Trash-fed Generator Tested in Baghdad

The US military is looking to cut back on two things in Iraq: fuel consumption and levitra tablets for sale trash. So they’re finally getting on board with alternative fuel sources, using the trash they don’t want to get the fuel for electricity they need.

In March, we let you know that trash-to-fuel generators were getting shipped to levitra alternative Iraq. Well, they've arrived and are being tested.

If you’ve ever worked for the military, you know they don’t speak English, but Acronymish. So, the generator is called TGER (“tiger”) and the tramadol 300 mg acronym stands for Tactical Garbage to Energy Refinery. The prototype, which uses a variety of technologies to run an electrical generator, will be tested until August. If it works, more are on the way to smaller camps and possibly to disaster relief sites.

Right now, the military burns the trash in incinerators, emitting icky emissions and eating up a lot of fuel, time, and human power since it takes quite a few people to run one. Also, cutting down on natural viagra pills the use of diesel fuel is especially important since the trucks that haul the fuel are basically moving targets sure to make huge bangs. Decreasing casualties is a priority, and what better reason to get on to using waste as fuel?

The prototype accepts trash in a chute at one end, and the wet and dry wastes are separated. The dry trash is crushed, pelletized, and fed into a gasifier where the pellets are heated until they’re turned into synthetic gas, which then fuels the generator. The wet waste is converted with the buy cialis for daily use use to enzymes into hydrous ethanol, which is then blended with synthetic gas to boost the generator’s output to 55 kw. There are hopes to improve the technology so that literally all trash goes in one end, and electricity comes out the other – kinda the goal we all have for waste-free living. And the improvements are needed, since start-up time is a full 6 hours, and takes up about 1 gallon of diesel fuel an hour. But once started, it is reported that it runs at 90% efficiency. I’m a little incredulous about that, but we’ll see what folks say at the end of August.

With folks like BlueFire and others already working on this, it seems like highly efficient, easy to use trash-to-electricity technology is on the cusp of being large scale reality.

Kudzu a Potential Biofuel

Ever since I learned about this ridiculously quickly growing plant and its gazillion uses, I wondered why it wasn’t getting utilized as a renewable resource for a whole range of products. It seems that a lot of people also wondered about that, enough to order cialis online without prescription look into using it as biofuel.


Researchers at the University of Toronto and the US Department of Agriculture are taking a close look at kudzu, a native plant of Asia that can grow more than 6.5 feet a week and is nearly impossible to get rid of. The team examined the usefull link viagra overnight delivery amount of carbohydrate in the plant – the part that gets turned into ethanol – at different times of year in different parts of the plant. They found the root carries over 2/3 of the carbs by weight, and they estimate kudzu could produce 2.2 to 5.3 tons of best quality levitra carbs per acre. This translates to 270 gallons of ethanol per acre, comparable to the ethanol yield of corn - which isn't saying much considering corn is on the low end of the energy yield spectrum.


Algae Diesel Meets US Standards

Diesel produced from algae is potentially the greenest biofuel available. In terms of energy produced per acre of land, algae biodiesel outperforms plant crop biodieselby more than a factor of 10. Compared to soy biodiesel, algae is more than 100 times as efficient a method for fuel production.

But will it run in my vehicle?

Soladiesel is an algae-derived diesel produced by Solazyme, Inc. In recent testing, Soladiesel passed American Society for Testing and Materials (ASTM) D-975 specifications as well as the new ASTM ultra low sulfur diesel (ULSD) standards. That is the only here buy prescription cialis without standard used for "diesel fuel oils suitable for various types of diesel engines."


The fuel's chemical composition is identical to that of good choice buy cialis online without prescription standard petroleum based diesel, and Soladiesel is fully compatible with the existing transportation fuel infrastructure. Having fewer particulate emissions, Soladiesel also has a more desirable environmental footprint than standard petro-diesel.

But where can I get it for my vehicle?

That still seems to be a few years in the offing, although the Solazyme press release did include the statement from Jonathan Wolfson, chief executive officer of Solazyme: "Solazyme's leadership in the green fuels space will continue to cialis 10 mg online grow as we now execute on our strategy for commercial launch." They will have some competition with Sapphire, and Green Fuel Technologies and PetroSun might beat them to the punch. But hopefully this will simply breed ever more efficient, cleaner biofuels.

LGF to Put Sugar in Your Tank

Sugar ethanol is setting up camp in the south! Over the next ten years, expect to see three new sugar mills and four new ethanol plants open shop in Louisiana, generating an estimated 100 million gallons of sugar-based ethanol annually. Louisiana Green Fuels, an investment group owned by Inverandino and the Lake Charles Cane Cooperative, has purchased three sugar mills ruined by hurricanes Katrina and Rita, one of which was state owned and lowest price for viagra purchased for $60 million. Funding for the projects is coming from the Santacoloma family of Columbia, which controls Inverandino.


Additional financial help is coming from the state of Louisiana itself, including issuing $133 million in industrial development revenue bonds through the Louisiana Public Facilities Authority, $100 million of which is tax exempt. With the likelihood of these mills and ethanol plants creating thousands of jobs and significant revenue for the state, it is no wonder Louisiana is doing what it can to help the what is levitra professional project along. LGF has also said it plans to buy the bulk of its sugarcane and sweet sorghum locally, further helping the Louisiana economy. However, it will be importing high-test molasses, refined sugar and common molasses. It is thought that sugar, which produces an eightfold return on the fossil energy used in producing it will outstrip corn, which only yields a 1.3 ROI. With the politics of and misunderstanding around corn ethanol already making biofuels socially messy, it will be interesting to see how a solid run towards sugar ethanol might change the farming industry, as well as our ideas about crops-as-biofuel.


However cellulosic ethanol is also on the rise, and in the south to boot. Mascoma’s process can take trash to cialis china sugar to ethanol, and with its source being waste rather than a farmed product, I think cellulosic can be a more sustainable way to go if we’re heading towards ethanol. But for now, alternative fuel is alternative fuel and the more research and options we see coming down the pipe, the better for future improvements.

Coskata Taking Next Step with Next-Gen Ethanol

Coskata, as we know, has partnered up with GM to provide cellulosic ethanol fuel for the test program of GM’s flex-fuel vehicles via Coskata’s demo commercial plant. Bolstered by this pair up, and along with support from Khosla Ventures, Coskata is growing again, looking to rustle up $50 million to open two new ethanol plants. Ethanol plants are expensive to create, as several upstarts have discovered, and for them to have the backing to open up two more commercial facilities by 2011, in addition to their currently-running pilot lab and currently-under-construction demo commercial plant, is a pretty big deal.

Their plans are for one plant to use gas from sugar processing, and the other from wood biomass, and would allow them to significantly up their production levels. With other ethanol companies giving way to costs, there is a bit less competition for Coskata to very good site levitra england contend with, however they aren’t taking chances. In addition to the Series C round raising $50 million, Coskata is planning to work with large partners who will lend operating experience and/or feedstock supplies. Recognizing their start-up status, CEO Bill Roe says that they’re all about working with major partners and working seriously towards the success of cellulosic ethanol.
