Ugly Watermelons Could Make Good Biofuel

New research has come out that indicates watermelon could make a good biofuel additive.  Now, I know you're immediately cringing because watermelon is a food crop and cheap viagra uk that spells disaster, but the good news is that no one is proposing that we start taking over arrable land with watermelon patches.

It turns out that 20 percent of every annual watermelon crop is unused because, well, it's ugly.  Misshapen or bruised fruit doesn't sell, so farmers leave them in the field and take a loss.  Those extra watermelons could be processed for their juice, which could then be made into biofuel.

What makes these disfigured melons biofuel-worthy?  Watermelon juice contains seven to ten percent directly fermentable sugars or easy ethanol.  While the buy viagra online canadian phamacy juice would have to be almost triple concentrated to be the sole feedstock in a biofuel, it would make a great additive to other biofuel blends that need to cheapest cialis online be supplemented or diluted.  Farmers could process the juice on-site and use it as an alternative fuel or sell it to biofuel-makers and make revenue on what would usually be wasted fruit.

Of course, a feedstock's potential to make ethanol isn't everything.  We'll have to see how watermelon-blended biofuels perform compared to other feedstocks and gasoline to know if harvesting their juice is worthwhile.

Navy Testing Biofuels in Fighter Jets

The Navy has put out a call to biofuel producers for 40,000 gallons of their best JP-5 aviation biofuel for use in test flights of the F/A - 18 Super Hornet.

The Navy will decide by the end of the month who gets the contract for the test flights.  The choice of company will determine what feedstock will be used in the fuel, but jatropha, camelina and algae are all likely to be in the running and no food crops are being considered.  Regardless of viagra usa which type of feedstock is chosen, it will be used in a 50/50 blend with petroleum-based jet fuel for the tests.

Ground tests of the biofuel will be conducted at a General Electric facility in the coming months and within the next year test flights will begin, covering at least 15,000 miles. Boeing recently conducted a successful test flight of a 747 using a 50/50 blend of jatropha and jet fuel and saw significant fuel savings and emission reductions.  It will be interesting to see if biofuels perform as well in a fighter jet.

The Navy hopes to have completed testing and approved a biofuel for use in their fighter jets by 2013 and is viagra no prescription looking to do the same for its ships in the same time frame.

Zoo Animals Could Hold Key to Butanol Biofuels

Researchers at Tulane University are hoping that the droppings of zoo animals could hold the key to butanol biofuels.  We've written before about "zoo poo" being collected for environmental good, but in that scenario, the zoo was using the feces itself to power its facilities.  This time, the scientists won't be using the poo directly, but the bacteria within it.

The researchers are looking to extract the bacteria that breaks down cellulose in the animals' bodies.  They've collected several strains from a variety of plant-eating animals at the Audubon Zoo.  Ideally, this bacteria will be geneticallly modified to produce more and then used in landfills, ultimately turning that waste into fuel.

Butanol has a lot of us made viagra advantages over ethanol.  It can be easily blended with gasoline, distributed through existing pipelines and can be used in internal combustion engines without any modifications.  It also can be made from waste instead of from crops that compete with food sources for land.

The scientists hope to viagra cialis canadian pharmacy have enough butanol produced by the end of the year to power a small motor.

Exxon Embracing Algae Biofuels

Exxon Mobil has announced that they're jumping into the fda approves viagra biofuel business.  The oil giant is investing $600 million in researching algae-based biofuels that would capture CO2 and perform as well as oil-based fuels.

The company is teaming up with Synthetic Genomics Inc. to genetically engineer algae strains for testing.  If the partners are successful in developing a greenhouse gas-capturing fuel, Exxon will then invest billions on the production of the fuel.

The company envisions placing the algae farms near power plants and other major CO2 emitters to feed the algae and to help curb the impact of those businesses.  Exxon said they imagine a successful commercial production of an algae-based fuel could take up to a decade.

This venture isn't the company's first foray into carbon capture.  In January, they announced they were spending $170 million on carbon capture projects at their natural gas plants.  These projects are undoubtedly more financially driven than environmentally, but if the planet can benefit from their discoveries, it's worth paying attention.

PetroAlgae Promises Fuel and Food from a Single, Renewable Source

You wouldn’t guess that a bit of green slime could do so much. But from from food to fuel, PetroAlgae, Inc. seems to have thought of everything. This Florida-based renewable energy company has developed a technology in which algae and other microorganisms produce fuel to feed cars, animals, and even humans...and say they can do it cheaper than anyone else.

With the addition of a few basic nutrients, algae gather most of how can i buy viagra in canada their energy from the buying cialis sun. The result is a protein and carbohydrate-rich slime that can be converted to a variety of products. First, the protein is extracted and processed into animal feed or blended into human food products. PetroAlgae actually lists one of its products as “meal replacer”, conjuring images of our new utopian future in which chewing is obsolete.

After the protein extraction, what remains is a “lipid-carbohydrate mash”. PetroAlgae claims that this material can be sent directly to a petroleum refinery and processed into diesel, gas, or jet fuel without the need to retro-fit any of the refinery’s conventional equipment. Algae cultivation requires very little square-footage relative to conventional crops, can be grown on non-arable land, and consumes up to twice its weight in carbon dioxide as it grows.

In addition to algae, PetroAlgae draws from a large pool of microorganisms including diatoms, cyanobacteria, and micro-angiosperms (tiny flowering plants). While exact species remain unnamed, the company conscientiously notes that they use only species indigenous to the region in which a production facility will be installed. They have already begun licensing their technology to commercial facilities in Asia, and are poised to buy cialis on line complete contracts with the U.S. and several European countries this year. Each licensee is online cheap cialis promised the potential to produce 1.5 million barrels of transportation fuel per year, or the equivalent of 1.4 billion miles for a single truck. If PetroAlgae’s assertions hold true, the cost of fuel production is essentially paid for by the revenue from food and feed products, meaning that their microbe-derived fuels will remain competitive with fossil fuels, at any price.

PetroAlgae is in the business of licensing its technology rather than building the algae plants itself. It already has deals with algae farms in India and only now generic levitra soft tabs China and is currently working on online pharmacies deals in the U.S., Canada and Europe.
