We knew that super-secretive, somewhat-sketchy start-up EEStor was working with Lockheed Martin on viagra and women SOMETHING. And, yes, that was exciting, since Lockheed doesn't generally work with companies who's technology doesn't work. But now we actually know what they're working on (thanks to the sleuthing of the folks at bariumtitanate.blogspot.com.) And all of this comes just days after EEStor secured the first patent for its technology.
EEStor, which promises a new kind of energy storage device ten times lighter than lithium-ion batteries looks to canadian generic viagra on line be talking to Lockheed about developing a power source for a wearable computer / body armor for U.S. soldiers. The EEStor unit will actually be a thin layer that surrounds the entire garment, with a thickness between 0.5 and 2 centimeters. Frankly, I really hope these go on sale at the GAP in the next couple years.
While the patent refers to a lithium polymer battery and http://www.roli-guggers.de/how-to-get-levitra-no-prescription a fuel cell, it also specifically mentions EEStor and refers to the power storage unit using EEStor's nomenclature the "electrical energy storage unit."
It isn't really 100% environmental technology in this current application, of course. But if it works in a soldier's body armor, then it'll work in electric vehicles too. Let's hope, for the G.I. Joes and the EcoGeeks, that it does work.
Personally, I'm very excited that lithium ion batteries are finally getting advanced enough to find homes in automobiles. But a small company called EEStor is canada generic viagra promising "Electronic Storage Units" that will be ten times lighter, hold ten times more power, and cost half as much as lithium ion batteries.
What's more, they'll be able hold enough power to drive a car for 300 miles, charge in less than five minutes (at charging stations, not at home outlets) and will be able to charge and recharge an infinite number of where to find levitra times.
If true, this isn't just great news for the auto industry...it's great news for consumer electronics and the power industry as well. The question is...is it true?
Well, one obstacle was overcome today, when EEStor was finally awarded a patent (PDF) on its technology. But a patent can be awarded for technology that doesn't work or isn't viable...they do it all the time. But now, at least, EEStor will be able to control the device if it turns out to be feasible.
It also opens up the window for all of us to look in on their mysterious chemistry a bit. According to the patent the viagra india device is a sort of capacitor that actually contains 31,353 separate capacitors in parallel. These nano-capacitors are basically a ceramic powder suspended in a plastic solution, and we're not going to www.ncitech.co.uk pretend we understand why they can soak up so many electrons.
In my mind, ultracapacitors and hydrogen play similar roles. They are both advanced, proposed forms of energy storage that always seem just over the horizonâ€¦ no matter how far along we travel. With hydrogen, the problem is not the power generating technology itself â€“ fuel cells exist, and they work great. The problem is that we have poor means of storing and distributing the fuel. Ultracapacitors have the opposite problem. The infrastructure for transmitting and recommended site order viagra pill generating electricity is all in place; what we lack are the actual ultracapacitors themselves.
Granted, scientists are hard at work trying to build these ultracapacitors, and with the nanotechnology available to material scientists today, there is good reason to believe it is within our reach. But Iâ€™m not such a patient guy, and I still want to see real live examples of ultracapacitors in action.
Looks like Iâ€™ll have to go to South Korea, because thatâ€™s where ultracapacitors from Maxwell Technologies (of San Diego) were shipped earlier this year, and are now being tested. The South Korean government has hooked them up to order tramadol without prescription a Korean subway system, where they will capture electricity from regenerative braking. A full demonstration of the technology isnâ€™t scheduled to happen until mid 2009, but for now Maxwell claims that tests are going well. They say that they could reduce grid consumption by 20%!
More importantly, if we see real, working, prototypes from Maxwell, that means that car-sized ultracapacitors might not be that far off. An ultracapacitor-powered electric vehicle is better than a lithium-ion powered one, because it can charge in minutes, rather than hours.
Maxwell! Bring some of those ultracapacitors to New York! Weâ€™ve got plenty of www.worcestercountybar.org subways here, let me tell you. In fact, I think I wouldnâ€™t mind the www.markwellgroup.com.au ear-splitting screetch of the 1 Train if I knew that all that braking was going to a good purpose. Well, not as much anyway.

Lithium-ion batteries may be impressive, but some people feel they can do better – with zinc. Power Air, a startup from Livermore, CA, is designing zinc oxide fuel cells. In their fuel cells, zinc is buy generic cialis online dissolved in an electrolyte solution, and exposure to the air causes zinc oxide to form, releasing electrons and generating electricity. In theory, the zinc oxide can be collected, reduced back to zinc metal and fed back into the cycle.
Zinc air batteries are already used in hearing aids, though companies like Power Air hope to build batteries more suited for power and charging mobile electronic devices. Toyota is even researching ways to generic levitra brand use zinc-air cells in electric vehicles, though they have put a 2020 timeline on the project, which means we won’t be seeing it any time soon.
As far as the chemistry goes, using zinc is no different than any other fuel cell, or regular battery for that matter (zinc, in fact, is a major component of most alkaline batteries). So what’s so special about it? It has two big advantages over something like lithium. Firstly, it is abundant and cheap, whereas there are fears about the supply of lithium. Secondly, it is safe and recyclable. It also has a relatively high energy density (energy contained per unit of volume).
Of course, it has its drawbacks. How would the zinc actually get recycled? Would battery owners have to recycle it themselves? How much energy would be going into reducing the zinc metal? And how does it make sense to make a car battery out of zinc? Zinc is far heavier than lithium, and delivers far fewer watts per pound… not ideal for a car.
Guess we’ll leave it to Power Air to show us that a zinc economy is feasible.
