils, animal fats, fruit and seeds into biodiesel fuel, nearly 13,000 gallons a day.
Biodiesel one slick solution, but more to come
"Teams of undergraduate students huddled quietly around the gray metal desks in the teaching labs at Harvard’s Science Center. Each group was creating a calorimeter out of a used soda can and scavenged Styrofoam cups to determine the energy density and efficiency of the biodiesel they had extracted the week before from waste fryer oil provided by Annenberg Dining Hall."
Five Solomon Islands Disappear Into the Pacific Ocean as a Result of Climate Change
"Five of the Solomon Islands have submerged underwater and six more have experienced a dramatic reduction in shoreline due to man-made climate change, according to a paper published in the journal Environmental Research Letters."
Supreme Court blocks Obama climate change rules
"The Supreme Court on Tuesday dealt President Barack Obama a blow by moving to temporarily block his administration's rules to limit greenhouse gas emissions from power plants."
