​Cheap, Efficient Organic Flow Battery Materials
Written by Philip Proefrock on 13/01/14   

The science of power storage has a new variety of options and buying cialis without prescription new materials to investigate thanks to some recent developments in the chemistry of materials used in flow batteries. Until now, flow batteries have largely relied on metallic compounds for the active chemicals they use. But new materials have been found that are cheaper and more effective than the order cialis chemicals which have been most used in flow batteries until now.

The research undertaken by scientists at Harvard University has identified a range of organic compounds known as quinones, which are have the potential to cheap discount cialis be especially useful for flow batteries. Initial research indicates they are inexpensive and efficient materials well suited for use in power storage. A recently published paper in the journal Nature discusses the use of 9,10-anthraquinone-2,7-disulphonic acid (AQDS), a compound found in rhubarb, in a flow battery.

Large-scale energy storage is an area where flow batteries can excel, because the equipment needed to build a large energy storage system is basic, industrial gear, rather than highly specialized equipment. To increase storage capacity, a flow battery just needs a couple of viagra sample india larger storage tanks.

The AQDS materials are naturally abundant and very stable. They are potentially safer than metal-based flow batteries because the materials are "less likely to react violently if they accidentally come in contact with each other." When used in a flow battery, they show very good cycle efficiency and "[represent] a new and promising direction for realizing massive electrical energy storage at greatly reduced cost." The chemicals needed to store a kilowatt-hour of energy would cost $27, which is roughly one-third the cost of other systems.

Auto Show - Less Green in 2014
Written by Philip Proefrock on 15/01/14   

As we've done for the past several years, EcoGeek went to this year's North American International Auto Show (the Detroit Auto Show) to see what is new in clean and green transportation. However, this year's displays continue to move away from a focus on environmental awareness as a major selling point. This has seemed to be the trend over the past few years. In retrospect, it seems that the cialis online discount order cialis online not fake peak of the green focus was probably the 2009 Detroit Show.

Green isn't gone entirely. MPG is still a factor that is cialis online sales touted at some brands, but it seems to matter no more than other numbers like horsepower or cargo volume that manufacturers use to www.tedxamsterdamed.nl compete with one another. Electric drive continues to work its way into more and levitra australia more cars (with mild hybridization becoming more common). But cars are not green-focused the way they were a few years ago. The fact that Ford has five different hybrid and electric drive vehicles would have been a big story just a couple years ago, but now it is just part of a major automaker having a complete line.

Where once they seemed like an outsider, Tesla seems to have developed into a mainstream member of the club. For this year's display, Tesla had two of their Model S coupes and display panels about interior finish choices; the Roadster was not in sight. The only non-traditional manufacturer on the display floor this year was VIA trucks, which had vehicles in three different places. Michelin (who has always been a major sponsor of where to order cialis online the Detroit Show) and a couple other parts suppliers also had space on online viagra lowest price the main floor, but not to the extent as during the depths of the economic decline.

The common theme across much of the show this year was the levitra prices engine-on-a-stick. It's not that it hasn't been done before, but it seemed to be much more prevalent. Lots of "here's what the engine looks like," and usually nothing, or very little, in the way of explanatory text to accompany it. Overall, the show did seem to be moving back toward a more car-centric focus on the basic stuff that the core car-people really love. With that in mind, it's not at all surprising that the Chevrolet Corvette Stingray was named Car of the Year.

The driving course on the lower level is gone this year, as well. When it was introduced a few years ago, there were literally dozens of different vehicles, primarily electrics and hybrids, that could be driven, to introduce the public to the experience of where can i buy cialis driving a vehicle with something other than a gasoline engine. Over the past few years, this became less and less of a feature, and is now completely omitted from the show.

Although green cars have largely become a sideline, rather than the focus of the Auto Show, the fact that they have become a part of most manufacturers' lines should be taken as a sign of progress. There certainly were some interesting new vehicles at this year's show, and we will take a more detailed look at some of these.

Making Bio-Based Rocket Fuel
Written by Philip Proefrock on 27/03/14   

Rocket fuel is the latest in a long line of fuels being developed from bio sources instead of being produced from petrochemicals. Numerous other fuels have been developed from bio-diesel and synthetic gasolines to aviation fuels are now being made from microorganisms or from converting bio feedstocks. And now, scientists from the Georgia Institute of www.grantontrailers.com Technology and the Joint BioEnergy Institute have been able to http://www.rickgenest.com/viagra-prescription produce a key component of JP-10 high energy fuel from bacterial sources.

Pinene is a component that is used in fuels that are used for missiles and can i buy ultram online rockets. It is found in tree sap, but it is primarily extracted from crude oil. Since only a small amount of pinene can be produced from each barrel of crude oil, it is expensive and difficult to obtain.

The researchers developed strains of E. coli which has been able to produce small quantities of pinene in the laboratory. There are still further steps to take before this becomes scalable and commercially viable, but the cheap viagra in usa initial development has been the major milestone, and researchers on the project expect to be able to further improve the process as they continue their work.

There is also a much stronger economic drive to develop bio-based rocket fuel as compared to other fuels. At present, petroleum-based JP-10 costs about $25 per gallon, so a difference of a dollar or two per gallon could be significant, as well as being able to produce fuel for space travel without needing ot rely on petrochemical sources.

More Efficient Flight in Formation
Written by Philip Proefrock on 22/01/14   

Many people are very familiar with the V formation used by migrating flocks of birds, and scientists have determined that this is visit web site mexico levitra an efficient mode of travel which helps the birds conserve energy, especially on long migratory journeys. But the same concept is being considered to improve the efficiency of commercial jetliners.

Among aircraft manufacturers, Airbus is one of the companies looking at the advantages of commercial flocking. "In a V formation of 25 birds, each can achieve a reduction of levitra and diarrhea induced drag by up to visit web site buy now online viagra 65 per cent and increase their range by 7 per cent. While efficiencies for commercial aircraft are not as great, they remain significant."

It is possible that, in the future, commercial flights might flock together in this way to save fuel. The initial tests of this approach might be carried out with trans-ocreanic flights originating in separate Australian cities which would coordinate their schedules and meet up in order to cross the Pacific together, before they "peel off and head to their separate destinations."

Nontoxic Flame Retardants from Whey
Written by Philip Proefrock on 02/04/14   

Whey is generally a waste byproduct from cheese- and yogurt-making. Producers need to find ways to dispose of it, and often it is discharged into wastewater systems. Research at the Polytechnic University of Turin is being done to cheapest prices for viagra explore the use of whey as a replacement for toxic compounds used as flame retardants.

Treated fabrics are kept from burning as readily because the casein from whey forms a layer of char on the surface when it is exposed to heat, which prevents the fire from spreading as readily. Tests on cotton and polyester materials often self-extinguished, and tests on look here levitra professional no prescription cotton-polyester were also inhibited and www.americanfoods.com burned more slowly.

While the tests have been promising, the process is not yet ready for commercialization because "the cheese-treated fabrics stink." But, if the compounds that cause the odor can be removed, this can be a technology to remove more harmful chemicals from common use and make use of a waste product at the same time. And, it could give the tramadol pain killer without a prescription word "cheesecloth" a whole new meaning.
