A Texas startup says that it has taken a huge step toward high-volume production of an ultracapacitor-based energy-storage system that, if claims hold right, would far outperform the best lithium-ion batteries on the market.

Dick Weir, founder and chief executive of EEStor, a startup based in Cedar Park, TX, says that the company has manufactured materials that have met all certification milestones for crystallization, chemical purity, and particle-size consistency. The results suggest that the materials can be made at a high-enough grade to meet the company’s performance goals. The company also said a key component of the material can withstand the extreme voltages needed for high energy storage.

“These advancements provide the pathway to meeting our present requirements,” Weir says. “This data says we hit the home run.”

EEStor claims that its system, called an electrical energy storage unit (EESU), will have more than three times the energy density of the top lithium-ion batteries such as IBM ThinkPad R60 Battery, IBM ThinkPad T60 Battery, IBM ThinkPad X60 Battery. The company also says that the solid-state device will be safer and longer lasting, and will have the ability to recharge in less than five minutes. Toronto-based ZENN Motor, an EEStor investor and customer, says that it’s developing an EESU-powered car with a top speed of 80 miles per hour and a 250-mile range. It hopes to launch the vehicle, which the company says will be inexpensive, in the fall of 2009.

But skepticism in the research community is high. At the EESU’s core is a ceramic material consisting of a barium titanate powder that is coated with aluminum oxide and a type of glass material. At a materials-research conference earlier this year in San Francisco, it was questioned whether such an energy-storage device was possible. “The response was not very positive,” said one engineering professor who attended the conference.

Many have questioned EEStor’s claims, pointing out that the high voltages needed to approach the targeted energy storage would cause the material to break down and the storage device to small out. There would be small tolerance for impurities or imprecision–something hard to achieve in a high-volume manufacturing setting, skeptics say.

But Weir is dismissive of such reactions. “EEStor is not hyping,” he says. Representatives of the company said in a press release that certification data proves that voltage breakdown of the aluminum oxide occurs at 1,100 volts per micron–nearly three times higher than EEStor’s target of 350 volts. “This provides the potential for brilliant protection from voltage breakdown,” the company said.

Jeff Dahn, a professor of advanced materials in the chemistry and physics departments at Dalhousie University, in Nova Scotia, Canada, says the data suggests that EEStor has developed an “amazingly robust” material. “If you’re going to have a one-micron dielectric, it’s got to be pretty pure,” he says.

Ian Clifford, CEO of ZENN Motor, says that the news “bodes well” for EEStor’s next milestone: third-party verification that the powders achieve the desired high level of permittivity, which will help determine whether the materials can meet the company’s energy-storage goals.

Weir says that EEStor’s latest production milestones lay the foundation for what follows. It has taken longer than originally expected, he says, but the company is now in a position to deploy more-advanced technologies for the production of military-grade applications, alluding to EEStor’s partnership with Lockheed Martin.

Weir says that momentum is building and that he’ll start coming out with information about the company’s progress on a “more rapid basis.” Plans are also under way for a major expansion of EEStor’s production lines. “There’s nothing complex in this,” he says, pointing to his past engineering days at IBM. “It’s nowhere near the complexity of disk-drive fabrication.”

Despite its critics, EEStor has won support from some significant corners. In addition to Lockheed Martin, venture-capital firm Kleiner Perkins Caufield & Byers is an investor, and former Dell Computer chairman Morton Topfer sits on EEStor’s board.

The company is also in serious talks with potential partners in the solar and wind industry, where EEStor’s technology can, according to Weir, help place 45 percent more energy into the grid. He says that the company is working toward commercial production “as soon as possible in 2009,” although when questioned, he gave no specific date. “I’m not going to make claims on when we’re going to get product out there. That’s between me and the customer. I don’t want to tell the industry.”

Dahn says that he hopes EEStor will succeed. “I hope it works like a charm, because it will be a lot simpler than fuel cells and batteries if it comes to pass.”

How to Better Apple MacBook 13″ A1181 Battery Life

Posted on 29 August 2010. Tags: A1181, apple, Battery, Better, Life, macbook

Tip 1: Power Down the Show

Do you know one of the most effective ways to conserve laptop battery life is to lower the brightness of the screen show? Its been known that lowering one level of screen brightness will yield up to 10 more minutes of battery life. You can easily do this by going to Start > Settings > Control Panel > Show and clicking the Settings tab. You can also disable those cool effects like ClearType fonts and fade effects to reduce the CPU’s power consumption.

Tip 2: Decrease Hard Drive Activity

You can also optimize the Windows’ paging file – the area of the laptop hard drive that serves as virtual memory whenever your RAM is full. Optimizing the paging file size ensures your hard drive is accessed less frequently when you run out of system memory. To change it, go to the Control Panel > System > Advanced > Performance Settings > Advanced > Virtual Memory Change. Set both the initial and maximum paging file size to 1.5 times the capacity of your installed RAM size.

Your laptop hard drive is another power eating culprit. To save power, you should reduce the frequency with which your hard disk has to spin. To do this, you can try defragmenting your hard drive regularly. This can be done using the Disk Degfragmenter in the Start > Programs > Accessories > System Tools menu.

Tip 3: Condition the Battery

One thing you should remember about laptop batteries. You need to condition it. When you first buy your laptop, charge the battery to 100 percent and then discharge it completely. Next, charge it to 100 percent again. This is not a pointless exercise – it ‘conditions’ the battery and helps it remember exactly how much electrical charge it can hold. After you do that, you will never need to completely discharge the battery again.

Tip 4: Disable Startup Items

Here’s another tip. Disable your unneeded startup items! I find it very irritating whenever my laptop boots up and I’ve to wait like 20 seconds for all manner of small program bits to load into memory. You can disable those startup programs. Go to the associated programs and click on the Options or Preferences menu to do this. You can also go to the Startup tab in your Start Menu and clear programs you don’t want to run at boot time.

Tip 5: Turn Off Unused Devices

And here’s another tip for you. As you may know, many modern laptops have a Wi-Fi built in. Unknown to many people, that Wi-Fi connection is a power guzzler! Make sure you turn off the Wi-Fi connection using the external Wi-Fi on-off switch. If your laptop does not offer such a switch, you should go to the Control Panel > System > Hardware > Device Manager and disable the infrared transceiver, Ethernet adapter and Bluetooth radio.
Conclusion

I hope this article has shown you some excellent tips on conserving laptop battery life. Follow the above tips so that the next time you’re sipping coffee in Starbucks, you have lots of battery life left in your laptop for surfing and working. Until next time, pleased computing!

Posted on 18 December 2009. Tags: Alienware, Better, M15x, Sony, Think, VAIO, Vgnsr56ggb

Hey guys, I’m currently trying to figure out which is the better laptop: The alienware (customized a bit more) or the new standard Sony Vaio VGNSR56GGB.
Please help, because the alienware costs $500 (AU) more than the sony vaio.
I’m gonna be using this laptop for 3D animation (game design etc) so I want something excellent (but not over $3000).
Thanks for all your answers!

What Is Better For The Battery Life Of A Sony Vaio Laptop?

Posted on 08 December 2009. Tags: Battery, Better, Laptop, Life, Sony, VAIO

I bought a new Sony Vaio laptop yesterday and fully charged it. Now my question is: Is it better to take the laptop off the charger and use it ’till the battery is fully empty and then charge it again. Or is it better to just keep it plugged in the charger when I work on it (at home)?
