Biodiesel is the green alternative to gas, but seems it takes more green to buy it these days. According to Treehugger, buying biodiesel in the Seattle area is about $1.20 per gallon more than mineral diesel, and it has nearly doubled in price over the last year. The cost of production is a major factor, since just buying enough soybeans for a gallon of biodiesel costs nearly as much as a gallon of pump-ready mineral diesel. Add on the only for you cialis online pharmacy cost of production, and it’s already more expensive, and therefore less desirable to the average consumer, than diesel, proven by the 66% drop in biodiesel sales in Washington state over the past year. Imperium Renewables hopes to ride this out by exporting more of their fuel and focusing on non-food sources, including jatrpha, an oily seed that grows in barren areas (I wonder what fuel they’d use to transport jatrpha from harvest to viagra overnight delivery refinery?).
Some folks say that biodiesel is chalk full of problems, including affecting food prices and taking over farm land. Unless we are able to utilize waste materials as raw material for ethanol or figure out a solid and cialis how much affordable method for solar powered vehicles, which beats out all biodiesel crops with algae coming in second, there is little we can do to keep farmers from switching to growing crops for biodiesel, regardless of what that crop is composed of, if that is more profitable for them. As proof of cheap tramadol fedex overnight all the questions and concerns about biofuels, Iowa State University reports that last year the US only produced 500 million gallons of biofuel of its 1.85 billion gallon capacity, with over half of that biofuel going to Europe. Nonetheless, Imperium Renewables is taking a crack at making biodiesel consumer-friendly again, getting a little help as Washington state (home country for Imporium Renewables) will require 2% of diesel sales to be biodiesel starting in December, equating to about 20,000,000 gallons if Washington meets or exceeds the 1 billion gallons of diesel consumed in the state last year. We’ll keep an eye on their progress, as well as that of the industry as a whole.

Traditional methods of producing ethanol generally revolve around the digestion of waste plant matter from farms, switchgrass, corn, or even rice husks. BlueFire Ethanol of Irvine, California, however, has plans to webstuff.nl build a facility later this year that will be able to produce 3 millions gallons of ethanol each year, from trash. That's right, your unwanted waste might one day find its way into your fuel tank.
Their current process, using sorted garbage can produce 70 gallons of fuel per ton of waste. They hope to improve this to reach 100 gallons per ton. Any way you look at it, it's good news. Trash is cheap, and by locating their plants next to landfills, which they are doing, their source of raw materials is right next door, meaning that expensive feedstock doesn't need to be trucked in. This allows the ethanol to be cheaper than traditional processes.
Instead of using microorganisms to break down plant matter, BlueFire is using a concentrated acid hydrolysis process, where sulfuric acid is sprayed onto the trash, which is then submerged in a bath and pressed. The resulting mash is then fermented into ethanol and the acid reclaimed to wow look it online cialis prescriptions use again. In addition to the plant they are currently building, two more are in the works producing 17 and 55 millions gallons respectively.
"When you are talking about waste streams, there are maybe 15 or 20 landfills in the U.S. that could sustain a 100- to 150-million-gallon-per-year ethanol plant," says CEO Arnie Klann. "We're looking at those locations to build out, but the vast majority of landfills will handle that 17 million-gallon-per-year size."
We already know cellulosic ethanol works, so if they can produce it from trash at the right price and enough output, BlueFire can position themselves to be big competitors in the market against producers like Range Fuel, who is building the US’s first cellulosic ethanol plant with a goal to produce 100 million gallons of fuel a year from tree waste, or even nudging up with Coskata (who is already producing ethanol from municipal waste) and Mascoma, both of whom have deals with GM. The realm of cellulosic ethanol from trash is an exciting development to keep track of.
The title might sound impossible, but Sapphire Energy, a California-based company, has been working away to create actual gasoline from a renewable, carbon neutral source: algae. While we've heard of many different processes for making fuels from algae, this one certainly tops the list. They've managed to drug generic viagra produce 91-octane, ASTM certified gasoline, ready to be pumped into your car. They stress that it is not ethanol, and not biodiesel.
The company, they say, started with 3 friends discussing a very interesting question: "Why is the biofuel industry spending so much time and energy to manufacture ethanol â€” a fundamentally inferior fuel?" A very good question indeed, and one they sought to answer on their own terms. The friends - a bioengineer, a chemist, and a biologist - set out to recruit the best minds they could find to collaborate with them on the project, and the results are staggering. "The company has built a revolutionary platform using sunlight, CO2 and microorganisms such as algae" to produce the fuel, without the use of woman and cialis arable land, and while we haven't yet seen any data, they claim it to be very water efficient.
They also announced that they raised $50 million from Arch Rock Ventures, Venrock, and the Wellcome Trust. It is evident that Sapphire will become a major player in the coming years for alternative fuel production, and one cannot help but be inspired with confidence when Arch Rock says: "We realized at that point we could change the world, so we sat them down and told them, 'the checkbook is completely open; tell us what you need'." Not a statement you hear everyday from a venture capital firm.
We will have more on this story as it develops; we are eager for more info and levitra prices uk will pass it on as soon as we get it.
I'm the first to www.transitofvenus.org admit that the current round of ethanol is not perfect. The rising demand for ethanol has put more land under cultivation, increased water shortages, and increased fertilizer and pesticide use. For all that, corn isn't really a great way to create ethanol, only producing 1.3 units of energy for every 1 unit put into its creation.
However, it is NOT responsible for the 40% increase in food prices over the last few years. It might seem like an easy target, but let's start with some logic, and then move into the solid figures.
First, how could an increased demand for non-edible corn (used mostly to make high fructose corn syrup and feed for cattle, chicken and pigs) increase prices of pasta in Italy, onions in India and rice in China?
Second, is there any other trend, besides the increase in biofuel production that could be blamed for rising food costs. Any trend at all? Possibly a larger, more global, more significant, and much more difficult to deal with trend?
Yes, it turns out that there are two such trends. The rising prosperity of people in the world, who are now happy to be eating more (and more meat). And second, the related rise in fuel prices, due to increased demand in developing countries.
Of the 40% increase in food prices, about 3% can be attributed to food crops being used in biofuels. At least 8% (PDF) can be attributed to rising costs of fuel used to grow and transport the crops from farms to www.slic.de the grocer. But the big hunk comes in with increased demand.
As the world has become more prosperous, more people have begun to eat more food. Particularly in China and India, more people have begun to eat meat regularly. Simultaneously investors, seeking non-mortgage or debt-based assets to invest in, have begun to speculate on food crops. Assuming that costs will continue to increase along with increased affluence in the developing world, the commodities markets in food products have spiked.
Simultaneously, fertilizer prices have skyrocketed as they are also created from petroleum, and peculiar weather patterns and cheapest price on cialis frequent droughts, possibly linked to global warming, have limited supply.
All-in-all, it's not a good time to be burning what can otherwise be eaten. But there is no good reason to say that biofuels are the orignal viagra online uk one and only problem. SUV's are certainly limiting the future of the world, but not by burning hungry people's food.
Corn ethanol is never going to be the whole solution, and we are very excited about the many cellulosic ethanol companies entering the market, but I'm tired of medication tramadol 50 mg hearing about the supposed evils of ethanol. Let's lay the blame where it belongs...greedy commodity investors, meat production, and the rising price of oil.
