    Frederic Scheer is biding his time, convinced that by 2013 the price of oil will be so high that his bio-plastics, made from vegetables and plants, will be highly marketable. Scheer, 55, is the owner of Cereplast, a company that designs and makes sustainable plastics from starches found in tapioca, corn, wheat and potatoes. He has believed for the past 20 years that the price of oil will eventually make petroleum-based plastics obsolete and clear the way for his alternative. "The tipping point for us is 95 dollars a barrel," he said. At that price "our product becomes cheaper" than...

    Fungi are single or multi-celled organisms that break down organic materials, such as rotting wood, in order to absorb their nutrients. Neither plant nor animal, they range from mushrooms to single-celled yeast. Scientists were investigating organic chemicals trapped in an Italian sedimentary rock formation when they found evidence that an extinct fungus feasted on dead wood during a time when the world’s forests had been catastrophically eradicated.[1] What could have caused such a universal effect on forests, and why does organic material remain in rocks that are supposedly 251.4 million years old?...

    MCLEAN, Va., Oct. 19 (UPI) -- U.S. Navy officials laid out a series of initiatives intended to change the way the force uses energy, including the increased use of renewable resources. U.S. Secretary of the Navy Ray Mabus unveiled a series of measures at an energy forum in Virginia. The measures include a shift toward long-term energy savings, the increased use of hybrid and electric vehicles and the creation of a so-called Green Strike Group composed of nuclear- and biofuel-powered vessels. The U.S. Department of Defense is the largest consumer of petroleum products in the United States, using roughly 330,000...

    WAUSAU, Wis. — Waterways across the upper Midwest are increasingly plagued with ugly, smelly and potentially deadly blue-green algae, bloomed by drought and fertilizer runoffs from farm fields, that's killed dozens of dogs and sickened many people. Aquatic biologists say it's a problem that falls somewhere between a human health concern and a nuisance, but will eventually lead to more human poisoning. State officials are telling people who live on algae-covered lakes to close their windows, stop taking walks along the picturesque shorelines and keep their dogs from drinking the rank water.

    Algae, paper and salt-water are the key components of thin and flexible new batteries, report Swedish researchers. Cellulose obtained from the bright green Cladophora algae proved to be key to the project, as it boasts a unique nanostructure with a high surface area. Although the batteries have lower voltage and power density than conventional batteries, their low cost and flexibility hold great promise for applications where metal-based batteries are impractical. The research is the product of a collaboration between two teams at Uppsala University in Sweden: Maria Strømme's group, who identified the potential of the algal cellulose, and Leif Nyholm's group, who...
  • Turning Algae Into Oil, with Help from Fish

    The New York Times ^ | August 12, 2009 | Matthew L. Wald
    There are two big problems associated with extracting liquid fuel from algae: getting the algae out of the water, and then getting the oil out of the algae. The pumps and centrifuges required to do this consume a lot of energy. A California company, LiveFuels, is trying out a new, less energy-intensive approach: It is feeding the algae to small fish — and letting them do the job of harvesting. After the fish fatten up, workers catch them in nets and process them for oil (as well as protein for animal feed). This is a bit like gathering whale oil,...

    The Energy & Environmental Research Center (EERC) at the University of North Dakota has been awarded a subcontract by Science Applications International Corporation (SAIC) to help produce jet fuel from algae. The effort is being funded by the U.S. Department of Defense's (DoD) Defense Advanced Research Projects Agency (DARPA) and is a continuation of the first successful production of 100% renewable fuel for the U.S. military by the EERC. Under a previous DARPA contract, the EERC advanced the development of a feedstock-flexible process that can utilize various crop oil feedstocks to produce combinations of renewable jet fuel, diesel and naphtha...

    The method, called catalytic hydrothermal gasification, creates natural gas out of algae - more quickly, more efficiently and at higher yields than other biofuel processes. Genifuel expects the process also requires less capital investment. The license agreement moves this technology for renewable energy production a step closer to commercial reality. Battelle operates PNNL for DOE. "Algae and other aquatic biomass hold significant promise for our country's ability to produce renewable energy domestically," said Genifuel President Jim Oyler. "At Genifuel we have developed efficient growth and harvesting techniques for the aquatic biomass. With this gasification process, we can convert the biomass...
  • A Strategy For Winning completely In Afghanistan in 3 years.

    A pretty good strategy for winning the Afghan war would be to drop in some ,biodiesal refineries that can produce diesel for "$1.25 to $1.75 per gallon from a variety of feedstocks that ranges from restaurant and ethanol-plant waste oils to non-edible crops and plain old pond scum." Drop those in the poppy valleys, kill the poppy plants and offer to pay the farmers for their dead poppy plants to use as feedstock for the biodiesal refineries. That diesal could be used for ground based vehicles. Interestingly, if you read this article, you'll note that the airline industry is far...

