Cow Biogas Provides Clean Energy, GHG Reduction



As a greenhouse gas, methane is 21 times more powerful than carbon dioxide when it comes to cialis without prescription canada retaining atmospheric heat. And so, although it generally gets less face time in the canadianpharmacy press, it accounts for a disproportionately large chunk of global GHG emissions. Where does the methane come from? Cows, mostly. At the tail end (pardon the pun) of their digestive system, they release methane; either directly or through the decomposition of their waste.

Capturing this methane, then, reduces GHG emissions. Additionally, cow-produced methane is a renewable energy source that, after a little cleaning, can be added into the natural gas pipeline. That is exactly what BioEnergy Solutions is doing in Kern County, CA. They have recruited three large local dairies to harness the 650,000 cubic feet of gas emitted by their 6,500 dairy cows. That’s enough to power a couple hundred thousand California homes!

On each farm, all the cow manure is collected and i use it levitra soft tabs mixed with water in a covered lagoon-like area. This causes the www.auburg.de manure to decompose and release methane. BioEnergy built the pipelines to connect the three farms, collect all the methane, treat it so that it meets natural gas standards, and finally feed it into a PG&E pipeline.

Obviously, the benefits of cow-produced biogas do not extend very far beyond those regions rife with dairy farms. But in Kern, there are still six other major dairy farms that could be tapped, which would triple the benefits currently in place. Let’s hope they wake up and smell the… coffee.

Air New Zealand and Boeing to Conduct Biofuel Test Flight

In late October, Boeing announced that they would be phasing in biofuel blends within the next three to five years. At the time, there wasn't much information about what type of biofuel they'd be using or when they'd be conducting a large scale test. In a press release yesterday from UOP, it was revealed that the company would be participating in a test flight scheduled for December 3 in partnership with Air New Zealand, Boeing and Rolls Royce.

The 747-400 jet will take off from Auckland and will run on rx generic cialis a 50/50 blend of wow look it soft levitra tablets Jet A-1 fuel and a synthetic paraffinic kerosene derived from jatropha that was developed by UOP. Rolls Royce conducted engine tests with the blended fuel and found that it met all specifications for jet fuel.

Jatropha is a plant that produces seeds that contain an inedible oil that can be extracted to robert-alonso-photos.com make fuel. The plant oil for this test flight was sourced from non-arable lands in India, Malawi, Mozambique and www.breinweb.nl Tanzania.

More flight details are supposed to be released closer to December 3, but it's interesting that Boeing previously indicated that they'd be using 30 percent biofuel blends, but this test will be performed with a 50 percent blend. It's encouraging that they were able to find a larger percentage blend that performed just as well.

Amyris Pilot Plant Online

It seems like every day another microbe-based biofuel startup announces its presence, and gets its 15 minutes of fame. However, only a few of these startups are anywhere near ready to bring their technology to scale. It is important to focus on these companies, because that step – bringing the usefull link price levitra technology to scale – is the biggest challenge, the highest hurdle to cheapest cialis uk clear.

This week, by opening up a pilot plant in California, Amyris hopes to show that they can do just that.  They aren’t the only ones this far along the path to commercialization – Petrosun, Solazyme, Greenfuel and Sapphire are hard at work trying to grow algae in a variety of ways.

What’s Amyris’ angle?  First of all, they aren't growing algae, but rather yeast.  They are experts when it comes to customized genetic engineering. They started out as a pharmaceutical company, mass producing an anti-malaria drug. They did so by tweaking the metabolic pathways in their yeast - essentially using the organisms as factories, and rearranging the machines to build the exact chemical they wanted. Now they are applying that technique to biofuel. Rather than simply picking organisms with high fat content (which is what most of the discount viagra sales algae startups are doing), Amyris is viagra soft tablets designing a yeast strain that will make a proprietary molecule that they have chosen specifically because it will make a good fuel.

Now that the pilot plant is operational, Amyris expects another year and half before they start full scale commercial production. Until then, it looks like one of the issues they will be focusing on is sourcing the sugars they need to feed the yeast. They have recently partnered with a Brazilian company, Crystalsev, which currently operates ethanol plants. Crystalsev already has plenty of look here where can i purchase viagra feedstock (which they use to cheap propecia order online make ethanol), and they also have the infrastructure necessary to export and distribute the fuel.

Glycerin: A Natural Replacement for Antifreeze?

Toxic chemicals ethylene glycol and propylene glycol have been the preferred engine coolants for decades. Glycerol (glycerin) was once used as a coolant, but it was expensive and it's a weaker freezing point depression ruled it out.

This may all change soon. Glycerin is a natural byproduct of biodiesel, so while biodiesel is starting to be produced in large quantities, so is glycerin. This new abundance of glycerin has made it cost competitive with its more toxic counterparts.

SAE International did an extensive evaluation of glycerin's performance in heat transfer, corrosion protection, freeze point, thermal stability and toxicity. They concluded that glycerin should be reconsidered as a less toxic base for antifreeze.

I like the idea of reducing waste by coming up with uses for a byproduct. Eliminating or reducing waste in manufacturing will need to be a star player in our move towards a cleaner planet or we'll never get there. Plus a reduction in a product's toxicity is always a step in the right direction.

Fungus Fuel



Fill your gas tank with fungus fuel? It sounds far-fetched, but it could be a promising alternative to fossil fuel. A Montana State University professor has found a fungus from the propecia 1 mg on sale Patagonia rainforest that produces a new type of diesel fuel. Other simple organisms such as algae have been known to make chemicals similar to hydrocarbons in transport fuel, but this fungus could do even better than that.

Emeritus plant pathologist Gary Strobel, who 15 years ago discovered the fungus that contained the anticancer drug Taxol, found that this new discovery, called Gliocladium roseum, is capable of producing gases. Further testing of the fungus revealed a number of cialis online 50mg compounds normally associated with diesel fuel, which is obtained from crude oil. The initial observations of the fungus' output, which Prof. Strobel calls “myco-diesel” were published in this month's issue of Microbiology. The abstract can be read here.

The gas composition of G. roseum included hydrocarbons and buy viagra professional 24h hydrocarbon derivatives. A spoonful of the stuff could run a diesel engine with further refining or modifications to it. “The results were totally unexpected and very exciting,” says Prof. Strobel. “Almost every hair on my arms stood on end.”

Prof. Strobel travels the world looking for plants that may contain beneficial microbes and first collected a variety of specimens, including the G. roseum, from the Patagonia rainforest in 2002. He kept the G. roseum in storage until last year when he finally had time to wow look it cialis online canada work on it. While he hopes that myco-diesel could be an option for those seeking alternatives to other biofuels like ethanol, the big question remains of whether the microbe can be scaled up to commercial levels.

The findings have led Strobel to even speculate that organisms such as G. roseum may be responsible for the the best site herbal alternative to cialis world’s crude oil deposits. This is look there viagra pharmacy in india quite a departure from the traditional theory – that oil is only produced when decaying organic matter is subjected to pressure and millions of years. An intriguing possibility, but for the time being scientists have their hands full trying to figure out how to turn these volatile, oily vapors into biofuel.