    > Biofuels technologies appear capable of someday producing 200,000 barrels of jet fuel a day—enough to supply the needs of the U.S. Air Force—from algae grown on less than 800,000 acres. [10-11 gallons per day or 3650-4000 gallons per year] “It’s not crazy to imagine that by the year 2050 we (the United States) could become an oil exporter again,” Briggs said. 80 million acres would replace the current oil demand of the United States. 3% of total land in the United States. Other estimates are 1-2% or less as the processes are improved. Light pipes allow for deeper algae...

    Deadly Waters No Problem for Well-Equipped Algae by Brian Thomas, M.S.* Arsenic is a common toxic component in pesticides and herbicides, and one place it is found naturally is in the hot springs of Yellowstone National Park. The arsenic in the water there would be deadly to many living creatures, yet the Cyanidioschyzon algae thrive in it because they are specially equipped to detoxify arsenic through chemical modification. Some bacteria, marine worms, and lichens are also known to convert between different forms of arsenic, but new research details how the algae do it....

    Speaking at the ECO:nonomics conference yesterday, John Doerr, Vinod Khosla, and Bryant Tongall said they're not interested in backing any companies working on algae biofuels. On the face of it, that makes sense. It's pond scum. However, algae was already used twice this year to fuel test flights of commercial planes. It was mixed with jatropha seed oil. But those test flights aren't enough to get major venture capitalists interested, even though Khosla said he looked at more than 100 algae biofuel companies. Environmental Capital: For Mr. Doerr of Kleiner, Perkins, Caufield & Byers, the problem is algae itself. To...

    In pursuing cleaner energy there is such a thing as being too green. Unicellular microalgae, for instance, can be considered too green. In a paper in a special energy issue of Optics Express, the Optical Society's (OSA) open-access journal, scientists at the University of California, Berkeley describe a method for using microalgae for making biofuel. The researchers explain a way to genetically modify the tiny organisms, so as to minimize the number of chlorophyll molecules needed to harvest light without compromising the photosynthesis process in the cells. With this modification, instead of making more sugar molecules, the microalgae could be...

    Green-colored polar bears are drawing questions from puzzled visitors at a Japanese zoo. Three normally white polar bears at Higashiyama Zoo and Botanical Gardens in central Japan changed their color in July after swimming in a pond with an overgrowth of algae. ... High temperatures in July and August and less-frequent water changes because of the zoo's conservation efforts caused an algae growth in the bear pond and safety moat, Kurobe said.

    Oil prices recently hit $140 per barrel. The cost to grow and transport food is rising in tandem, and the global economy is being squeezed. Meanwhile pollution from burning fossil fuels continues to pollute the planet. The world needs an abundant source of clean, transportable, inexpensive fuel. Could microscopic algae hold a key to that future? There has been a lot of hype surrounding oil production from algae lately. Visionaries claim algae holds the key to energy independence, but as exciting as oil produced from algae is, the reality is that a fossil-fuel-free economy is probably farther off than many...

    Remember the optimist's creed, "If life gives you lemons, make them into lemonade"? Well, ConocoPhillips and the Colorado Center for Biorefining and Biofuels are trying to do one better in a new, $5 million research partnership: "If life gives you pond scum, turn it into alternative fuels. And while you're at it, fight global warming." OK, trying to cram two good ideas into one slogan may make it too long for bumper stickers. But it is a classic example of the creative thinking that promises to reshape Colorado's future while creating jobs in the new energy economy. Making fuels from...

    SHELL is to become the first major oil company to produce diesel fuel from marine algae. Algae are a climate-friendly way to make fuel from carbon dioxide. They produce an oil that can readily be converted to diesel, and can be fed CO2 directly from smokestacks. Unlike biofuels such as corn, they don't use up soil or water that could otherwise be used to grow food, which can pump up food prices. The US government abandoned research on algal biofuel in the 1990s because of the low cost of crude oil. But as oil and food prices began to rise,...

    ST. PAUL, Minn. - The 16 big flasks of bubbling bright green liquids in Roger Ruan's lab at the University of Minnesota are part of a new boom in renewable energy research. Driven by renewed investment as oil prices push $100 a barrel, Ruan and scores of scientists around the world are racing to turn algae into a commercially viable energy source. Some varieties of algae are as much as 50 percent oil, and that oil can be converted into biodiesel or jet fuel. The biggest challenge is slashing the cost of production, which by one Defense Department estimate is...
